Floating and Sinking

This week we experiment with different objects to see which float or sink. Fill a basin with water and try out some objects at home. Record your results. See the worksheet below. Experiment with an orange. Does it float or sink? Peel the orange, now try it again! Is the result any different? Why does an orange with peel float? Compare it to a child's rubber ring. The peel is full of tiny pockets of air which help it float.
