Primary 5

Primary 5 explored the concept of buoyancy by making their own boats out of tin foil! They learned that buoyancy is the force that helps objects float in water. Each group designed a tin foil boat and then tested how many marbles it could hold before sinking. They had so much fun experimenting with different shapes and sizes of boats to see which one could hold the most marbles. Primary 5 discovered that if the boat was bigger and had more layers of tin foil, it could hold more marbles. Some boats could hold up to 205 marbles!
