All you need are two tennis balls per group, one meter stick per group and something to keep the tennis balls cold like a cooler or freezer. The data really shows the difference between the bounce of a cold tennis ball and a room temperature ball. As a result, the data and the graph look great because a cold tennis ball will not bounce as a high as a room temperature tennis ball and it helps the kids understand how variables and controls work in a scientific investigation.
It’s good to show the Prezi link I provide before or after to help the kids understand Scientific method, Experimental design, Controlled variables, independent and dependent variables, manipulated and responding variables. It’s great for your 1st or 2nd lab of the year.
I added an extension as extra credit for kids to relate to the lab. If you’re not familiar with Tom Brady (the quarterback of the New England Patriots) and “Deflategate” it’s OK. There is information all over the internet and kids that had never heard of it were able to easily find the information and receive the extra credit.
