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.

Learners model the Sun-Earth-Moon system to show what causes the Moon's appearance to change when viewed from the Earth.

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.

Learners mix a solution containing luminol and copper with a fake blood solution. A chemical reaction between the luminol solution and fake blood (hydrogen peroxide) show learners a blue glow.

In this activity, learners discover that nanoparticles of gold can appear red, orange or even blue. They learn that a material can act differently when it’s nanometer-sized.

In this activity about the solar system, learners use various light sources to examine ice with different components to understand how NASA studies planets and moons from space.
