In this activity, learners verify that the Sun appears in a different location at a specific time every day of the year with one exception: on the Equinoxes.

In this experiment, learners work in teams to investigate how the color of a surface influences its ability to reflect light and therefore heat.

In this activity, learners explore how the power of the sun can be harnessed to heat and cool a building.

In this experiment, learners construct an equilateral triangle using graph paper, a pencil, protractor and ruler. They also make a "laser triangle" using a laser pointer and front-silvered mirrors.

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 activity, learners experiment with shadows and light sources to understand the relationship between the angle illumination and the shadow's length.

In this activity, learners will make their own prism and use a glass of water to separate sunlight into different colors.

“Exploring Earth: Investigating Clouds” is a hands-on activity in which visitors create a cloud in a bottle and explore it with laser light.

This activity guide features three related explorations to help learners ages 3-6 investigate shadows via the following science concepts: A shadow is made when an object blocks the light; you can chan

Can gelatin (like Jell-O ®) change the speed of light?

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 activity (posted on March 12, 2011), learners follow the steps to construct a spectroscope, a tool used to analyze light and color.

In this activity related to climate change, learners examine albedo and the ice albedo feedback effect as it relates to snow, ice, and the likely results of reduced snow and ice cover on global temper

In this activity, learners will measure the length of a shadow and use the distance from the equator to calculate the circumference of the earth.

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

This activity (on page 2 of the PDF under SciGirls Activity: Doghouse Design) is a full inquiry investigation into absorption and reflection of radiant energy.

In this activity, learners make an equatorial sundial, which is simple to construct and teaches fundamental astronomical concepts. Learners use the provided template and a straw to build the sundial.

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.

In this activity, learners test the Law of Reflection based on experimental evidence. Learners produce raw data and explanations based on their data: pencil tracings of incident and reflection rays.
