June 15-19

Math:  Mock PAT Week is here!  During the coming week, there will not be new material.  Tuesday will be devoted to a practice Part A Math Provincial Achievement Test that students can access on D2L Quizzes.  This is the no calculator portion of the PAT.  This test is not the actual PAT.  Many students have asked to see what one would look like since they did not have the opportunity to write theirs.  Wednesday will be the Part B portion of the Math PAT.  This is a calculator multiple choice portion.  On D2L this past week, students can access packages of material that they did not cover due to COVID, if they wish.  As well, there is a no calculator test given by Joane Cardinal Schubert High School that informs grade 9 the concepts that they would need to know to increase their chance of success in Math 10C.  Good luck this week!

June 8-12

Math:  During the coming week, grade 9s will continue to investigate inequalities.  We will be graphing inequalities on a number line using the whole number and rational number systems.  Grade 9s will then move into solving inequalities in much the same form that they solved equations.  In a couple of weeks, grade 9s will be exposed to a practice Provincial Achievement test as many of the students have requested that they still have the opportunity to write a Math PAT via D2L.  

June 1-5

Math:  We will be wrapping up equation solving during the next week with a D2L quiz.  Students will then move into inequalities.  Inequalities are the less than and greater than that students learned at a very young age.  But, now, those two signs will now be used to solve inequalities, not equations, inequalities.  The process will be similar.  We anticipate that this concept will take us until mid-June.

Science:  

May 25-29

Math:  We will begin to wrap up equation solving over the next couple of weeks.  Grade 9s will receive a final review of equations next week.  Upon completion, they will be provided with the solutions to check their work before having a quiz the following week.

Science:  We will be talking about acids and bases. We will identify something as acidic, basic, or neutral based on its pH and look at the effects that acids and bases have on each other, on other substances and on living things.

May 19-22

Math:  During this upcoming week, grade 9s will continue to work with equation solving.  Because this skill is so necessary for high school, we will be spending a fair amount of time on it.  The only real difference between the equations in grade 9 compared to those in grade 8 is the complexity.  This year, we will be using a lot of negatives, decimals and fractions.  We will begin the week solving where students will receive the answer key so that they can check their own solutions.  Then, grade 9s will move into equation solving on their own.  Once their work has been submitted, they will receive an answer key to check their own work.  In the coming weeks, students will be submitting their work for feedback.  As always, if students are finding that they are not able to solve equations correctly, they are encouraged to tune into Google Meet sessions to troubleshoot their work.

Science:  We will be analyzing the data we collected from Riverwatch and determining how different factors of a river are connected. This data is one example of biological monitoring and can be used to make an informed decision on whether a body of water is healthy.


May 11-14

Math:  Whew…we have finished linear relations.  Looking at the quiz results coming in on D2L, you have done amazing, especially considering the fact that you are having to learn under a completely new platform.  We are going to spend some time moving into equation solving.  This is another concept that is so important for success in high school.  The procedures are the same as what students have experienced in grade 8, but now we have the wonderful privilege of using decimals, negatives and fractions in our equations.  Happy Solving during the coming week!

Science:  This week in Science we are looking at how chemicals enter organisms and what impacts some of these chemicals can have. We will then look at how toxins accumulate in food chains when they can’t be broken down by organisms.

May 4-8

Math:  This coming week, we will look at wrapping up linear relations.  We will spend a few days reviewing before completing a D2L quiz on linear relations at the end of the week.  We would then like to spend some time solving equations.  This is just a continuation of from grade eight.  Both linear relations and equation solving are quite important for success in high school.

Science:  This week we will be looking in more depth at organic and inorganic compounds and more specifically how our bodies use them.

April 27-May 1

Math:  During this past week, many of you have worked so hard with linear relations.  We will continue with much of the same during this coming week.  We will have continued exposure to these concepts so that nothing will come as a surprise.  This work will need to be submitted and will be checked carefully with feedback provided.

Science:  This week in Science we will be finishing off our Matter and Chemical Change unit talking about endothermic and exothermic reactions as well as factors that impact the rate of a reaction. We will also be starting our Environmental Chemistry unit with a look at organic and inorganic compounds.

April 20-24

Math:  So many grade 9s continue to have such amazing weeks with this temporary change in learning!!!  We are so impressed with you!

This past week, we have begun some work with linear relations.  Much of this is based on what students had done in grades 7 and 8.  We have revisited tables of values, equations and graphing.  We have decided that it would be beneficial for our grade 9s to cover these concepts to be better prepared for next year.  For the upcoming week, we will continue our work with linear relations.  We will explore the equations of horizontal and vertical lines as well as equations being written in a different from that we have been using.

Science:   Grade 9’s will be learning the types of chemical reactions. We will be building on our last two weeks of recognizing chemical formulas and using those to recognize which chemical reaction is occurring based on the reactants and products.

April 14-17

Science:   Monday is a PD day, so no lessons that day.  This week will be learning how to name Covalent Compounds and explore how this compares to Ionic Compounds.

Math:  During this week, grade 9s will finish their circle geometry with an online D2L quiz.  There are 14 questions that students will have the entire week to complete.  Please have it submitted by the end of the day on Friday (at which point, the quiz will close).  In addition, we will be moving forward with the beginning of linear relations.  Again, this will include two lessons that will involve reading through notes and examples and making your best effort on linear relation practice.

April 6-9

If parents want to see all of your child's courses, please use this link to learn how to log into D2L  (parents must log in as student to view full courses and content) https://www.youtube.com/watch?v=lNSVuKsFpbo&feature=youtu.be

Math:  We were working on Circle Geometry prior to our shut down and would like to pick up on the same.  We will spend the week (which is only 4 days) doing some review of circle geometry.  Ms. Chaudhary (with 9-1 and 9-2) and Mr. Honish (with 9-3 and 9-4) will be available online from 2-3 all four days for those that require assistance.  This is quite a learning experience for students and staff, so we appreciate all of the support you have offered so far, especially to your students.  Thanks so much!  Stay safe.

Science:  Ms. Mak will have posted information on the Science D2L shell for all grade 9 students.

