Many lessons and activities are possible with our Magnetic Water Molecule Kit The best place to start is with this 29-page Basic Lesson. First, you and your students will use the magnetic molecules to explore the concepts of polarity and hydrogen bonding. You can then use this kit to teach adhesion, cohesion, and capillary action; surface tension; states of water; evaporation and condensation; and solubility. Finally, your class can have fun with water with our "Just for Fun" snowflake creation activities.
This 29-page Basic Lesson includes teacher notes and student handouts.

Your students can explore osmosis by using the Magnetic Water Molecule Kit to make models of the hypertonic, hypotonic, and isotonic states of osmosis and predicting the flow of water in each state. They also will recognize the necessity of aquaporins in water transport across a membrane.
This 10-page Osmosis Lesson includes teacher notes and student handouts.

This activity, intended for grades 4-5, uses the Magnetic Water Molecule Kit and a guided-inquiry approach. t will help your students observe patterns and forms. Your students begin by identifying the number of hexagons in ice. Then they construct and compare cubic and hexagonal ice structures before creating a snowflake.

With this 2-page Constructivist Lab, middle and high school students working in small groups will 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.

Scientists have described 14 structures of ice, many of which can be constructed with one or more Magnetic Water Molecule Kits. Here are lessons for building cubic ice (Ice 1c), which is present in the upper atmosphere and requires 10 water molecules; hexagonal ice (Ice 1h), which falls as snowflakes and is formed with 12 water molecules; and more elaborate snowflakes, which can be created with additional Magnetic Water Molecule Kits.
