3D Molecular Designs Water Kit is designed to teach water concepts. Students can use these magnetic water molecules to discover hydrogen bonding, explore transpiration, create ethanol, explore capillary action, compare hydrogen bonds to covalent bonds, and more. Each single Water Kit cup includes 12 water molecules, 1 sodium, 1 chloride, 1 ethane, and 1 hydroxyl group. All atoms are magnetized to reflect their positive or negative charges (except non-polar ethane) to let students experience molecular attraction or repulsion. Go to www.3dmoleculardesigns.com for middle school and high school lesson plans. Designed for students to work in groups of 2-4. Purchased with Title IIA Funds administered by the Board of Regents, State of Iowa and donated by Clarke College, Dubuque, Iowa. Two-week loan period. IL 4-12. | |
