ZOOM! Have you ever built a balloon rocket? Well, I am here to tell you how to build one. On Monday me and my group were making a balloon rocket. We used string, straw, tape, and a balloon.
First, we put the straw, tape and the balloon together by threading the straw onto the string. We taped the balloon onto the straw. We tested how high the balloon would go. We blew up the balloons into different sizes, small, big and medium.
Next we tested out how far the balloons went. The big balloon went all the way to the end of the string. The small balloon didn’t go far and the medium one went halfway. It was so fun doing this experiment.
We also did a height experiment with the balloon rocket. We did it on the chair. Some of my group was on the ground and Ula was on the chair holding the string. We tested how far it will go when the string is held up high. It was so fun to do the experiment. My group is the best.
Lastly, we went outside to the teachers who were doing the same experiment. It was so fun. They had to hold the string and they tied the string to the pole. The balloon went all the way because the wind was pushing it too. The experiment was so fun and the teachers were the best.
