Unit 7 focuses on teaching students about the social and environmental impacts of clean energy sources by having them develop an understanding of electricity concepts and applications. Students will learn about different methods of power production and how they affect individuals, the environment, and society. This will allow students to make informed judgments about the advantages and disadvantages of alternative and renewable energy sources. Unit 8 has students investigate, design, plan, and build an electrical generator powered by a renewable energy solution from Unit 7 that is creative and can charge a mobile phone battery.
