Specification:
Features include: 2 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; 1 Non-polar
ethane, so students can see and feel how non-polar molecules interact
with polar molecules; 1 Hydroxyl group, so students can
make ethanol; CD with Lesson Plans (6-cup Water Kit Set only).
These Molecular Designs Magnetic Water Kits will help students to understand the structure and properties of water.
They can "see and touch" water in its 3 dimensions and embedded magnets
enable students to "feel" hydrogen and oxygen atoms attract and repel
each other.
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.
All atoms are magnetised to reflect their positive or negative charges (except non-polar ethane).
The 6-Cup Water Kit also includes a CD with Secondary school lesson plans.
Each Molecular Designs Water Kit cup includes: 12 water molecules, 1 sodium, 1 chloride, 1 ethane and 1 hydroxyl group.
