Magnetic Water Molecule Kits, Set 6
These 3D Molecular Designs Magnetic Water Kits© will help students to understand the structure and properties of water. They can ""see and touch"" water in its dimensions and embedded magnets enable students to ""feel"" hydrogen and oxygen atoms attract and repel each other. Features include: Magnets in oxygen atom, so students can make ice; Permanently embedded magnets (magnets won't fall out when atoms are unassembled); Removable hydrogen atoms, so students can assemble water and compare hydrogen bonds to covalent bonds; Non-polar ethane, so students can see and feel how non-polar molecules interact with polar molecules; Hydroxyl group, so students can make ethanol; CD with Lesson Plans. As students explore the 3D water kit they will be able to: See spontaneous bonding, Compare hydrogen bonds to covalent bonds, Make ice crystals, Dissolve salt, Evaporate water, Add non-polar ethane to water, Create ethanol, Explore capillary action. Each 3D Molecular Designs Water Kit© cup includes: 12 water molecules, sodium, chloride, ethane and hydroxyl group. All atoms are magnetised to reflect their positive or negative charges (except non-polar ethane). This 6-Cup Water Kit© also includes CD with Secondary school lesson plans.
