Red is positive and blue is negative… We explored what adding and subtracting integers looks like with algetiles. 

 We are using licorice laces to explore circles.  We measure the length and the diameter of the circle we can make  
It’s hard to make an exact circle.

 
We ate some of the licorice, then made a smaller circle, and tried again.  We collected the data in a table of values, and made a scatter plot of the data.

Divisibility rules are important tools to use when simplifying fractions.

We wrote the divisibility rules behind doors in an interactive notebook page.  
These pages can be used as a resource or a review tool later on.

 
We’re able to simplify big fractions without calculators now!

 We used an interesting visualization tool called “Elements 4D”.  We cut out patterns to make cubes.  Each side has a different element on it.  
 After downloading the app, we can look at the cube via the smartphone screen, and see what the element looks like.

  
The block can be rotated to view information about the element, and to get a better view.  Metals are all shiny, phosphorus is red, we learned lots!

  
Another neat feature of he app is that two cubes can be put together and if a compound will be formed, the compound and formula will be shown on the screen

Next week we will be looking at atoms and reviewing how compounds form.

Today Elena came to visit again to tell us about aerospace engineering.  

  
We talked about gravity and acceleration, and about projectiles thrown at an initial angle, and how trigonometry is used to determine horizontal and vertical components of velocity.

We then had a challenge, to make paper airplanes that flew the farthest. 

  
We had lots of different designs.

   
    
 
The paper ball ended up going the farthest.  We saw how air resistance can make a big difference!

Elena came to show us about civil engineering today.  We talked about strength, atability, and the distribution of forces.  Our challenge was to build a tower using paper and elastics to support the biggest load.   

   
We ran out of textbooks for this tower!

  
We looked at long answer EQAO questions today.  We worked on a question, and then we looked at the scoring guide to see how we did.  We also looked at samples of other student work provided by EQAO and tried to mark that.  It’s harder than we imagined.

We write the EQAO test on Tuesday and Wednesday next week.
