Floating orange Experiment

Yesterday we conducted an experiment using oranges.

We asked the question "Will an orange float in water?" "Will a peeled orange float?"
First we predicted what we thought would happen.

We were amazed that the peeled orange sank to the bottom and the unpeeled oranges floated!!! It was because the orange that still had it's skin has air pockets in it's skin and therefore floats! Wow!
