Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

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

This activity shows how our experience of the Sun changes with time and location. The sun dagger at Chaco Canyon is thought by many to be a sort of ancient timekeeping device.

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.

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.

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

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

In this activity, learners discover that one way to cool an object in the presence of a heat source is to increase the distance from it or change the angle at which it is faced.
