In this chemistry challenge, learners discover that many chemical reactions involve heat loss or gain.

In this activity, learners make a solar oven. Learners witness the awesome power of the sun to make a yummy treat--a chocolate chip cookie!

This activity (on page 2 of the PDF under SciGirls Activity: Doghouse Design) is a full inquiry investigation into absorption and reflection of radiant energy.

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 demonstration, cook a cake using the heat produced when the cake batter conducts an electric current.
