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

In this laboratory experiment, learners explore how effectively different sunscreens protect yeast cells from damage caused by ultraviolet (UV) radiation.

Learners experiment with a commercial photo-sensitive paper (Sunprint® or NaturePrint® paper). They place opaque and clear objects on the paper and expose it to bright light, observing the results.

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.

This is an activity to do when there is a solar eclipse!

In this activity, learners use tonic water to detect ultraviolet (UV) light from the Sun and explore the concept of fluorescence.

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 outdoor, beach activity, learners use tennis balls, water balloons and other simple devices to investigate the movement of waves and currents off a sandy beach.

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

This fun, nighttime hands-on astronomy activity lets learners explore how long it takes for light from different objects in the universe to reach Earth.

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.

This fun hands-on astronomy activity uses a variety of simple props to help learners understand why they see what they see in a telescope.

This is a classic exercise for visualizing the scale of the Solar System.

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

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.
