The Balloon Experiment
On Friday we became Scientists and used our thinking skills to answer a question using these materials: string, rocket on a straw, balloon, and tape. The question was: “How can the balloon move up the string?” We came up with an hypotheses before we carried out our experiment to test our thinking. In our groups we worked together to test our hypotheses – we needed to repeat our experiment over and over and try new ideas as we observed what was happening. We decided the balloon needed to be in a place where the ‘air’ could escape and cause the balloon to move.
