Floating Orange Experiment

- Vase – Water – 2 oranges or clementines

Materials Needed:

Fill the vase 3/4 full of water and drop an orange with the peel on into the water. Predict if it will float or sink.

Step 1

Next remove the orange and drop in a peeled orange.  Predict if it will float or sink.

Step 2

Finally add the unpeeled orange.  Think about why one floats and one sinks.

Step 3

Air trapped inside the porous skin of the orange causes it to float while the peeled orange sinks.
