This quick demonstration (on page 11 of PDF) allows learners to understand why scientists think water ice could remain frozen in always-dark craters at the poles of the Moon.

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.

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.

In this activity, learners investigate passive solar building design with a focus solely on heating.

Many people think the different stages in the life of a star are actually different types of stars, rather than just stages in the life of a single star.

In this activity, learners use candy pieces and a cookie to make an accurate model of the Sun they can eat. Parts of the delicious model include solar granules, sunspots, and solar prominences.
