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 quick optics activity, learners use a dim point of light (a disassembled Mini MagLite and dowel set-up) to cast a shadow of the blood supply in their retina onto the retina itself.

In this activity, learners explore light and shadows by creating a lantern they can keep on their nightstand.

In this activity, learners will create their own simple shadow puppets, and experiment with light and shadow while playing with them.

Learners construct one or more of the following kinds of sundials: a shadow plot, a horizontal sundial, and a diptych sundial.

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

In this activity, learners use a simple 3D model to discover why the Moon has phases.

In this activity, learners will see how UV light affects colors over time by making their own sunprint on construction paper.

In this optics activity, learners discover that not all shadows are black. Learners explore human color perception by using colored lights to make additive color mixtures.

In this activity you'll see how the sun's tilt on its axis changes the length of shadows. For example, why is your shadow longer in winter than in summer?

In this sunny day, outdoor activity, learners observe changes in shadows over time. The activity also helps to develop a sense of the Earth's motion.

If you have lights, cardboard, scissors, and some brass fasteners, you can make shadow puppets! Create a story-telling and design challenge for your learners with this simple and creative activity.

In this three part activity, learners explore and experiment with shadows to learn about the Sun's relative motion in the sky.

“Exploring Earth: Bear’s Shadow” is a hands-on activity designed primarily for young visitors and their families. Participants move a flashlight around an object to make and experiment with shadows.

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.

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.

Exploring the Solar System: Solar Eclipse” is a hands-on activity demonstrating how the particular alignment of the Sun, Earth, and Moon can cause an eclipse.

In this activity, learners explore color, light and shadow by creating their own puppets to hold in front of a light source.
