In this activity, learners will explore the ways natural materials can produce sounds. Appropriate for any age, learners can make individual music or create a symphony with others.

In this activity (page 1 of the PDF under SciGirls Activity: Double Dutch), learners will stand twelve feet apart swinging a rope at the slowest tempo possible while someone uses a stopwatch to record

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 fun and simple hands-on astronomy activity demonstrates the shadow of the Earth as it rises as a dark blue shadow above the eastern horizon.

Use this Moon Map Guide to help learners identify features on the Moon, while looking through a telescope.

In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.

In this optics activity, learners split white light into all its component colors using three household items: a compact disc, dishwashing liquid, and a hose (outside).

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.

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

This fun astronomy activity allows learners to experience finding stars in the night sky that will eventually go supernova. This activity is perfect for a star party outdoors.

An ordinary camera has a lens that makes an image on film. In a pinhole camera, a small hole replaces the lens.

In this activity, learners model the flow of energy from the sun as it enters a photovoltaic cell, moves along a wire and powers a load.

In this activity, learners explore how polarizing sunglasses can help diminish road glare.

In this optics activity, learners use a shoebox, colored cellophane and sunlight to "change" the colors of gumballs. Learners will be surprised when the green and blue gumballs appear black!

In this activity on page 13 of the PDF, use a special plastic card that has been painted with a chemical that changes color when it is in UV light.

In this activity, learners make their own Sun tracker to explore how ancient civilizations around the world studied the Sun.

In this outdoor activity, learners explore UV rays from the Sun and ways to protect against these potentially harmful rays.

In this activity, learners use binoculars (or a telescope) to identify and track sunspots. If using binoculars, learners need a pair that can be secured on a tripod.

In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.
