Name of Activity Wind Power
Author Tufts STOMP
Keywords wind power, windmills, wind, LEGOs, pinwheels, straws, paper, brads
Subject NXTs, Non-LEGO
Grade Level K, 1, 2, 3, 4, 5, 6
Time 1 Hour Total
Brief Description Teach students about wind power, how windmills work, Cape Wind, etc. Then get the students to build windmills with Legos or make pinwheels with straws, paper, and brads.
Lesson Objectives: To learn about wind power, how windmills work, Cape Wind, etc., then to get the students to build windmills with LEGOs or make pinwheels with straws, paper, and brads.
Materials Needed: LEGOs or fan to act as wind (or you can breathe on them), wooden skewer, paper fastener (brad), construction paper, bendy straw
Preparation and Set Up: Use the overhead sheet to explain how wind power works. Then use the worksheet to get students to plan their windmill designs.
Procedure See attachment.
Extensions: If using Legos- the extension can be to make the windmill work with a motor. For classes using RCX or NXT, the windmill can have parameters for rpm.

Name of Activity LEGO Sailboats
Author Adam Glaser and Jordyn Wolfand
Keywords LEGOs, wind, wind power, vehicle, sail, sailboat, boat
Subject Non-LEGO, LEGO Building
Grade Level K, 1, 2, 3
Time 1 Hour Total
Brief Description Students will use LEGOs and other materials to build a wind-powered vehicle.
Lesson Objectives: To learn about wind power and building.
Materials Needed: LEGOs to build simple cars
Straws
Plastic bags
Tape
Fan
Preparation and Set Up: Make kits for each group with enough LEGOs to build a car, straws and plastic bags.
Arrange student into pairs.
Necessary Background Vocabulary:
Wind
Wind Power
Procedure
  1. Introduce wind power to the students.
    1. Talk about the places we find wind power.
    2. Talk about why and when wind power is useful.
      1. e.g. on the open water vs. on the highway.
  2. Tell students that they should build a car that will drive when a fan is blowing wind on it.
  3. Pass out the building kits and allow students to build their designs.
  4. Have students test their designs using a fan to simulate wind.
  5. Have students try different sized sails, wheels etc. to see what works the best.
  6. At the end of class let each student demonstrate their fan. Have a class discussion about the different designs. Ask:
    1. Which combinations worked best and why?
    2. Which combinations did not work well? why?
    3. What are some pros and cons of wind power?
    4. What are some of the forces that were affecting the cars? What types of wheels were best? Were lighter or heavier cars better? (you can talk about friction, aerodynamics, force, etc.)