March 31-April 3

Students have been sent an email instructing them to log into D2L.  A small assignment has been posted for students to complete this week.

March 23-30 SPRING BREAK

Teachers will be in contact with students and parents after Spring Break.

March 16-19

Math:  All classes are planning on wrapping up their Circle Geometry during the coming week.  Students should plan for their unit final during the week and having everything done before the spring break.

Science:  The students are working through the chemistry unit and have finished writing a quiz on trends in the periodic table. The quizzes have been marked and reviewed and students are able to do a “corrections quiz” if they would like to improve their understanding. Next week, we will be learning how to write a formal lab write up as well as doing a lab that involves exploring chemical and physical properties and changes. 

March 9-13

Science:  The students have learned how to find the protons, neutrons and electrons for an element from the periodic table. They have also learned what the atomic mass is and what the mass number ends up being. The students just completed a quiz where they were able to demonstrate their understanding of interpreting the periodic table. We have also reviewed classification of matter which were outcomes from Science 8.  The students did a lab and they had to  classify matter as well as determine the probably identify of a substance. The questions for this lab are due on Monday. Next week we will be learning about chemical and physical properties and changes of substances.

Math:  Grade 9s are in the midst of working through Circle Geometry.  We have spent a week at looking at angles, chords and the Pythagorean Theorem.  Much of this area of study involves problem solving.  We should be wrapped up before spring break.  Therefore, students should be looking at a unit final prior to the break.

March 2-6

Math:  We have wrapped up Polynomials for the time being.  All concepts will be revisited at a later date in preparation for PATs.  As we make the stretch run before spring break, we would like to ease things up a bit.  We are moving into Circle Geometry which students should wrap up before the break.  Much of the circle geometry concepts involve concepts from past years that are applied to problem based situations.  To be most successful, students need to have a solid understanding of angles from grade six and seven and the Pythagorean Theorem from grade eight.

Science:  The students are starting into their fourth unit, Chemistry. Those students who were not at Bamfield started by exploring the periodic table with a project called, “Element Superhero”. This project will be due on Monday. We will be reviewing the periodic table for all students in more depth as we progress through this unit. We will exploring chemical and physical properties and changes next week.

Feb 15-19

Science:  The Grade 9s have finished the Space Unit. It culminated with a cumulative quiz and with watching The Martian. Next week, while the students are at Bamfield, the Grade 9s remaining behind will be working on an introduction to the periodic table project. We are going to be working on the chemistry unit for the next 6 weeks. This will be a very important unit for the students as is leads directly into the chemistry unit in Science 10.

Math:  Our Polynomials unit test will be coming up this week.  Time will be spent reviewing for the test before we write it.  For students who are gone to Bamfield, you will be writing upon your return.

For review of our latest concepts, multiplying and dividing of polynomials:

We are next going to be moving into Circle Geometry which will take us until Spring Break.

Feb 10-12

Math:  Grade 9s have completed the addition and subtraction of polynomials this week.  9-1 and 9-2 wrapped up multiplication as well.  Next week, although a short week, will be devoted to multiplication and division of polynomials.

Science:  The students have been investigating concepts related to space. Recently, they had a few homework checks as they had some independent tasks. There are four new homework checks that are now on PowerSchool. We have learned about the following concepts, planets, plotting star coordinates (azimuth, altitude), spectroscopy, the Doppler Effect, red shift and blue shift. Next week we will be learning about triangulation and the following week we will be watching “The Martian” as the students are required to learn about what would be required to live in space.

Feb 3-7

Science:  The Grade 9s have finished the electricity unit with a unit test last week. We have now started into Space Exploration. We learned about the planets, Canada’s space milestones and star coordinates. The students had three tasks that are all found on Google Drive to do. The first two were due on Thursday and the third is due on Monday. Next week we will use paper astrolabes and learn about three types of telescopes.

Math:  This past week, we began looking at like and unlike terms with polynomials.  Students found that when collecting the like terms, this was the same as adding the polynomials.  Some students ventured into subtraction while others will make the jump into subtraction and multiplication in the coming week.

If your student requires extra assistance in the concepts in which we have covered during the past week, watch these:

Jan 27-30

Math:  Grade 9s will be continuing to explore the world of polynomials in the coming week.  We have finished the introduction component and will begin to study the four basic operations of polynomials beginning with addition and subtraction.  Remember, there is always extra practice available to improve those skills…either on the website or talk to Ms. Chaudhary or Mr. Honish.

Science:  The students have finished the electricity unit. We will be having a unit test on Monday, January 27th . All of the course work is on Google Drive and is numbered in order of how we proceeded through the unit. There is a unit review on Google Drive that the students were given and had a class period to review.  We will be starting into the Space unit on Tuesday. 

Jan 20-24

Math:  We are finishing rational numbers this week!  Our unit test will be on Tuesday, January 21.  Grade 9s will then move into a new world of Polynomials.  To be best prepared for success with Polynomials, students should have a good grasp of addition and subtraction of integers as well as exponents from the fall.

Science:  The students were learning how to calculate power, efficiency and usage of electricity. They wrote a quiz on it this week. It is imperative that the students know how to manipulate formulas and how to apply them to solve problems in science. They will see this a lot in Science 10. Next week we will be finishing our electricity unit by exploring electrolytic cells. There will be a unit test on January 27th.

Jan 13-17

Science:  The students are working through learning about 4 more equations in science as well as practicing unit conversions. These are VERY IMPORTANT skills for future science classes. The students are encouraged to continue to practice these skills and to ask questions if they need clarification. We are learning about power, electricity and energy in the home. P=IV, P = E/t, kW*h and cost / kW*h and Effeciency = Eout/Ein x100 = ______ %. We have also been learning about energy conversion and will pick this up next week when we start learning about motors. Students can expect a quiz next week on the equations.

Math:  The grade 9s are coming off an excellent week where they dove into rational numbers.  They explored out to add, subtract, multiply and divide rationals.  Much of their success came from the remedial work that was done before the break involving the addition, subtraction, multiplication and division of fractions and integers.  Next week, we will clean up any loose ends from last week and move into order of operations involving rational numbers before concluding with a unit test at the beginning of the following week.

