Feel The Power Feel The Power Presentation Transcript

  • FEEL THE POWER Standard 3.3.8 Investigate and describe how moving air and water can be used to run machines like windmills and waterwheels.
  • TERMS
    • Matter
      • anything that has mass and takes up space
    • Mass
      • a measure of how much matter is in an object
  • MATERIALS
    • 2 pieces of construction paper
    • Scissors
    • A hole punch
    • A push-pin
    • A pencil with an eraser
    • Markers or crayons
  • HOW TO MAKE A PINWHEEL HTTP://WWW.ENCHANTEDLEARNING.COM/CRAFTS/PINWHEEL/
    • Start by making two square pieces of paper. To start making a square, put the two pieces of paper together. Fold the corner of the pieces of paper over as shown.
    • To finish making the squares, cut off the small rectangles, forming two squares (which are already folded into a triangle).
    • Fold the triangle in half. Unfold the paper
    • If wanted, decorate one side of each sheet of paper.
  • CONT.
    • Put the undecorated sides of the paper together. Make four cuts along the fold lines - about halfway to the center.
    • Punch four holes in the pinwheel, one at each corner.
    • Gently gather each of the four points (with a hole) to the center. (Be careful not to crease the paper.)
    • Push a push-pin through the four punched holes through the center of the pinwheel to attach the pinwheel to the side of a pencil's eraser.
  • ACTIVITY WITH PINWHEEL
    • Have students hold the pinwheel, blow gently on it.
    • Show students the picture of the windmill again.
    • Explain how the parts of the windmill that turn, like the pinwheel, are connected to other parts that move as the arms turn.
    • Explain that windmills can generate electricity.
    • Discuss how energy from the wind turns the blades of the windmill and can eventually be transferred to electrical energy.
  • QUESTIONS TO THINK ABOUT
    • What happened to the pinwheel when you blew on it?
    • How are windmills powered?
    • How did you use the power of the wind to turn the pinwheel?
    • Now finish, by sharing your thoughts on the next sheet.
    • Then, enjoy the pinwheel that you just made!
