The Hot and Cold lessons use everyday materials, but gathering thirty of everything takes an evening. This kit arrives counted out by lesson, with spares, so you can open the box and teach.

The reusable parts (tubs, thermometers, jars) last for years. Each year, a refill pack replaces what gets used up.
