Today, we started our Alka Seltzer Rocket lab. We took old film canisters, and filled them up with different levels of water, and tablets of Alka Seltzer. We had a control group, which was having the canister half full of water. And in our other tests, we had different levels of water, and we would see if the rocket shot higher, or lower. Basically, this lab was teaching us to understand The independent and dependent variables.
