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

In this math-based activity, learners model the intensity of light at various distances from a light source, and understand how astronomers measure the amount of sunlight that hits our planet and othe

In this space science activity, learners explore transits and the conditions when a transit may be seen.

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

In this activity, learners carry out a scientific investigation of dust in their classroom. Learners produce an analysis on graph paper of the dust they collect over the course of a few days.

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.
