Student groups are given a set of materials: cardboard, insulating materials, aluminum foil and Plexiglas, and challenged to build solar ovens. The ovens must collect and store as much of the sun's energy as possible. Students experiment with heat transfer through conduction by how well the oven is insulated and radiation by how well it absorbs solar radiation. They test the effectiveness of their designs qualitatively by baking something and quantitatively by taking periodic temperature measurements and plotting temperature vs. time graphs. To conclude, students think like engineers and analyze the solar oven's strengths and weaknesses compared to conventional ovens.

Students explore the methods engineers have devised for harnessing sunlight to generate power. First, they investigate heat transfer and heat storage through the construction, testing and use of a solar oven. With a lesson focused on photovoltaic cells, students learn the concepts of energy conversion, conservation of energy, current and voltage. By constructing model solar powered cars, students see these conceptual ideas manifested in modern technology. Furthermore, the solar car project provides opportunities to explore a number of other topics, such as gear ratios and simple mechanics. Both of these design and construction projects are examples of engineering design.

In this activity, learners use the Sun's energy to cook marshmallows. Learners construct the solar oven out of simple everyday materials. They experiment to see how the color of the marshmallow (vanilla or chocolate) and height of the straws affect cooking time. Use this activity to introduce learners to solar energy and reflection. Note: this activity requires adult supervision.

In this lesson, students will first discuss where energy comes from, including sources such as fossil fuels, nuclear, and such renewable technologies as solar. After this initial exploration, students will investigate the three main types of heat transfer: convection, conduction, and radiation. Students will learn how properties describe the ways different materials behave, for instance whether they are insulators or conductors. Students will complete a crossword puzzle to reinforce their vocabulary in this content area. The class will then focus on the acquisition and storage of energy through the design, construction, and testing of a fully functional solar oven.
