The Molecular Model Set For Water

Water's various chemical and physical properties are determined by the three dimensional shape of the water molecule. 

Students explore the attractions between water molecules that are responsible for creating surface tension. Electrical

forces between the water molecules are simulated with six magnets. The white hydrogen atom of one water molecule

is attracted to the red oxygen atoms on the other water molecule. Color and size of foam fish may vary.

The Structure of Water Kit contents:
2 magnetic water molecules
1 foam fish
1 Student Activity Guide
