Champions for wind; Year 8 Scalby School Lesson 1 : Renewable Energy Practical Instructions This material has been written by Matthew Docking as part of the Champions for Wind Project, made possible by funding provided by Forewind, Responsibility for the materials lies with the author and Forewind cannot accept any liability for these materials, or any consequences arising from their use 04/07/2025 1

Biomass Set up the equipment as in the picture. Measure the temperature of 10ml of water. Light the spill and use it to heat the water. (wear eye protection and take care!) Measure the temperature of the water again.

Biomass What happened to the temperature of the water? Where did the energy in the spill come from? What would happen to the water if you kept heating it? How could you use this? Is the biomass of the spill renewable? Why do you think this?

Solar Power Connect the solar cell to the multimeter and use it to measure the current and voltage produced by the cell. What happens to the current and voltage when the light is moved closer? Try and use the solar cell to light the bulb.

Solar Power What happens to the voltage as the light gets closer? Why? What happens to the current as the light gets closer? Why? Does the bulb light up? Why do you think this is? What does this tell you about the amount of solar cells and the climate needed for solar power to be useful?

Wave Power Wave power works by using the movement of water or tides to generate electricity. Where would wave power machines need to be to work best? Would they be able to work all the time? What might wave power machines do to wildlife? Why? Where does the energy in waves come from?

Wind Power Set up the equipment like in the picture. Use the hairdryer to blow the wind turbine around (care! Electricity!) What does the turbine do? How much electricity will it make?

Wind Power How could you use a wind turbine to generate electricity? How well does the wind turbine work? How could you make it work better? Would wind be a reliable source of energy? Why?

Geothermal How do you know the Blue Lagoon is hot? What can the steam be used to do? How reliable do you think this source of energy is? Where is the source of this energy? What drawbacks might there be with this source of power?

Hydroelectric pumped storage The power plant is made from two dams linked by a tunnel. The power plant in the tunnel can act as a generator (water flows from top to bottom), or a pump (water flows from bottom to top). This means that electricity can be stored. Does this plant make electricity? If it was linked with a less reliable electricity source, what could it do? Where could you build this type of powerstation?
