In a column devoted to interactive resoures for the K-5 classroom, this article features Recycle City, an EPA-produced, student-friendly web site designed to teach students about actions that create a sustainable community. Students will learn about recycling, reducing waste, and using less energy. The column regularly appears in the free, online magazine Beyond Weather and the Water Cycle, which focuses on the essential principles of climate literacy.
Background: students are familiar with static electricity, charge, and sparks. They also know about conservation of energy, forms of energy including potential energy, power, and work. Students will complete a variety of activities using breadboards, which will display various types of circuits and their effect on the flow of electricity.
In this activity, students act as engineers to determine which type of insulation would conserve the most energy.
