In this activity, learners examine fingerprints. Learners leave a hidden print on a surface and then make their own print detecting powder from graphite (found in pencils).

Using electrolysis, learners produce hydrogen gas and oxygen gas from water molecules in a solution.

Learners explore how recyclers take advantage of the different properties of materials, such as magnetism and density, to separate them from a mixture.

In this activity, learners electrically plate zinc onto brass objects.
