Following our Starchaser day we investigated balloon rocket boosters. We imagined that we were rocket scientists and our task was to investigate the best rocket booster, using balloons for the air propulsion.
We worked in teams and investigated a question of our choice eg. Which shape of balloon makes the best booster? Which size of balloon makes the best booster? Which method of fastening the balloon makes the best booster? To make our tests fair, we only changed one variable in each investigation. It was great fun testing!
