Senior 1 Physics Assignment: Density, Floating and Sinking

This two-page assignment from Trinity College Nabbingo presents four questions for Senior 1 physics learners. It uses a mango and a passion fruit to explore why objects with equal volumes can have different masses. Learners describe how to determine water density using a soda bottle and a beam balance, then attempt a density calculation. A practical activity compares the behaviour of intact and crushed drink cans in water. The final question asks learners to explain why an empty aluminium saucepan floats while a small solid aluminium bar sinks.
