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.

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

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

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.

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.
