Cooking with the Sun: Creating a Solar Oven

For this activity, students will be given a set of materials: cardboard, a set of insulating materials (i.e. foam, newspaper, etc.), aluminum foil, and plexiglass. Students will then become engineers in building a solar oven from the given materials, keeping in mind that the oven should not only be able to collect as much of the sun's energy as possible but also to store it. Students will experiment with heat transfer through conduction by how well the oven is insulated and radiation by how well it absorbs solar radiation. Upon completion they will test the effectiveness of their designs both qualitatively and quantitatively. Qualitatively, they will attempt to actually bake something in the ovens. Quantitatively, they will take periodic temperature measurements and plot a temperature versus time graph. Afterwards, students will think like engineers and discuss the solar oven's strengths and weaknesses when compared to a conventional oven. (less)

Exploring Solar Power

This unit provides students the opportunity to explore methods engineers have devised ... (more)

This unit provides students the opportunity to explore methods engineers have devised for harnessing sunlight to generate power. Students will initially explore heat transfer and heat storage through the construction, testing, and eventual use of a solar oven. With a lesson focused on photovoltaic cells, students will learn the concepts of energy conversion, conservation of energy, current, and voltage. Through construction of model solar powered cars, students can 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. (less)

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. (less)
