Last week, to continue with our Rockets Liftoff activities, 4th grade went outside to create and test some of their own rockets. We split into teams to fill a film canister with different combinations of Alka-Seltzer, corn starch, and water. We hypothesized, then tested which combinations we thought would shoot the rocket highest into the air. After multiple experiments and tests, we concluded that using less of each ingredient would actually make the rocket shoot higher because there was more room for the gases to build up and explode! Successful and fun day!
