In this fun and simple hands-on astronomy activity, learners construct a model of our place in the Milky Way Galaxy and the distribution of stars, with a quarter and some birdseed.

In this quick activity, learners observe how the added sugar in a can of soda affects its density and thus, its ability to float in water.

Use this hands-on activity to demonstrate infrared and thermal radiation.

In this demonstration/experiment, learners discover that different colors and materials (metals, fabrics, paints) radiate different amounts of energy and therefore, cool at different rates.

In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.

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