As part of the activities taking place during Science Week, the children in Y4 and Y6 have been investigating buoyancy. They were challenged to build a boat which could carry as many marbles as possible.
The children were all given the same sized piece of foil to build the boat from and the same paddling pool full of water to float their boats on. This made the test fair. They then counted how many marbles their boats could carry, before they sank…..right down to the very depths of the ocean! It was a fun activity- and the children discovered that the bigger the boats surface area, the more marbles it could carry. Have a look at the clip below to watch the children carry out their fair tests:
