In this activity, learners heat ice and water of the same temperature to get a hands-on look at phase changes. This is an easy and inexpensive way to introduce states of matter and thermodynamics.

This is an activity about friction as well as kinetic and potential energy.

This kinesthetic science demonstration introduces learners to four states of matter: solid, liquid, gas, and plasma.

In this activity, learners follow simple directions to explore and create platonic solids.

In this activity, learners use heat to separate zinc and copper in a penny. This experiment demonstrates physical properties and how physical change (phase change) can be used to separate matter.

In this introductory activity, learners discover that sugar and food coloring dissolve in water but neither dissolves in oil.
