In this activity, learners explore why the sky is blue. Learners model the scattering of light by the atmosphere, which creates the blue sky and red sunset, using a flashlight and clear glue sticks.

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 mix a solution of luminol with hydrogen peroxide to produce a reaction that gives off blue light.

In this outdoor activity, learners discover how the environment around a building affects the growth of plants.

In this activity, learners simulate the energy transfer between the earth and space by using the light from a desk lamp desk lamp with an incandescent bulb and a stack of glass plates.

In this outdoor activity, learners use only their senses to to find the extremes of several environmental variables or physical factors: wind, temperature, light, slope and moisture.

In this activity, learners experience firsthand how marine animals' adaptive coloration camouflages them from prey.

This is an activity about turbidity, or the amount of sediment suspended in water.

In this outdoor, nighttime activity, learners gather around a brightly lit, white surface and study the behavior of nocturnal animals attracted to the light, particularly night fliers.

This simple hands-on activity demonstrates why the sky appears blue on a sunny day and red during sunrise and sunset.
