Balloon rocket

Week 2: Balloon Rocket experiment
Today Flynn, Solomon, the whole class and I did balloon rocket experiments. We did it in groups of 3 or 2. We could do it from different heights but Solomon and Flynn and I didn't try it from different heights, we stayed at the same height. Sometimes it spiraled but sometimes it didn't.

Week:3 Drag
Today's experiment  was about balloon rockets with a small piece of paper attached.  The the distance was 3.46, that was how long the string was. Then we did another experiment with a bigger piece of paper and the weird thing was that with the bigger piece of paper it stopped in the middle of the rope and then it started again and it went to the end but it went very slow.  I think it acted differently because the paper was a different size.  I think the wind pushed it.
