How can we harness the power of the sea to create renewable energy?
Foreword
This lesson will provide the students an opportunity to create a functioning hydroelectric power generator by harnessing wave power. They will get to understand Faraday's Law of electromagnetism and see it in action through the model.
Previous Learning
Visit from hydroelectricity/renewable energy companies for a talk or a workshop (Morlais, Gwynt y Mor, EDF in Dinowrig).
Pupils will have had an opportunity to build working circuits so that they understand the components and how they work.
A visit by Gwynt y Mor renewable energy.
Resources
Acrylic test tubes 16mm, rare-earth magnets – d68/d48, enamelled magnet wire, electric meter/multimeter, 50/70L plastic container (transparent), string, fishing weight/heavy weight/rock, packing foam/small float, plastic bottle 2L/buoyant , glue gun, sandpaper.
Activities
The pupils will research different types of hydroelectricity – impoundment, diversion, pumped storage and tidal. They will create a presentation on Google Slides to present to the class.
Using what they have learnt with the workshops with Morlais as an inspiration and through their own research, pupils are to create a fully functional model of a hydroelectric wave energy generator with the use of magnets and coils following Faraday’s Law of electromagnetism.
The pupils will measure the amount of electricity generated by the artificially created waves with a multimeter.

Creating a video for others on how to create a hydroelectric wave generator and to weigh the pros and cons of building such a machine over traditional hydroelectric facilities.
