Only a couple of days updated at the moment as we will see how the week goes! Monday We will review Powers, exponents, and bases first and then will look at Base 10 and Exponent Zero Concepts. For those absent, read and perform the activities on Pages 58 and 59 to make sure we understand these concepts. Pages 61-62 questions. In Science, we will talk about the octet rule for electrons and will draw the Bohr diagrams for the first 20 elements. For this, remember: Proton number and electron number (in atoms) is equal to the atomic number. Neutron number is equal to the atomic mass (rounded to the closest whole number) - atomic number. In a Bohr diagram, we draw the nucleus first (a circle) with the number of protons and neutrons written inside. We then fill in the electrons from the inside orbital out with a maximum of 2 electrons in the first orbital, 8 in the second, 8 in the third, and 2 in the fourth (we only go up to calcium). Below is an example of phosphorus. On Tuesday, we will write a quiz for topics 1-5 in Chemistry. The notes (in addition to what has been done in class) were posted on this blog.

This week, on Wednesday, the councillors from Crescent Heights High School will come in to register our students in classes in the afternoon. We have been talking to you about whether you want: Semesterized courses Full Year Courses IB or AP Science Stream For additional information on the options, please visit the Crescent Heights website. ScienceThis week in science, we will be talking about the construction of the periodic table, the makeup of elements, and the laws of definite composition and conservation of mass. The notes for this unit (up to the end of the week) are roughly paraphrased below. We will have a quiz at the start of next week about topics 1-5 (the notes below).
Have time for a quick (and different video than in class) video about the periodic table? Check out the youtube video below. MathWe have worked through enlargements, reductions, Scale Factor, and Transformations (flips, slides, and rotations) in the last month. To finish it off, we are working on the design your own flag assignment found below. Tentatively the due date is Wednesday.
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.
Welcome back everyone! I hope that the holiday season was awesome and that you are ready to hop back into the swing of things.
Heading into January, we will be starting our Matter and Chemical Change Unit. For the first week, that means looking at WHMIS (as a review), Particle Theory, Mixtures (homogeneous and heterogeneous), and some of the evolving theories of matter. In math, we will review our scale factor and similarity concepts before launching into transformations (flips, slides and rotations) and symmetry. http://provincialcouncils.ca/whmisgame/ |
