This activity requires participants to design a handheld windmill that can lift weights. It will challenge participants' engineering creativity and ability to manipulate independent and dependent variables. For a written lesson and instructions for this activity, visit the KidWind REcharge lab activities page at https://www.kidwind.org/activities/recharge-labs.
The Kansas Energy Program put together the video below to show how the activity might work if participants are allowed to use whatever materials they have on hand. From our experience, it just adds to the challenge!