For additional practice involving rationals:

Jan 7-10

Math:  When the 9s return after break, they will be with their usual classes.  That’s right, the groupings are over.  At least, for now.  We will be moving on with our rational numbers unit.  Although Ms. Potts’ group has completed this, they will receive some enrichment work involving rationals.

Science:  The students finished their debates this past week. They were exploring the various viewpoints of multiple energy sources. We will resume learning about the Electricity unit in January. Students should review Ohm’s law and manipulating formulas during the break.

Dec 16-19

Math:  Grade 9s will continue in the current math groupings for at least the next week.  Ms. Potts’ groups will be utilizing their knowledge of rational numbers to work on composite surface area.  Ms. Chaudary’s and Mr. Honish’s groups will be finishing up multiplication and division of fractions before moving into the grade nine rational number portion.

Science:  The students are working on preparing opening statements for our pseudo-debate next week. They are investigating energy sources and have to research and prepare two arguments for their chose source. On Monday, they will collaborate with their group by combining their individual work. On Monday, they will also prepare a argument against the energy source they are up against. Their individual work will be assessed and is due on Monday. See Google Drive for task details. 

Dec 9-13

Math:  Grade 9s are continuing in their groups.  Ms. Chaudary and Mr. Honish have moved out of the addition and subtraction of fractions and have begun, and will continue, with multiplication and division of fractions.  This will lead both classes into work with rational numbers.  Ms. Potts’ group has completed the rational numbers portion and will utilize that knowledge on concepts such as surface area.

Science:  The Science 9 students have started to investigate manipulating formulas and are using Ohm’s Law to practice this skill. Being able to manipulate formulas is a very useful skill for their future science endeavours. It is imperative that the students keep practicing this skill and that they stay current with their work in this unit.  All work is found on Google Drive and if the students miss a school day, they are to check Google Drive for the missed work. Last week, the students wrote a quiz on current, voltage and resistance, circuits and charges. They also had to compare current, resistance and voltage to a water model. Please see Power School for assessment information. Next week will be working more on Ohm’s Law and the students can expect a quiz with this topic.

Dec 2-6

Math:  Grade 9s will be continuing their regrouping in math this coming week.  Ms. Potts’ groups will be progressing with operations involving rational numbers.  Mr. Honish and Ms. Chaudary’s groups will continue with operations involving fractions; once that foundation has been laid, they to will begin operations with rational numbers.  Once all groups have completed the rational number portion, we will return to our regular classes.

Science:  The students have started the electricity unit. Many were away skiing or at bandcamp. All missed work is found on Google Drive. Students are expected to be current with their work by Monday (excuse the pun). We will be moving on to investigate Ohm’s Law. The students will be learning their first equation in Science 9 and the skill of manipulating formulas. It is imperative that the students practice how to manipulate formulas as this will set them up for success in Science 10.

Nov 25-29

Math:  During the coming week, grade 9s will continue in their math focus groups.  Ms. Potts’ group will continue their exploration into rational numbers.  Ms. Chaudary’s and Mr. Honish’s groups will change their attention to refining the skills around fractions, especially addition and subtraction so that both groups will find greater success with rational numbers.  There is no set timeline for the duration of the focus groups, but we would anticipate going into the first or second week of December.

Science:  The students have finished the Biological Diversity unit. We had a unit test that was based on former PAT questions. The students also were assessed on their understanding of the impacts of gene engineering. The students gathered information from a podcast called “The Ethics of Gene Editing" and from the movie GATTACA. They had to state their position on if gene editing is acceptable in humans while supporting it with evidence. We will be moving into our Electricity unit next week.

Nov 18-21

Science:  The Grade 9s will have a unit test on Biodiversity on Tuesday, November 19th. They were given a review outline on Wednesday and will have time to review on Monday. They should work on filling this out over the weekend. On Monday, the students will also be given some review questions. We just finished watching GATTACA and discussing the ethics surrounding gene editing. The students will be having an in-class assessment on this starting on the 20th. They are able to bring their notes to this assessment as they will be writing about their position on gene editing in humans. 

Math:  This past week, grade 9 students were split into three groupings, led by Ms. Chaudary, Mr. Honish and Ms. Potts.  Groups were split according to the needs of those students identified on their rational number pre-assessment the previous week.  Each teacher has areas to focus on.  The smaller class size also allows for more individual time to work with your student.  In this way, we are able to assist students in improving their integer, fraction and number sense skills from previous grades to have greater success with the rational number component of grade 9.  Groupings are likely to last a couple of weeks, but may go longer if the need is necessary.

Nov 12-15

In Science, the students are finishing up the biology unit. We will be learning about gene editing technology by listening to a podcast on the subject. We will then take our understanding with us as we watch the film, GATTACA. We will be considering the societal impact of gene editing in humans. The students will culminate  the unit with a test on November 18.

In math this past week, the grade 9s completed a pre-assessment of rational numbers.  The purpose of this is to target areas of need during the upcoming week.  Students in 9-1 will combine with 9-3 while 9-2 will be with 9-4.  As a result, your student may be working with Ms. Chaudary, Mr. Honish or Ms. Potts, depending on their need.  Targeted needs include the addition and subtraction of integers, multiplication and division of integers, foundational fraction skills, addition and subtraction of fractions, and multiplication and division of fractions.  All of these pre-requisite skills are leading up to our study of rational numbers.  For additional support in these areas, see below:

Nov 4-8

Science:  We are learning about inheritance and genetic expression and the students will follow up with their lab activity this week.  We will then learn about the concepts Meiosis and Mitosis.  Expect an email regarding permission to view a movie on the topic of genetic engineering and society.  The unit test will be in mid November and students should review the new terminology on a regular basis.

Math:  Grade 9s will be entering rational numbers in math.  We will be going back this week to look at positive and negative numbers using all four basic operations.  In addition, grade 9s will look at the four basic operations involving fractions.  These are all concepts that were covered in grade 7 and 8.  Next week, we will be looking at combining these concepts into one.

