January 23

Announcements:

  • No School Friday, January 31st

  • I hope today's wrestling meet was successful for those who attended!!!

Math: 

We are working on solving percent problems using the unit square.

A unit square has 100 squares and represents 100% as well as a whole (which could be anything: a pizza, 27 students, ...)
In the example below the whole is 400 people.

Note: When using the unit square always write the whole at the top & always solve for one percent or one small square.

One small square represents 1%.
In the case of 400 people, 1% of 400 is 4 (400/100 = 4).

Example Problem:
1.    Let the unit square represent 400 people. Write this as a title above the unit square.
a.    what does 1 small square represent? Colour in one square (1%) and write in the number of people this represents.


Are you able to figure out the next three questions with the information in the photo above?
b.    what do 5 small squares represent? 
c.    what do 20 small squares represent?  
d.    what part of the unit square would represent 100 people? 40 people? 120 people?  

***Please make sure if you missed today's class that you come see Ms. Bowen or Ms. Schneider!!!

Science:

*** Please hand in your Earth Layers assignment ASAP if you have not already done so!!!
Note: It was due on Thursday, January 23rd

In the next few classes we will be studying the theories of Continental Drift and Plate Tectonics.

A very important scientist, Alfred Wegener, is responsible for much of this understanding. He developed the theory of Continental Drift. To learn more about Continental Drift watch Continental Drift 101 and Plate Tectonics
Questions to Consider:
  • What is the name of the supercontinent shown in the before image above?
  • What evidence is there for the theory of Continental Drift?


The theory of Plate Tectonics describes the movement of the tectonic plates.

  • What happens at convergent, divergent and transform boundaries








For another short explanation of Plate Tectonics watch Plate Tectonics Explained
