Blowing in the Wind

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.

Description

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.

Learning Objective:

-    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
