We decided to find out!  We measured everyone’s height   
And foot length

 
And tracked the data in a chart

  
We will make a scatter plot to interpret the trend in our class.

Each triangle has a simplified, or unsimplified expression.  The challenge is to match them all up!   
 
  

 We are experimenting with germination.  We’re putting beans in moist paper towel, and leaving the baggies on the windowsill for a week.  We will calculate the percent of beans that sprout.  
   
  

We experimented with the reactivity trends in the periodic table, comparing two elements in the same period, and two in the same group.

We saw that a gas was produced, so we captured and tested the gas.

The remaining liquid was no longer a neutral pH.

We had reacted calcium with water and produced hydrogen gas (we heard the “pop”) and calcium hydroxide (it’s a base).
  

  We used bunsen burners to conduct a flame test.  We tested copper sulfate and sodium sulfate and observed that the flames are different colours.

  The “sulfate” is the same in both chemicals so we could infer that the copper and sodium were what contributed to the colours.

We experimented with making bouncy balls out of white glue and a borax solution   
We learned what happens if you use too much or too little borax.   

  
We used a variety of candies to represent atoms, and we used toothpicks to represent pairs of shared electrons. 

 In chemistry we look for trends and patterns and use that to make predictions about other things.  In this game, there are 20 different aliens, but each group gets only 19 cards and uses their patterning skills to predict the missing piece.  
 

We looked at the different rectangles that can be created with the same perimeter (the length of a standard pipe cleaner).  We calculated the area for each rectangle.  We then experimented with calculating the rectangle with the biggest area and the smallest area using the same perimeter.
