Clean Water Power: Wind, Waves, and Moving Water

I shaped PVC frames with a pipe coming up at each of the four corners and a pipe coming up twice as long in the center of the center beam. A KidWind firefly is on top. There are 7-8 of these structures.
Phenomena: Water Generates Electricity

How can the power of moving water be used to generate electricity? Water is powerful. This is reflected in a series of connected phenomenon videos.

Lesson 1: Moving Water Into Moving Electrons

Students explore the power of water phenomena through videos of moving water then create a driving question board around how the power of moving water can be used to generate electricity. Students are introduced to the concept of hydroelectric power through content exploration and discussion.

Lesson 2: Electromagnetic Induction

This lesson builds on students’ prior knowledge about how electricity works. Students build a simple motor and test the voltage produced.

Lesson 3: What Does It Take to Make A Functioning Circuit?

This lesson takes students through different hands-on and virtual circuit-building activities in order to make sense of the essential question: What does it take to make a functioning circuit?

Lesson 4: Where is the Clean Water Power Around Me?

This lesson has students use hydropower, wave power, and wind power mapping tools to map the renewable resources around them on a large classroom map of their region, state, or North America.

Lesson 5: Social, Emotional, and Equity Discussions in Clean Water Power

This lesson has students jigsaw a bank of readings on the social, environmental, and equity issues with clean water power in order to make sense of how water power impacts the environment and people. Additionally, students will explore energy sovereignty and tribal energy independence in the Pacific Northwest to learn about how hydropower has impacted tribal nations.

Lesson 6: How Do Variables Affect Power Generation in a Hydroelectric Dam?

This lesson has students make a claim on which configuration will generate the most power in an in-class water power demonstration: Height of water in a bucket (reserve), Length of Penstock, or Height difference between penstock and inline generator. Students then test the variables and collect data. Finally, students compare results with classmates’ and develop a claim, evidence, and reasoning paragraph to support or refute their claim.

Lesson 7: Exploring Different Forms of Water Power

Students will build a model of a Marine Wave Generator (Kidwind Offshore Floating Wind Buoy, NEED’s Model Wav Generator Buoy, or Air Buoy) and test it to collect data and observe how water power is converted into electricity.

Lesson 8: Careers in Renewable Energy

Students create a trading card about a career in renewable energy that interests them. Students can also explore different careers in Hydropower through a “Hydropower Careers Guess Who” game.

8 Lessons / 10 periods of 45-60 mins

This unit strives to answer the question: “How can the power of moving help communities by generating electricity?” Through a variety of lessons centered on the phenomena of the power of moving water, students will develop skills in circuits, model building, and testing. Students will explore issues surrounding clean water, energy, and careers.
