**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 27^{th}.

**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.

**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 19**^{th}. 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 20^{th}. 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 19 ^{th}**

**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 4^{th} 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!

Exponent properties with quotients Learn how to simplify expressions like (5^6)/(5^2). Also learn how 1/(a^b) is the same as a^-b. Towards the end of the video, we practice simplifying more complex expressions like (25 * x * y^6)/(20 * y^5 * x^2). |

Exponent properties with parentheses Learn two exponent properties: (ab)^c and (a^b)^c. See WHY they work and HOW to use them. |

Worked example: Exponent properties Use exponent properties to simplify a challenging expression. |

Exponent properties 3 (video) | Khan Academy Simplify x to the third, and then that raised to the fourth power times x squared, and then that raised to the fifth power. Now, here we're going to use the power property of exponents, sometimes called the "power rule." And that just tells us if I have x to the a, and then I raise that to b-th ... |

Exponent Properties 2 |

Exponent properties 1 (video) | Khan Academy Simplify 3a times a to the fifth times a squared. So the exponent property we can use here is if we have the same base, in this case, it's a. If we have it raised to the x power, we're multiplying it by a to the y power, then this is just going to be equal to a to the x plus y power. And we'll think ... |

Try these for practice with exponent laws:

Powers of products & quotients Rewrite powers of products and quotients. For example, (3⁵⋅x³)² can be written as 3¹⁰⋅x⁶. |

Powers of products & quotients (structured practice) Rewrite expressions that involve powers of products and quotients. Expressions are in ascending difficulty. |

Rewrite quotients of powers with the same base. For example, (x⁵)/(x²) can be written as x³. |

Rewrite powers of powers. For example, (x²)⁵ can be written as x¹⁰. |

Rewrite products of powers with the same base. For example, x²⋅x⁵ can be written as x⁷. |

**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.

Online support videos can be found at:

Powers of zero (video) | Exponents | Khan Academy Any non-zero number to the zero power equals one. Zero to any positive exponent equals zero. So, what happens when you have zero to the zero power? |

1 and -1 to different powers (video) | Khan Academy Let's think about exponents with ones and zeroes. So let's take the number 1, and let's raise it to the eighth power. So we've already seen that there's two ways of thinking about this. |

Discover a pattern that explains why any non-zero number to the zero power equals one. |

**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 19 ^{th}**

**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 4^{th} 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**
