We started our science lessons this week by investigating why boats float. We tried different containers to see if the shape matters and then we added gems to the containers to investigate which ones would sink. We found the rounder, wider containers were the best at floating. Two of our containers were filled with 109 gems and they didn’t sink! We learnt that displacement, when the boat pushes the water away, and being hollow helps boats to float even when they are heavy! Have a look at our photos of us investigating!