October 28-31

Science:  The students in Grade 9 are moving into the section of the biodiversity unit that talks about inheritance. We will start to learn about DNA as a hereditary molecule.  The students finished notes on sexual and asexual reproduction and had a response question assessment. It is imperative that those students who do not finish work in class, do so at home. 

Math:  We are finishing up our Powers and Exponents unit in math next week.  All classes will be reviewing for a test at the beginning of the week.  Students should be aware of their test date, as different classes may have their test on different days.  Review material has also been shared on google.  Study hard this weekend! 

October 21-25

Math: grade 9s will continue with order of operations and exponent laws during the next week.  For additional practice at home, students can refer to the links provided during last week's math update.  Students should be expecting their next test to be sometime during the week of October 28.

Science:  The Grade 9s are watching a documentary on Monday (there was a permission to view email sent out). This documentary will address the following outcome:

Describe, in general terms, the role of genetic materials in the continuity and variation of species characteristics; and investigate and interpret related technologies

  • compare sexual and asexual reproduction, in terms of the advantages and disadvantages (e.g., recognize that asexual reproduction provides an efficient means of transmitting characteristics and that sexual reproduction provides an opportunity for recombination of characteristics)  

Students will be asked to respond to some related questions. We will then continue with our notes on asexual and sexual reproduction in organisms. This will then lead us into the  topic of inheritance where we still start to learn about genetics and DNA as a hereditary molecule.

October 15-18

Math:  During this week, we will begin to further investigate order of operations.  In the past, students have followed BEDMAS, without the evaluation of exponents.  But, now that we know how to evaluate an exponent, students will be able to evaluate any expression involving brackets, exponents and the four arithmetic operations.  In addition, we will also begin to look at exponent laws.  The exponent laws are very important for higher level math that follows in high school.

October 7-10

Science:  The students have completed the first section of the Biodiversity unit. They will be having a quiz on Monday. Information regarding the quiz can be found on their Google Drives. They also completed work on a graph the shows continuous variation. They had two class periods with some extra time to work on it. It is due on Monday as well. Information regarding the expectations of that task is also found on Google Drive.

Math:  Grade 9 math has moved fully into the world of BIG numbers and begun to study exponents.  We have looked at the parts of powers and the purpose of a power.  Next week, we will continue to study how to evaluate powers including order of operations involving exponents.  Eventually, we will look at how the exponent laws are used to simplify expressions.

September 30-October 4

Science:  The Grade 9 students have started their first unit: Biological Diversity.  We have covered the following concepts: Niche, competition and symbiosis. We have also been practicing our terminology. It is important that the students are reviewing the new vocab daily. 

Math: Grade 9s have wrapped up their data analysis this week and will be writing their unit final at the beginning of next week.  We will then be moving into exponents.  The concept of an exponent is mainly new for the students as they have not had much exposure in the past.  We really encourage practice, practice and practice with exponents because we are laying much of the foundation for high school mathematics.  Look back next week at the many websites that could be used to build understanding with exponents.

September 23-27

Math:  Now that the grade 9s have completed potential problems with surveys (the what to question and the how to ask the question), now we are going to look at where, when and who to survey.  This will explore different types of surveying techniques by exploring the strengths and weaknesses of each.  Students should be expecting a unit test on the material that we have covered during the week of September 30.

Science:  The students had a great time on the Bow River last week during their RiverWatch field trip. We will be starting into our first unit on Monday; Biodiversity. 

September 16-19

Science:  The students have been focusing on their understanding of the scientific method, building on the skills learned in Grade 8.  This week we will be working on data collection and making inferences and conclusions from graphs. We will also be preparing for our RiverWatch field trip, which is on September 19, 2019. Forms went home Friday.

Math:  This week, the grade 9s started with multiplication and MIPI testing so that Mr. Honish and Ms. Potts could get a clearer picture of where students were at in relation to their grade level.  Testing will be done throughout the year periodically to track student progress and continue to assist with their learning needs.

On Monday, students participated in a survey to gain information about their grade 9 farewell.  However, the survey was a hoax to educate the students that the way in which a question is written may impact the answer to our questions.  This has allowed us moved into the data analysis portion of our grade 9 program.  Students investigated 8 potential problems that could impact the results of a survey.  This included reworking a survey given my Ms. Terris and Ms. Dvorkin last week.  Grade 9s will continue with much the same next week.

September 9-13

Science:  The students in Science 9 started out the year with a design challenge. They worked in lab groups to create a table out of newspaper that would support as many books as possible. Before we delve into our first unit, the students can expect to learn about lab safety, WHMIS and practice skills related to the scientific method.

There will be a science field trip on September 19th called RiverWatch. The students will be floating down the Bow River learning about human impact on aquatic ecosystems. Stay tuned for more information and for the field trip forms! 

Math:  Ms. Potts and Mr. Honish are really looking forward to working with this wonderful group of students.  Ms. Potts brings nearly 20 years of math education to her classroom while Mr. Honish has 22 years; this being the 4th year for some your grade 9s.  We will have our google classrooms set up shortly where students an access the lessons we do on a daily basis.  Both Ms. Potts and Mr. Honish will be working together to make the math meaningful and challenging for your student.  This past week, both teachers introduced themselves on Wednesday and went through expectations and a fun addition game on Thursday.  In this upcoming week, students will be doing some baseline testing so that we can assess where your student is working in relation to grade level requirements.  This can also highlight areas in which the student is experiencing gaps in their learning.  As a result, we will spend some time each period devoted to basic skills.  During the first month, our focus will be on basic multiplication facts; any practice in this area at home would be welcomed.  As far as curriculum, grade 9s will begin the statistics portion of our year.  We will look at how the survey question is presented will influence our data.  Also, we will look at biases that affect survey questions. 

Next week, we will establish some math help times available to students; but they are encouraged to ask anytime they need some extra assistance.  To support your student at home, each week on this website, we post online support (this includes a short instructional video and online practice).  Once our google classroom is set up, there will be a textbook online and extra practice packages complete with explanations. 

Enjoy your weekend and students – be ready to do math next week!

September 4-6

WELCOME BACK!

