How Can Freezing Make Something Warmer?
Crazy fact—freezing liquid actually gives off heat! Young scholars investigate the transfer of energy when liquids freeze using a chemical heat pack. The heat pack gives off heat as its liquid core freezes.

Solubility
Fifth graders determine the difference between a soluble and an insoluble solution and how to increase solubility. They make a saturated solution using solvents at different temperatures.

Crystals
Students investigate crystal formation, their shapes and the best places to cleave crystals for smooth edges. In this crystal lesson plan, students experiment to form crystals with Salol as well as with copper wire and Silver Nitrate....
