Week 13 & 14

Week 13 & 14

I've been pretty busy the last week so I didn't get a chance to post. So this week I have posted for both week 13 and 14.

Math 9

We are moving on to Linear Algebra.  Last week, we learned about domain and range of a graph as well as slope-intercept form, which is y=mx+b.  We have learned that slope (m) is equal to rise (up if positive and down if negative) over run (to the right) and the point where the equation touches the y axis is b (otherwise known as the y-intercept).

This week we are learning how to find the slope and equation if only given two coordinates as well as how to plot a graph if the equation is in point-slope form.  We will also try to find the intersection of two equations as well as be able to find equations that are parallel and perpendicular to each other.  We will also learn about inequalities and addition/elimination techniques.

We will have a test on December 11, 2014 on Linear Algebra.  We will then start our project on Bill Nye the Math Guy which is due December 18, 2014.  We will have a Christmas Fun Day on December 19, 2014 before the Christmas Banquet.


Science 8

We are beginning a new unit on Vision and Optics.  We are learning about light and how it can be blocked, reflected and refracted.

We will be starting a project called the Bill Nye the Science Guy Project on December 5 (8B) and December 8 (8A).  The students will be required to create a Bill Nye video that they will share with the class on December 17 (8B) and December 18 (8A).  We will be having a Christmas Fun Period on December 19, 2014 (8B).


Science 7

We are still learning about Matter and have started a new project where students are creating a Bill Nye the Science Guy video.  The assignment will be due December 10, 2014.  The students will present the videos they have created on that date.  We will then finish up our notes on Matter and have a Christmas Fun Day on December 18, 2014.
