Middle and high school students working in small groups first use the unassembled pieces of the water molecules to investigate properties of, and interactions between, the model parts before assembling water molecules. Among the questions to explore:
What could these plastic pieces represent? What could the interactions represent? What does a water molecule look like? How do water molecules interact? What properties of water result from these attractions? How could these magnetic molecular models be used to show water as a gas, liquid, and solid? Additional student challenges include modeling the 3-D geometry of ice crystals and using surfectants to make an object stay on top of a water surface.