Math and Science

June 15-19

Math:  Mock PAT Week is here!  During the coming week, there will not be new material.  Tuesday will be devoted to a practice Part A Math Provincial Achievement Test that students can access on D2L Quizzes.  This is the no calculator portion of the PAT.  This test is not the actual PAT.  Many students have asked to see what one would look like since they did not have the opportunity to write theirs.  Wednesday will be the Part B portion of the Math PAT.  This is a calculator multiple choice portion.  On D2L this past week, students can access packages of material that they did not cover due to COVID, if they wish.  As well, there is a no calculator test given by Joane Cardinal Schubert High School that informs grade 9 the concepts that they would need to know to increase their chance of success in Math 10C.  Good luck this week!

June 8-12

Math:  During the coming week, grade 9s will continue to investigate inequalities.  We will be graphing inequalities on a number line using the whole number and rational number systems.  Grade 9s will then move into solving inequalities in much the same form that they solved equations.  In a couple of weeks, grade 9s will be exposed to a practice Provincial Achievement test as many of the students have requested that they still have the opportunity to write a Math PAT via D2L.  

June 1-5

Math:  We will be wrapping up equation solving during the next week with a D2L quiz.  Students will then move into inequalities.  Inequalities are the less than and greater than that students learned at a very young age.  But, now, those two signs will now be used to solve inequalities, not equations, inequalities.  The process will be similar.  We anticipate that this concept will take us until mid-June.

Science:  

May 25-29

Math:  We will begin to wrap up equation solving over the next couple of weeks.  Grade 9s will receive a final review of equations next week.  Upon completion, they will be provided with the solutions to check their work before having a quiz the following week.

Science:  We will be talking about acids and bases. We will identify something as acidic, basic, or neutral based on its pH and look at the effects that acids and bases have on each other, on other substances and on living things.

May 19-22

Math:  During this upcoming week, grade 9s will continue to work with equation solving.  Because this skill is so necessary for high school, we will be spending a fair amount of time on it.  The only real difference between the equations in grade 9 compared to those in grade 8 is the complexity.  This year, we will be using a lot of negatives, decimals and fractions.  We will begin the week solving where students will receive the answer key so that they can check their own solutions.  Then, grade 9s will move into equation solving on their own.  Once their work has been submitted, they will receive an answer key to check their own work.  In the coming weeks, students will be submitting their work for feedback.  As always, if students are finding that they are not able to solve equations correctly, they are encouraged to tune into Google Meet sessions to troubleshoot their work.

Science:  We will be analyzing the data we collected from Riverwatch and determining how different factors of a river are connected. This data is one example of biological monitoring and can be used to make an informed decision on whether a body of water is healthy.


May 11-14

Math:  Whew…we have finished linear relations.  Looking at the quiz results coming in on D2L, you have done amazing, especially considering the fact that you are having to learn under a completely new platform.  We are going to spend some time moving into equation solving.  This is another concept that is so important for success in high school.  The procedures are the same as what students have experienced in grade 8, but now we have the wonderful privilege of using decimals, negatives and fractions in our equations.  Happy Solving during the coming week!

Science:  This week in Science we are looking at how chemicals enter organisms and what impacts some of these chemicals can have. We will then look at how toxins accumulate in food chains when they can’t be broken down by organisms.

May 4-8

Math:  This coming week, we will look at wrapping up linear relations.  We will spend a few days reviewing before completing a D2L quiz on linear relations at the end of the week.  We would then like to spend some time solving equations.  This is just a continuation of from grade eight.  Both linear relations and equation solving are quite important for success in high school.

Science:  This week we will be looking in more depth at organic and inorganic compounds and more specifically how our bodies use them.

April 27-May 1

Math:  During this past week, many of you have worked so hard with linear relations.  We will continue with much of the same during this coming week.  We will have continued exposure to these concepts so that nothing will come as a surprise.  This work will need to be submitted and will be checked carefully with feedback provided.

Science:  This week in Science we will be finishing off our Matter and Chemical Change unit talking about endothermic and exothermic reactions as well as factors that impact the rate of a reaction. We will also be starting our Environmental Chemistry unit with a look at organic and inorganic compounds.

April 20-24

Math:  So many grade 9s continue to have such amazing weeks with this temporary change in learning!!!  We are so impressed with you!

This past week, we have begun some work with linear relations.  Much of this is based on what students had done in grades 7 and 8.  We have revisited tables of values, equations and graphing.  We have decided that it would be beneficial for our grade 9s to cover these concepts to be better prepared for next year.  For the upcoming week, we will continue our work with linear relations.  We will explore the equations of horizontal and vertical lines as well as equations being written in a different from that we have been using.

Science:   Grade 9’s will be learning the types of chemical reactions. We will be building on our last two weeks of recognizing chemical formulas and using those to recognize which chemical reaction is occurring based on the reactants and products.

April 14-17

Science:   Monday is a PD day, so no lessons that day.  This week will be learning how to name Covalent Compounds and explore how this compares to Ionic Compounds.

Math:  During this week, grade 9s will finish their circle geometry with an online D2L quiz.  There are 14 questions that students will have the entire week to complete.  Please have it submitted by the end of the day on Friday (at which point, the quiz will close).  In addition, we will be moving forward with the beginning of linear relations.  Again, this will include two lessons that will involve reading through notes and examples and making your best effort on linear relation practice.

April 6-9

If parents want to see all of your child's courses, please use this link to learn how to log into D2L  (parents must log in as student to view full courses and content) https://www.youtube.com/watch?v=lNSVuKsFpbo&feature=youtu.be

Math:  We were working on Circle Geometry prior to our shut down and would like to pick up on the same.  We will spend the week (which is only 4 days) doing some review of circle geometry.  Ms. Chaudhary (with 9-1 and 9-2) and Mr. Honish (with 9-3 and 9-4) will be available online from 2-3 all four days for those that require assistance.  This is quite a learning experience for students and staff, so we appreciate all of the support you have offered so far, especially to your students.  Thanks so much!  Stay safe.

Science:  Ms. Mak will have posted information on the Science D2L shell for all grade 9 students.

