Dunking the Planets

Download This Lesson

Short Description: In this 30-minute demonstration, children ages 9-13 compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods. The children dunk the "planets" in water to highlight the fact that even a large, massive planet -- such as Saturn -- can have low density. They discuss how a planet's density is related to whether it is mainly made up of rock or gas.
