Description Contents Teacher Resources

A FUN tool to help you teach water concepts. Teachers who use our Water Kits© say they can move through water lessons faster, their students ask more questions, and they are able to discuss concepts in greater depth.

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

Each single Water Kit© cup includes pieces for 12 water molecules, 1 sodium, 1 chloride, 1 ethane and 1 hydroxyl group.

5 of 5 Excellent model for chemistry and biology October 14, 2021
Reviewer: Scott Mellon from Danvers, MA United States  
Our chemistry, biology, and biotech classes all use these models to good effect.  Molecular polarity and intermolecular interactions can be challenging concepts for students, so these kits are a great boon to instructors.  Internal magnets in the atoms mimic hydrogen bonding in getting the models of water molecules to stick together.  The very different strength of hydrogen bonding vis-a-vis the covalent bonds within a molecule are then obvious, making the process of phase changes without disruption of molecular structure clear.  Inclusion of a nonpolar ethane molecule (lacking magnets) that cannot interact with a water molecule reinforces the importance of molecular polarity.  Likewise, inclusion of sodium and chloride ions (also with internal magnets) that can interact with water molecules illustrate solvation of these ions very well.

5 of 5 Love the Water Kit! August 16, 2017
Reviewer: Michelle Barnet from Bandera, TX United States  
I got one of these years ago at CAST, and loved it.  Later purchased the class set, along with the NaCl Lattice Model.  A wonderful teaching aid for biology or chemistry.  They last for years.