March 31-April 3

Students have been sent an email instructing them to log into D2L.  A small assignment has been posted for students to complete this week.

March 23-30 SPRING BREAK

Teachers will be in contact with students and parents after Spring Break.

March 16-19

Math:  All classes are planning on wrapping up their Circle Geometry during the coming week.  Students should plan for their unit final during the week and having everything done before the spring break.

Science:  The students are working through the chemistry unit and have finished writing a quiz on trends in the periodic table. The quizzes have been marked and reviewed and students are able to do a “corrections quiz” if they would like to improve their understanding. Next week, we will be learning how to write a formal lab write up as well as doing a lab that involves exploring chemical and physical properties and changes. 

March 9-13

Science:  The students have learned how to find the protons, neutrons and electrons for an element from the periodic table. They have also learned what the atomic mass is and what the mass number ends up being. The students just completed a quiz where they were able to demonstrate their understanding of interpreting the periodic table. We have also reviewed classification of matter which were outcomes from Science 8.  The students did a lab and they had to  classify matter as well as determine the probably identify of a substance. The questions for this lab are due on Monday. Next week we will be learning about chemical and physical properties and changes of substances.

Math:  Grade 9s are in the midst of working through Circle Geometry.  We have spent a week at looking at angles, chords and the Pythagorean Theorem.  Much of this area of study involves problem solving.  We should be wrapped up before spring break.  Therefore, students should be looking at a unit final prior to the break.

March 2-6

Math:  We have wrapped up Polynomials for the time being.  All concepts will be revisited at a later date in preparation for PATs.  As we make the stretch run before spring break, we would like to ease things up a bit.  We are moving into Circle Geometry which students should wrap up before the break.  Much of the circle geometry concepts involve concepts from past years that are applied to problem based situations.  To be most successful, students need to have a solid understanding of angles from grade six and seven and the Pythagorean Theorem from grade eight.

Science:  The students are starting into their fourth unit, Chemistry. Those students who were not at Bamfield started by exploring the periodic table with a project called, “Element Superhero”. This project will be due on Monday. We will be reviewing the periodic table for all students in more depth as we progress through this unit. We will exploring chemical and physical properties and changes next week.

Feb 15-19

Science:  The Grade 9s have finished the Space Unit. It culminated with a cumulative quiz and with watching The Martian. Next week, while the students are at Bamfield, the Grade 9s remaining behind will be working on an introduction to the periodic table project. We are going to be working on the chemistry unit for the next 6 weeks. This will be a very important unit for the students as is leads directly into the chemistry unit in Science 10.

Math:  Our Polynomials unit test will be coming up this week.  Time will be spent reviewing for the test before we write it.  For students who are gone to Bamfield, you will be writing upon your return.

For review of our latest concepts, multiplying and dividing of polynomials:

We are next going to be moving into Circle Geometry which will take us until Spring Break.

Feb 10-12

Math:  Grade 9s have completed the addition and subtraction of polynomials this week.  9-1 and 9-2 wrapped up multiplication as well.  Next week, although a short week, will be devoted to multiplication and division of polynomials.

Science:  The students have been investigating concepts related to space. Recently, they had a few homework checks as they had some independent tasks. There are four new homework checks that are now on PowerSchool. We have learned about the following concepts, planets, plotting star coordinates (azimuth, altitude), spectroscopy, the Doppler Effect, red shift and blue shift. Next week we will be learning about triangulation and the following week we will be watching “The Martian” as the students are required to learn about what would be required to live in space.

Feb 3-7

Science:  The Grade 9s have finished the electricity unit with a unit test last week. We have now started into Space Exploration. We learned about the planets, Canada’s space milestones and star coordinates. The students had three tasks that are all found on Google Drive to do. The first two were due on Thursday and the third is due on Monday. Next week we will use paper astrolabes and learn about three types of telescopes.

Math:  This past week, we began looking at like and unlike terms with polynomials.  Students found that when collecting the like terms, this was the same as adding the polynomials.  Some students ventured into subtraction while others will make the jump into subtraction and multiplication in the coming week.

If your student requires extra assistance in the concepts in which we have covered during the past week, watch these:

Jan 27-30

Math:  Grade 9s will be continuing to explore the world of polynomials in the coming week.  We have finished the introduction component and will begin to study the four basic operations of polynomials beginning with addition and subtraction.  Remember, there is always extra practice available to improve those skills…either on the website or talk to Ms. Chaudhary or Mr. Honish.

Science:  The students have finished the electricity unit. We will be having a unit test on Monday, January 27th . All of the course work is on Google Drive and is numbered in order of how we proceeded through the unit. There is a unit review on Google Drive that the students were given and had a class period to review.  We will be starting into the Space unit on Tuesday. 

Jan 20-24

Math:  We are finishing rational numbers this week!  Our unit test will be on Tuesday, January 21.  Grade 9s will then move into a new world of Polynomials.  To be best prepared for success with Polynomials, students should have a good grasp of addition and subtraction of integers as well as exponents from the fall.

Science:  The students were learning how to calculate power, efficiency and usage of electricity. They wrote a quiz on it this week. It is imperative that the students know how to manipulate formulas and how to apply them to solve problems in science. They will see this a lot in Science 10. Next week we will be finishing our electricity unit by exploring electrolytic cells. There will be a unit test on January 27th.

Jan 13-17

Science:  The students are working through learning about 4 more equations in science as well as practicing unit conversions. These are VERY IMPORTANT skills for future science classes. The students are encouraged to continue to practice these skills and to ask questions if they need clarification. We are learning about power, electricity and energy in the home. P=IV, P = E/t, kW*h and cost / kW*h and Effeciency = Eout/Ein x100 = ______ %. We have also been learning about energy conversion and will pick this up next week when we start learning about motors. Students can expect a quiz next week on the equations.

Math:  The grade 9s are coming off an excellent week where they dove into rational numbers.  They explored out to add, subtract, multiply and divide rationals.  Much of their success came from the remedial work that was done before the break involving the addition, subtraction, multiplication and division of fractions and integers.  Next week, we will clean up any loose ends from last week and move into order of operations involving rational numbers before concluding with a unit test at the beginning of the following week.

