Rocket Launch

Sirus seventh and eigth graders recently made and launched homemade bottle rockets. We were put into groups of three or four people, we had a few class times to plan and make our rockets. The rockets were made out of 1 and 2 liter plastic bottles, constrution paper and mylar. The design and overall structure was up to the group to decide. Next we went and launched our rockets. We launched them with 1/2 full of water, 1/4 full, 3/4, and all the way full. We collected the data to see which made the rockets go further. We figured out that having the water filled up half way made the rockets go the furthest. what a great time.
