We just started the circle geometry unit in Math and this unit is relatively short (only 3 sections). Students are having a quiz on Section 8.1 and 8.2 next Wednesday.

MathStudents wrote the Polynomials unit test and got their tests back before the break. We are starting the Surface Area unit. So far, we reviewed surface area of a cube, a rectangular prism, a triangular prism, and a cylinder. We revisited Section 1.1 Perfect Squares that was a part of the Polynomials unit. Practice questions will come from the textbook as well as worksheets. Later this week, we will be starting the "Tin Man" project. I will explain the project in class and hand out the project outline, rubric, and reflection. Please start bringing in recyclables such as cardboard boxes to construct your tin man. MMS 9 Unit 1: Surface Area
ScienceEnvironmental Research ProjectStudents started the environmental research project on Tuesday before the break and we are half way through the group presentations. Last week, students continued to work on their group research project and half of the class (9A and 9E) presented at the end week. For students who are presenting on Monday, make sure you complete your peer evaluation form ( if you're in a group of 2 or 3) and have your presentation ready to go. And don't forget to email or share your presentation with me. PPM and Vanier River WorksheetsWe went over these two worksheets that I handed out before the spring break. Students that were away on the BGS field trip, make sure to grab the answers from your peer or come and see me in class. The Lorax Business LetterPlease make sure you hand in your business letter that was due on Friday (9A). 9E will get time to work on the business letter after the research presentations on Monday. 9E wil hand in the assignment to Ms.Ng. Where are we at?In Environmental Chemistry, we have Topic 6: Monitoring Air Quality to cover. This week we will be investigating air quality in Calgary and watch "An Inconvenient Truth" documentary.
MathWe just started the polynomials unit. We covered modeling using algebra tiles and simplifying polynomials. Next week we will be looking at adding and subtracting polynomials. Practice questions are assigned from the textbook. See below for Unit 5: Polynomials pdf version.
ScienceWe looked at balancing synthesis chemical equations. Students will have a quick quiz on reaction rate and a lab tomorrow. We will be doing a conservation of mass lab next week and start to wrap up the unit.
Ms. SritrakulAs many parents know (and hopefully all students!) I have been covering in the office since Mrs. Derbyshire has moved over to Robert Thirsk High school. In this time, we have tried to have substitute teachers in for stretches of time to gain consistency but I am now really excited that we have gotten Ms. Sritrakul to join our team for the remainder of our Chemistry Unit and beyond. Welcome Ms. Sritrakul! Field Trip FormsStudents have been given forms for Theatre Calgary and an intention form for Biogeosciences. If you have not yet returned the Theatre Calgary form, please do so. For Biogeosciences, the trip paperwork will come home to those that have paid the deposit or indicated their intent to attend the trip. This will happen over the next few weeks. In the interim, please ensure that the deposit has been sent in to the school or that we have received an indication that you are going to attend. There will be paperwork coming home for the Calgary Hitmen game that the school is going to attend at the end of February. The entire school is going to this event and the school has been given permission to shut down for the time that we are gone! This is a major event so please ensure that paperwork is returned promptly when it arrives home. Chemistry Anyone?
Powers and Exponent LawsWe are now over 1 week in to our powers and exponent laws unit and have gone through what a power is, base 10's and powers of 0, and the order of operations with powers. We will be discussing exponent laws next followed by perfect squares and square roots. Topics 1-3 of the attached textbook chapter have been covered and the next steps involve topics 4-6.
Mathematics This past week, we worked on reviewing some of the concepts from our scale factor and enlargements and reductions unit. This was capped off by an assignment (that says unit exam) for the concepts. This assignment was based on past PAT questions and is due on Monday. For class 9A, we also started on reflectional symmetry and had a textbook assignment (pages 357-359) that we were to complete. 9E will take these notes and work on this early in the week between January 15-19. This week, we will look at rotational symmetry and order of rotation (How many times does a shape line up with itself when rotated a full 360 degrees? For each time it lines up, we increase it's order of rotation by 1. A shape that only overlaps after a full rotation is said to have no rotational symmetry (you can never have an order of rotation of 1)). We will also have a quiz on Thursday about symmetry and flips, slides, and rotations. Science To start the term, we reviewed mixtures (homogeneous and heterogeneous) with the class. We also outlined what a chemical and physical reaction are. We will perform a demo a day to determine if we have mastered what each thing is. This will be done for 10 days and will count as a quiz. To cap off the week, we worked on the history of the atom and atoms, compounds, and molecules. The Paper atoms, compounds, and molecules sheet is due on Monday. With the history of the atom, we are working on putting the history down in a creative way (memes, poems, tweets, texts, etc.) and will be presenting these on Tuesday. We will also be looking at the law of conservation of mass and the periodic table in the coming days. For the law of conservation of mass, we will need pop bottle (600 mL) with the caps. Anyone that has some of these, please bring them in.
Rational numbers is not finished! For that matter, no unit in math is ever finished as the concepts build upon each other. But, as we move forward in math, we are going to start to look at linear relations and graphing. To start with, this week we are going to look at deriving patterns from data. My son, who is now in grade 4, has looked for patterns for years and we are going to be no different. That said, our patterns will be numeric based and we are going to try and find short cuts to skip pattern numbers.
The file above, on the left, provides extra practice problems as well as some exemplars and skeleton notes. On the right is a copy of our textbook chapter as a reference.
As we move forward in math, we will quickly draw to an end on our rational numbers unit. This includes looking at what a rational number is, adding and subtracting rational numbers, multiplying and dividing rational numbers, and finally the order of operations. Throughout this entire unit, having and being able to utilize a calculator are key. If you do not have one, please make sure that you get and bring one in soon.
As a reference to where we are, students can go through work from pages 127-128 (multiplication) from the textbook chapter posted above.