For additional practice involving rationals:

Jan 7-10

Math:  When the 9s return after break, they will be with their usual classes.  That’s right, the groupings are over.  At least, for now.  We will be moving on with our rational numbers unit.  Although Ms. Potts’ group has completed this, they will receive some enrichment work involving rationals.

Science:  The students finished their debates this past week. They were exploring the various viewpoints of multiple energy sources. We will resume learning about the Electricity unit in January. Students should review Ohm’s law and manipulating formulas during the break.

Dec 16-19

Math:  Grade 9s will continue in the current math groupings for at least the next week.  Ms. Potts’ groups will be utilizing their knowledge of rational numbers to work on composite surface area.  Ms. Chaudary’s and Mr. Honish’s groups will be finishing up multiplication and division of fractions before moving into the grade nine rational number portion.

Science:  The students are working on preparing opening statements for our pseudo-debate next week. They are investigating energy sources and have to research and prepare two arguments for their chose source. On Monday, they will collaborate with their group by combining their individual work. On Monday, they will also prepare a argument against the energy source they are up against. Their individual work will be assessed and is due on Monday. See Google Drive for task details. 

Dec 9-13

Math:  Grade 9s are continuing in their groups.  Ms. Chaudary and Mr. Honish have moved out of the addition and subtraction of fractions and have begun, and will continue, with multiplication and division of fractions.  This will lead both classes into work with rational numbers.  Ms. Potts’ group has completed the rational numbers portion and will utilize that knowledge on concepts such as surface area.

Science:  The Science 9 students have started to investigate manipulating formulas and are using Ohm’s Law to practice this skill. Being able to manipulate formulas is a very useful skill for their future science endeavours. It is imperative that the students keep practicing this skill and that they stay current with their work in this unit.  All work is found on Google Drive and if the students miss a school day, they are to check Google Drive for the missed work. Last week, the students wrote a quiz on current, voltage and resistance, circuits and charges. They also had to compare current, resistance and voltage to a water model. Please see Power School for assessment information. Next week will be working more on Ohm’s Law and the students can expect a quiz with this topic.

Dec 2-6

Math:  Grade 9s will be continuing their regrouping in math this coming week.  Ms. Potts’ groups will be progressing with operations involving rational numbers.  Mr. Honish and Ms. Chaudary’s groups will continue with operations involving fractions; once that foundation has been laid, they to will begin operations with rational numbers.  Once all groups have completed the rational number portion, we will return to our regular classes.

Science:  The students have started the electricity unit. Many were away skiing or at bandcamp. All missed work is found on Google Drive. Students are expected to be current with their work by Monday (excuse the pun). We will be moving on to investigate Ohm’s Law. The students will be learning their first equation in Science 9 and the skill of manipulating formulas. It is imperative that the students practice how to manipulate formulas as this will set them up for success in Science 10.

Nov 25-29

Math:  During the coming week, grade 9s will continue in their math focus groups.  Ms. Potts’ group will continue their exploration into rational numbers.  Ms. Chaudary’s and Mr. Honish’s groups will change their attention to refining the skills around fractions, especially addition and subtraction so that both groups will find greater success with rational numbers.  There is no set timeline for the duration of the focus groups, but we would anticipate going into the first or second week of December.

Science:  The students have finished the Biological Diversity unit. We had a unit test that was based on former PAT questions. The students also were assessed on their understanding of the impacts of gene engineering. The students gathered information from a podcast called “The Ethics of Gene Editing" and from the movie GATTACA. They had to state their position on if gene editing is acceptable in humans while supporting it with evidence. We will be moving into our Electricity unit next week.

Nov 18-21

Science:  The Grade 9s will have a unit test on Biodiversity on Tuesday, November 19th. They were given a review outline on Wednesday and will have time to review on Monday. They should work on filling this out over the weekend. On Monday, the students will also be given some review questions. We just finished watching GATTACA and discussing the ethics surrounding gene editing. The students will be having an in-class assessment on this starting on the 20th. They are able to bring their notes to this assessment as they will be writing about their position on gene editing in humans. 

Math:  This past week, grade 9 students were split into three groupings, led by Ms. Chaudary, Mr. Honish and Ms. Potts.  Groups were split according to the needs of those students identified on their rational number pre-assessment the previous week.  Each teacher has areas to focus on.  The smaller class size also allows for more individual time to work with your student.  In this way, we are able to assist students in improving their integer, fraction and number sense skills from previous grades to have greater success with the rational number component of grade 9.  Groupings are likely to last a couple of weeks, but may go longer if the need is necessary.

Nov 12-15

In Science, the students are finishing up the biology unit. We will be learning about gene editing technology by listening to a podcast on the subject. We will then take our understanding with us as we watch the film, GATTACA. We will be considering the societal impact of gene editing in humans. The students will culminate  the unit with a test on November 18.

In math this past week, the grade 9s completed a pre-assessment of rational numbers.  The purpose of this is to target areas of need during the upcoming week.  Students in 9-1 will combine with 9-3 while 9-2 will be with 9-4.  As a result, your student may be working with Ms. Chaudary, Mr. Honish or Ms. Potts, depending on their need.  Targeted needs include the addition and subtraction of integers, multiplication and division of integers, foundational fraction skills, addition and subtraction of fractions, and multiplication and division of fractions.  All of these pre-requisite skills are leading up to our study of rational numbers.  For additional support in these areas, see below:

Nov 4-8

Science:  We are learning about inheritance and genetic expression and the students will follow up with their lab activity this week.  We will then learn about the concepts Meiosis and Mitosis.  Expect an email regarding permission to view a movie on the topic of genetic engineering and society.  The unit test will be in mid November and students should review the new terminology on a regular basis.

Math:  Grade 9s will be entering rational numbers in math.  We will be going back this week to look at positive and negative numbers using all four basic operations.  In addition, grade 9s will look at the four basic operations involving fractions.  These are all concepts that were covered in grade 7 and 8.  Next week, we will be looking at combining these concepts into one.

