Students work in groups to conduct an investigation about objects that float and sink.
They each have 3 different size balls and a tub of water. They have to push the balls under water, then draw labelled diagrams to show what happened.
At the end of the lesson the teacher will relate this lesson to forces: pushes and pulls, helping students understand what happened.
