Your students will feel bonds with these magnetic water molecules. Embedded magnets accurately reflect positive and negative charges, allowing your students to:

  • Understand polarity
  • Create non-polar ethanol
  • Compare the various strengths of hydrogen, covalent, and ionic bonds
  • Investigate capillary action and transpiration
  • Demonstrate the differences between adhesion and cohesion
  • Explain surface tension, evaporation, and condensation
  • Show the states of water (gas, liquid, and solid)
  • Dissolve salt to explore solubility
  • Model ice structures and snowflakes
  • Define and create models of the states of osmosis
  • Understand the basics of water autoionization, dissociation and pH

Water Kit© Basic Lessons

Numerous lessons and activities are possible with 3D Molecular Design’s Water Kit©. First, you and your students will use the magnetic water molecules to explore the concepts of polarity and hydrogen bonding.

Water Kit© Osmosis Lesson

Living things must perform vital activities in order to maintain their existence, including moving water in and out of cells. It is important for your students to understand how water flows in and out of a cell through the membrane that surrounds cells, as it directly impact a cell’s ability to survive. The passive transport of water across a selectively permeable membrane is called osmosis.

Water Kit© pH Lesson

Your students will use the Water Kit© to create a physical representation of the autoionization of water, describe and produce a physical representation of the dissociation of a strong acid and a strong base, and associate a high hydronium ion concentration with low pH and a high hydroxide ion concentration with a high pH.

Water Kit© Patterns In Crystal Structures

This activity, intended for grades 4-5, uses the magnetic water models and a guided-inquiry approach. It 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.

Water Kit© Constructivist Lab

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.

Water Kit© Ice and Snowflakes

Scientists have described 14 structures of ice, many of which can be constructed with one or more Water Kit© sets. 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 Water Kit© sets.
