Climate change demands that the world must transition away from fossil fuels to renewable energy sources. This short, animated video teaches students about wind power by explaining how air movement transforms into mechanical energy using turbines. The film also describes how the efficiency of wind power depends on optimal locations which sometimes conflict with human land use and disrupt bird migration. As they use an included worksheet to guide their discussions, pupils will understand how wind technolgy is evolving to minimize impacts while utilizing an abundant natural resource to produce electricity without carbon emissions.
This video supports Grade 3-6 Science curriculum related to renewable resources and electricity. The film builds understanding of air movement and kinetic forces by illustrating how turbines work to harness and transform wind energy. Students will also become aware of the importance of clean energy technologies in reducing future global temperature increases.
To extend the learning experience a class could build and test several PVC windmill demonstration models. Their designs might be displayed at a community event that includes public information about alternative energy sources and tips for reducing home energy consumption. The US Department of Energy has a free set of detailed instructions for designing, constructing and testing a simple windmill at this link.
