Science journal 3

Science journal
Rocket balloon
Week 3
In week 3 we did the rocket balloon experiment again but instead of wool string we used fishing wire. I reckon the difference between the two times we did the experiment was that with the fishing wire the balloon went across a lot smoother. I predict that the fishing wire is smoother because it has less friction. I wonder if you did the experiment on a piece of ribbon, if it would go faster? I saw that the balloon spun as it when across the string, I think this is because of the wind.
On the rubric I am sitting at multistructural because I have many ideas about the rocket balloon and how to improve but I don't know how to teach others.
