The last day we do an experiment we called, orange experiment.
It consists to put an orange into water and see if it floats.
First we put the orange into the water, we see that it floats, because of the skin of the orange, the skin of the orange have little bubbles that keep the air into.
Then we cut the skin of the orange, and we put it into the water. We can see that it sinks because it don’t have air.
