First we explored this...
Next up was Balloon Rockets!
| First we had to blow up a balloon and secure it with a rubber band. |
| Then we taped a straw on top of the balloon and put a string through the straw. |
| We wanted to investigate what would happen when we let the air out of the balloon. |
| It moved! |
Some of our balloon rockets worked better than others, but that gave us a great lesson as scientists. We had to think about changes we would make to our design just like real scientists have to do all the time.
