In this activity, learners explore color, light and shadow by creating their own puppets to hold in front of a light source.

In this activity, learners investigate the properties of graphene and graphite.

In this physics activity (page 6 of the PDF), learners will demonstrate air has weight by comparing an inflated balloon to a deflated one.

In this demonstration, adult learners create a lava lamp using beer and nuts! Use this pub-themed activity to demonstrate the effects of buoyancy and bubbles.

In this activity, learners explore a scale by comparing objects, which look similar but have different weights. Learners predict and then measure the weights of various objects using a scale.

Learners experiment with a commercially available liquid-crystal coaster. They warm the material with their hands for varying lengths of time and observe the changing colors that result.

This is an activity exploring color and color mixing.

Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.

In this activity, learners observe color mixing and absorbency using colored tissue paper and spray bottles.

In this activity, learners investigate the effect of heat on a reaction.

This is a highly visual demonstration that illustrates both the effects of density and chemical reactions.
