Why Does Water Dissolve Salt?
Individuals explore solubility by modeling how water dissolves salts. They then view a video and compare how well water and alcohol dissolve salts, relating their comparisons to the structure of each molecule.

Crystal Growing
Students grow crystals and document their observations by recording timeing and growth. Additional characteristics of crystals are observed under a black light, by growing under different conditions and mineral content is determined.

Properties of Salt
Young scholars see how the properties of salt affect the color of flame, the flow of electricity, and the freezing temperature of water. They identify salt and sugar crystals under a microscope and discuss various practical uses of salt.
