To further investigate force, Mrs. Kochis' class was challenged to design and build a balloon rocket. We discussed what would happen to the blown up balloon if I let go of it without tying it off. The students had many hypothesis'. My favorite was that it would explode. After I demonstrated, and the balloon flew across the classroom before it fell to the ground, I gave the students some materials to design a rocket. They were given a straw, masking tape, string, and a balloon. Next, they were asked to use the materials to control the direction of the balloon so that it hits one of the three targets located around the classroom. The students began drawing their ideas. The first idea was to put the straw into the balloon. We tested the idea, and found it did not control the direction of the balloon. Next, I ask how we could use the string and the straw together. One student suggested we put the string through the straw. We did, and noticed that the straw moves along the string using force! Finally, the students wondered how we could attach the balloon to move the straw! I was quite a process. They were so excited, and so successful!
