In this activity, learners discover that one way to cool an object in the presence of a heat source is to increase the distance from it or change the angle at which it is faced.

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 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 two-part activity, learners work in pairs to examine the four basic stages of a turbine engine.

In this activity, learners visualize the differences in water density and relate this to the potential consequences of increased glacial melting.

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

In two separate bags, learners mix water with Epsom salts and detergent.

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.
