In this activity children consider how they can use wind power to charge a mobile phone and investigate circuits and how a wind turbine works.
The 36-turbine Braes O'Doune wind farm, built and operated by Airtricity, has a generating capacity of 72 megawatts, enough to supply electricity to 45,000 homes in the area. A scientist from India has developed a Micro Windmill mobile charger consisting of a small fan with blades of 10cm diameter connected to a generator with an output wire which connects to a mobile phone.
Children consider how they can use wind power to charge a mobile phone. They investigate circuits and how a wind turbine works. They form an argument to support the use of wind power.
- how to use conventional symbols for components in circuits
- how to draw electrical circuits correctly
Children will learn:
- to interpret data from a graph and draw conclusions
- to evaluate explanations
These resources were initially developed in partnership with the Centre for Science Education, Sheffield Hallam University.
