Catching the Wind: Designing Windmills

Using the book Leif Catches the Wind, a teacher works with her second grade students to think about wind and how it can be harnessed. The teacher in this 10-minute video helps students use their prior knowledge about wind and how it blows things around. She then follows up with a quick discussion of properties of matter in order to encourage her students to think about what materials and shapes might make a sail that could effectively catch the wind. This video is part of a series of video lessons about designing windmills. Don’t miss the video that shows how to make the sail track the teacher uses to test the sails.
