In this activity about electricity and magnetism, learners discover how a doorbell works. A coil of wire with current flowing through it forms an electromagnet that acts similar to a bar magnet.

Cardboard Automata are a playful way to explore simple machine elements while creating a mechanical sculpture.

In this activity about chemistry and electricity, learners form a battery by placing their hands onto plates of different metals.

In this STEAM activity, learners create a "pixel tube" to explore reflections of light and color mixing.

In this activity, learners use pegboard and straws to build a three-dimensional model of the periodic table.

In this activity best suited as a demonstration, learners observe that when a piece of iron gets too hot, it loses its ability to be magnetized.

In this optics activity, learners discover that not all shadows are black. Learners explore human color perception by using colored lights to make additive color mixtures.

In this activity, learners construct a simple electrolysis device. With this device, learners can decompose water into its elemental components: hydrogen and oxygen gas.

In this activity, learners use crayons to draw conclusions about rocks and the rock cycle.

In this activity, learners build scaled-down structures and cantilevers in a series of "building out" challenges with bamboo skewers and tape.
