We weighed marbles (approx. 1g each), estimated, and then measured; how many marbles it took to sink our paper boats.
Control: We all made the same style paper boats
We found out the following:
- Paper boats don't have a very long life once they touch the water!
- If you put a whole lot of marbles in your boat and cause an edge to take on water it'll VERY quickly sink your boat
- How many marbles depended on how you put them in your boat and also how balanced your boat