October 28-31

Science:  The students in Grade 9 are moving into the section of the biodiversity unit that talks about inheritance. We will start to learn about DNA as a hereditary molecule.  The students finished notes on sexual and asexual reproduction and had a response question assessment. It is imperative that those students who do not finish work in class, do so at home. 

Math:  We are finishing up our Powers and Exponents unit in math next week.  All classes will be reviewing for a test at the beginning of the week.  Students should be aware of their test date, as different classes may have their test on different days.  Review material has also been shared on google.  Study hard this weekend! 

October 21-25

Math: grade 9s will continue with order of operations and exponent laws during the next week.  For additional practice at home, students can refer to the links provided during last week's math update.  Students should be expecting their next test to be sometime during the week of October 28.

Science:  The Grade 9s are watching a documentary on Monday (there was a permission to view email sent out). This documentary will address the following outcome:

Describe, in general terms, the role of genetic materials in the continuity and variation of species characteristics; and investigate and interpret related technologies

  • compare sexual and asexual reproduction, in terms of the advantages and disadvantages (e.g., recognize that asexual reproduction provides an efficient means of transmitting characteristics and that sexual reproduction provides an opportunity for recombination of characteristics)  

Students will be asked to respond to some related questions. We will then continue with our notes on asexual and sexual reproduction in organisms. This will then lead us into the  topic of inheritance where we still start to learn about genetics and DNA as a hereditary molecule.

October 15-18

Math:  During this week, we will begin to further investigate order of operations.  In the past, students have followed BEDMAS, without the evaluation of exponents.  But, now that we know how to evaluate an exponent, students will be able to evaluate any expression involving brackets, exponents and the four arithmetic operations.  In addition, we will also begin to look at exponent laws.  The exponent laws are very important for higher level math that follows in high school.

October 7-10

Science:  The students have completed the first section of the Biodiversity unit. They will be having a quiz on Monday. Information regarding the quiz can be found on their Google Drives. They also completed work on a graph the shows continuous variation. They had two class periods with some extra time to work on it. It is due on Monday as well. Information regarding the expectations of that task is also found on Google Drive.

Math:  Grade 9 math has moved fully into the world of BIG numbers and begun to study exponents.  We have looked at the parts of powers and the purpose of a power.  Next week, we will continue to study how to evaluate powers including order of operations involving exponents.  Eventually, we will look at how the exponent laws are used to simplify expressions.

September 30-October 4

Science:  The Grade 9 students have started their first unit: Biological Diversity.  We have covered the following concepts: Niche, competition and symbiosis. We have also been practicing our terminology. It is important that the students are reviewing the new vocab daily. 

Math: Grade 9s have wrapped up their data analysis this week and will be writing their unit final at the beginning of next week.  We will then be moving into exponents.  The concept of an exponent is mainly new for the students as they have not had much exposure in the past.  We really encourage practice, practice and practice with exponents because we are laying much of the foundation for high school mathematics.  Look back next week at the many websites that could be used to build understanding with exponents.

September 23-27

Math:  Now that the grade 9s have completed potential problems with surveys (the what to question and the how to ask the question), now we are going to look at where, when and who to survey.  This will explore different types of surveying techniques by exploring the strengths and weaknesses of each.  Students should be expecting a unit test on the material that we have covered during the week of September 30.

Science:  The students had a great time on the Bow River last week during their RiverWatch field trip. We will be starting into our first unit on Monday; Biodiversity. 

September 16-19

Science:  The students have been focusing on their understanding of the scientific method, building on the skills learned in Grade 8.  This week we will be working on data collection and making inferences and conclusions from graphs. We will also be preparing for our RiverWatch field trip, which is on September 19, 2019. Forms went home Friday.

Math:  This week, the grade 9s started with multiplication and MIPI testing so that Mr. Honish and Ms. Potts could get a clearer picture of where students were at in relation to their grade level.  Testing will be done throughout the year periodically to track student progress and continue to assist with their learning needs.

On Monday, students participated in a survey to gain information about their grade 9 farewell.  However, the survey was a hoax to educate the students that the way in which a question is written may impact the answer to our questions.  This has allowed us moved into the data analysis portion of our grade 9 program.  Students investigated 8 potential problems that could impact the results of a survey.  This included reworking a survey given my Ms. Terris and Ms. Dvorkin last week.  Grade 9s will continue with much the same next week.

Science:  The students in Science 9 started out the year with a design challenge. They worked in lab groups to create a table out of newspaper that would support as many books as possible. Before we delve into our first unit, the students can expect to learn about lab safety, WHMIS and practice skills related to the scientific method.

There will be a science field trip on September 19th called RiverWatch. The students will be floating down the Bow River learning about human impact on aquatic ecosystems. Stay tuned for more information and for the field trip forms! 

Math:  Ms. Potts and Mr. Honish are really looking forward to working with this wonderful group of students.  Ms. Potts brings nearly 20 years of math education to her classroom while Mr. Honish has 22 years; this being the 4th year for some your grade 9s.  We will have our google classrooms set up shortly where students an access the lessons we do on a daily basis.  Both Ms. Potts and Mr. Honish will be working together to make the math meaningful and challenging for your student.  This past week, both teachers introduced themselves on Wednesday and went through expectations and a fun addition game on Thursday.  In this upcoming week, students will be doing some baseline testing so that we can assess where your student is working in relation to grade level requirements.  This can also highlight areas in which the student is experiencing gaps in their learning.  As a result, we will spend some time each period devoted to basic skills.  During the first month, our focus will be on basic multiplication facts; any practice in this area at home would be welcomed.  As far as curriculum, grade 9s will begin the statistics portion of our year.  We will look at how the survey question is presented will influence our data.  Also, we will look at biases that affect survey questions. 

Next week, we will establish some math help times available to students; but they are encouraged to ask anytime they need some extra assistance.  To support your student at home, each week on this website, we post online support (this includes a short instructional video and online practice).  Once our google classroom is set up, there will be a textbook online and extra practice packages complete with explanations. 

Enjoy your weekend and students – be ready to do math next week!

September 4-6
