A FUN tool to help you teach water concepts. Your students will use these magnetic water molecules to discover hydrogen bonding, make ice, dissolve salt, evaporate water, explore transpiration, create ethanol, and much more.
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 can feel the various strengths of hydrogen, covalent and ionic bonds. They can explore the water cycle – even make ice. They also can show the differences between molecular adhesion, cohesion and capillary action and demonstrate surface tension, evaporation, condensation and solubility.
Each single Water Kit© cup includes pieces for 12 water molecules, 1 sodium, 1 chloride, 1 ethane and 1 hydroxyl group. The embedded magnets in atoms in this molecular modeling kit reflect the correct positive or negative charges (except for non-polar ethane) to let students experience molecular attraction or repulsion hands-on.
*North and south poles on embedded magnets simulate the partially positive and negative charges of oxygen and hydrogen atoms, and chloride and sodium ions.
**The hydrogen pieces for the ethane model do not include embedded magnets, since ethane is nonpolar.
