We hope to see many of you at interviews online!!!


November 15 - 19

Science: We have now reached the end of our Biological Diversity unit, and students will be writing their unit test early this week. From here, we'll move on to begin our Space Exploration unit.

Math: During the week of November 15, grade 9s will begin work with completing an error analysis for our Square Roots of Rational Numbers Test from the previous week.  We will then move into a pre-assessment for Linear Relations.  Concepts in this area are merely an extension of what students covered in grade 8.  We will begin by creating equations and expressions from t-tables as well as the relationships between the t-table, equation, problem and graph.


November 8 - 12

Science: This week, students will start to look at human impacts on biodiversity, as well as some strategies that have been employed to reduce loss of biodiversity at a local and global level.

Math: Grade 9s will be finishing up their work with square roots.  Students can prepare by looking over the previous assignments.  Expect the final test to be this coming week of November 8.  There will also be time given for the post-assessment.  Study hard this weekend!

November 1 - 5

Science: Now that students have spent some time learning about heritable traits and how they can be passed from generation to generation, we will put this knowledge to practice with some lab activities. Please see D2L for specific information regarding assignments and important dates.

Math:

This past week we began square roots.  During the upcoming week, Grade 9s will continue their work with square roots of perfect squares (including decimals and fractions) as well as estimating square roots of non-perfect squares (including decimals and square roots).

October 25 - 29

Science: This week, we'll continue to explore genetics and explore mitosis and meiosis. We'll look at the relationship between DNA, genes, and chromosomes, and talk about how traits can be passed from generation to generation.

October 19 - 22

Science: This week, we will start to move into the genetics portion of our biodiversity unit. Students will learn about how different heritable traits can be passed through generations, and we will move towards our Dragon Genetics Lab which will put some of this theory into practice. 

Math: During this shortened week, grade 9s will be finishing up their work with Powers and Exponents.  This will involve a final test and the post assessment to gauge the student’s growth.  We will then be moving into square roots.  Again, at the beginning of any new concept, we will complete a pre assessment to gauge each student’s progress and establish the student’s baseline.

October 12 - 15

Science: This week, we will look at variation as it related to sexual and asexual reproduction. We will begin to look at heritable and non-heritable traits, which will set us up to get into the genetics portion of the unit over the coming weeks.

Math: 

Students will be continuing to work through the second set of Exponent Laws.  Once complete, students should be expecting their final quiz/test which will cover the exponent laws.  To finish each unit, we will complete the post-assessment to gauge the growth students have made since they wrote the pre-assessment.  For additional support or practice:

October 4 - 8

Science:

This week, we'll complete our "Best Beak Physique" lab where we will simulate different beak shapes to see how well they pick up different types of food. 

Math:

During the coming week, we will be exploring the Exponent Laws.  These 5 make up a lot of foundational understanding for math in higher grades.  The week after Thanksgiving will bring the end of our work with Powers and Exponents, so look for the unit final at that time.

Have a wonderful week!

September 27 - October 1

Science:

This week, we'll continue to talk about adaptations, as well as intraspecies and interspecies variation. We'll also look at niches and resource partitioning. From there, we'll move towards our "Best Beak Physique" lab where we'll simulate different beak shapes to see how well they pick up different parts of food. This allows us to cover some concepts, as well as graph and analyze data which is something we want to focus on this year with the kids.

Math:

For those classes that have not yet completed their first exponents quiz, it will be coming up this week.  This quiz covers the meaning of a power, identifying parts of a power, evaluating powers including using order of operations.  After completing this, grade 9s will begin to look at the exponent laws.  These concepts are foundational skills for success in high school math.


September 20 - 24

Science:

Now that we've spent the last couple weeks talking about key scientific concepts and reviewing skills like interpreting data and graphing, it's time to begin our Biological Diversity unit. We'll start by looking at variation and how adaptations can help organisms in various environments and situations, as well as talking about how various species depend on each other for survival.

Math:

During the coming week, grade 9 math students will continue their work with powers and exponents.  Most of our time will be spent evaluating exponents.  Expect our first quiz of the year around mid-week.  Students will also begin to use the order of operations using exponents.  For additional practice with these concepts,

September 13 - 17

Science:
This week, we will be exploring the scientific method. We'll have discussions about Science as a method of thinking, and flow into testable questions, hypotheses, and procedure within experiments. We will also look at data analysis and which graphing methods are appropriate in different scenarios.

Math:

Welcome to Grade 9 Math!!!  After a couple of months off, your teachers are looking forward to getting back to some math concepts to get the brain working.  This past week, much of our time was spent getting some testing out of the way.  Testing will be done at various times throughout the year to gauge student learning.  We completed the MIPI (Mathematics Intervention Programming Instrument) to have a baseline as to where the student is at coming into grade 9.  As well, we completed a pre-assessment for Powers and Exponents – the first area of study this year.  We then investigated the meaning of a power.

In the coming week, grade 9s will continue their work with the purpose and evaluating powers.  It will be important to identify bases, exponents and coefficients. 

Extra help website will be found at this page from time to time.  For extra support with exponents thus far:

September 7 - 10

Science:
This week, we are learning about lab safety and WHMIS, and will be completing a fun "Lab Safety Meme" computer task that will allow students to bring some creativity to what they've learned.
