Super Scientist Christina taught us about density by filling 2 clear jars with water. She then put an orange with a peel in one jar, and it floated to the top. She put a peeled orange in the other jar of water, and it sank. She taught us that the peeling causes little pockets of air to surround the orange causing it to float like a floatie in a pool. The orange with no peeling did not have the air pockets to keep it afloat. This was really neat, Christina. Great job!
