Learning Goal(s):
Explore causes and effects of climate change as related to energy production. Develop a working understanding of varying stakeholder perspectives on the causes and effects of climate change. Through hands-on exploration, build a working speaker that can connect to a cellphone. Use DIY speakers as a model to observe the process of producing electrical currents with a simple generator. Design, build and refine a wind turbine to efficiently convert mechanical energy into electrical energy. Design, build and refine a system that is the most effective at converting the sunlight into electrical energy. Students develop models to study the relationship between the Earth’s atmospheric composition and the Earth’s surface temperatures using simple diagrams. Students reflect on the impact of energy sources and power production on the environment. Students utilize their knowledge of how energy generation processes impacts the environment to inform how and why they develop a 50-year Energy Plan for their local community.
