The Great Volume Exchanger...or The Magic Matter Maker
This lesson uses a discrepant event to pique curiosity and provide an excellent metaphor for a problem in science that can be addressed in a scientific way. Water is poured into a magic box, and out comes a much larger volume of water (or other liquid). Students will learn that science is uncertain because scientists can make more than one workable model to explain their observations.
