Today we continued our buoyancy topic with another experiment. Our challenge was to design a tin foil boat which could hold as much mass as possible without sinking. We were given 1 metre of aluminium foil and used our knowledge of buoyancy to create our boats.
Then it was time to put our boats to the test. We put them into a container of water and added as many marbles as possible until they sank to the bottom.
Our winning boat managed to hold 164 marbles! We discovered that the larger the surface area, the more mass the boats could hold. This means that the buoyant force will help it to float. 🛳
