DESIGN A ROCKET
We investigated how rockets launch. Working in groups, we did a rocket launch. First we blew up a balloon and let it go. We watched it fly around the room. Then we decided to control the path of the balloon by connecting it to a piece of string. We tied the string to two chairs. We blew up a balloon and kept it closed using a clothes peg. We attached it to the side of the string using sellotape. Then we removed the peg and the balloon flew along the string like a rocket. The air coming out the back of the balloon pushed the balloon forward like a rocket. We investigated a rocket launch using two balloons.
