Science Experiment: Sink or Float with Oranges

This is a really fun experiment for children in order to learn about floating and sinking. This is an easy, hands-on experiment.

All you need is a couple of oranges( a peeled orange and an unpeeled one) and a water tank. Ask the children to predict which one will float and which one will sink. They’ll learn about density – that the unpelled orange floats as its rind has tiny pockets of air.

If cut in half and removed the pulp, the unpeeled orange can be turned into a nice floating little boat. For more fun, blow into a straw to create waves.
