Wind turbine from a fan

Students build a model of a turbine with a small motor and check which shape of blades gives the most current.

Steps

1. We prepare a DC motor with an LED.
2. Groups design cardboard blades of different shapes and numbers.
3. We place the turbines in front of a fan and look at the brightness of the LED.
4. We talk about wind farms in the Baltic Sea.

Tip: Ready-made educational kits for building a turbine cost a few dozen zlotys.

Materials needed

• Educational wind turbine kit (1 per group)
