Float or sink?

3rd Apr 2019

Today we continued with our ‘Unsinkable’ topic by exploring items which float and sink! First, we predicted whether the item would float or sink. Then, we tested the items in water. We were surprised by some of our findings. We found out an orange with the peel on will float, but when the peel is removed the orange will sink... Why do you think this is?
