In this video, host Matt Ferrell describes how underwater turbines can use tidal power to generate clean electricity.
Students will learn about the pros and cons of several types of tidal turbines that are being developed and used around the world.
Teaching Tips
Positives
This resource is a great way to introduce students to a type of renewable energy technology they may have never heard about.
The video description includes a link to a full transcript and sources.
Additional Prerequisites

This video has a sponsored ad that runs from 3:36 to 4:46.
Students should be familiar with renewable energy and nonrenewable energy.
Differentiation
Science classes could use this video as part of a research project about types of renewable energy, or to inform an engineering design challenge.
Biology classes could discuss which tidal energy solutions pose the highest and lowest risk for ecosystem disruption.

Scientist Notes
This video underscores the role of tidal energy in limiting CO2 levels in the energy sector. It describes various technologies designed to harness tidal energy from tidal waves and oceans. It also explains that some of the technologies, like the barrage, hurt marine resources. The video contains the latest research on tidal power sources. This is insightful and thus, recommended for teaching.
Standards
Science and Engineering
ETS1: Engineering Design
MS-ETS1-1 Define the criteria and constraints of a design problem with sufficient precision to ensure a successful solution, taking into account relevant scientific principles and potential impacts on people and the natural environment that may limit possible solutions.
HS-ETS1-3 Evaluate a solution to a complex real-world problem based on prioritized criteria and trade-offs that account for a range of constraints, including cost, safety, reliability, and aesthetics, as well as possible social, cultural, and environmental impacts.
PS3: Energy
HS-PS3-3 Design, build, and refine a device that works within given constraints to convert one form of energy into another form of energy.
