Synopsis
- This lesson explores hydropower as a renewable energy source.
- Students build and test a model water wheel as an engineering challenge, consider the drawbacks and benefits of hydropower, and design a labelled poster of a hydropower station that includes a related STEM career over the roughly 60-minute lesson.
- Though this lesson was made for students in Australia, teachers worldwide can implement this lesson by substituting their own national data.
Teaching Materials
Preparation:
- A free cool.org account is required to access the full lesson and its companion materials.
Prerequisites:
- Ensure students are familiar with renewable energy concepts and the term kinetic energy.
- Though this is the third lesson in the unit, students do not necessarily need to have completed the preceding lessons.
- Consider introducing students to different kinds of circuits before teaching this lesson.
Materials:
- A small ball of plasticine or modeling clay
- 6 icy-pole (popsicle) sticks
- 1 skewer
- Thin card
- Sticky tape
- Scissors
Extensions:
- Have students investigate a local or regional hydropower facility and identify one environmental benefit and one environmental challenge of hydropower.
Sustainable Development Goals Connections:
- Connect this resource to SDG 7, Affordable and Clean Energy, and SDG 13, Climate Action.
Scientist's Note:
- This resource counters one-sided claims about hydropower by featuring a balanced analysis of the benefits and potential environmental impacts of hydropower generation.
