Name of Activity Mini Turbines
Author Jay Clark
Keywords mini turbines, turbines, construct, wind, wind farm, alternative energy
Subject Non-LEGO
Grade Level K, 1, 2, 3, 4, 5, 6
Time 1 Hour Total
Brief Description Students build mini turbines and the class splits into two teams to construct competing wind farms. The farm with the most “energy generation” wins.
Lesson Objectives: To introduce students to alternative energies.
Materials Needed: - Paper
- Pencils
- Push pins
- Puddy
- Two fans
Procedure Lesson How does a car drive? energy! We use energy all the time… and where does the energy from cars come from? gasoline! what’s wrong with using gasoline as energy? there is a finite amount of it on the earth, It can run out! also, it is harmful to the environment. What are some sources of energy that don’t run out?

  • The sun (for all intents and purposes)
  • wind
  • water

A lot of time, effort, and resources are being put into developing alternative, renewable energy sources.   How can we harness the wind’s power? Turbines!   Today we’ll be making turbines. What are some things to think about when designing and installing a turbine?

  • Making it high enough so it is not affected by the boundary layer friction caused by the ground.
  • Making the base strong enough to counteract the moment caused by the wind.
  • Making the base strong enough to counteract the moment caused by the spinning blades.

Activity Hand out materials, and have students construct pinwheels according to the directions in the attached document. When all the pinwheels are completed, split the class into two teams to construct competing wind farms. For a successful farm, each turbine should get its own free stream of wind, and should not catch any of the turbulence coming off of a turbine near it.
