Teaching Materials
Prerequisites:
- Ensure students are familiar with sources of energy and the difference between clean energy and fossil fuels.
Classroom Implementation:
- Pair this resource with other articles about various forms of clean energy to have students compare the different sources.
- Assign this article as homework for students to read in preparation for a discussion about whether we should implement hydropower or other sources.
- Print the quiz linked at the bottom for students to demonstrate their understanding of the material. Note that the answer key is also available through this link.
Differentiation:
- Support students by providing guided notes where they can record new vocabulary, the benefits and drawbacks of hydroelectricity, and any questions they have.
Related Resources:
- Pair the article with this social studies lesson plan to have students research the drawbacks of dams and consider whether they should be removed.
Sustainable Development Goals Connections:
- Use this resource to make connections to Sustainable Development Goal 7, Affordable and Clean Energy.
This resource investigates hydropower as a source of renewable electricity. The text is exceptionally thorough, supported by a wealth of well-sourced figures. The description of the hydrologic cycle is notable for its clarity. Hydropower is presented as a response to climate change, with emphasis on environmental impacts and uncertainties that may impact hydropower availability. This resource is recommended for teaching.
