While learning about density and bouyancy this week in Science, the students started a discussion about oranges. One student proposed that an unpeeled orange would sink, and a peeled orange would float. To test this theory, Ally and Sofia carried out an experiment for 5B. As a result of the experiment, the fifth graders learned that an unpeeled orange really does sink, while a peeled orange floats. Can you guess why? Ask your child for the explanation!
