In this activity, learners discuss and investigate how cameras, telescopes, and their own eyes use light in similar ways.

In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.

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

This hands-on astronomy activity allows you to create a “cutaway” telescope to clearly show how reflector and refractor telescopes work.

Learners follow directions to construct a solar oven that really cooks! The solar oven uses aluminum foil to reflect sunlight into a cooking chamber, which is painted black.

Learners observe different light sources, outdoors and indoors, using prism glasses (diffraction glasses) and color filters.

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

In this activity, learners use the Sun's energy to cook marshmallows. Learners construct the solar oven out of simple everyday materials.
