Till eulenspiegel Till eulenspiegel Presentation Transcript

  • Using a Story: Till Eulenspiegel
    • Till Eulenspiegel is a folk tale character.
    • In this story he walks on a tightrope over the lake and amuses the audience.
    • The local kids shake the rope and he falls into the lake.
    • What can he do?
  • The story as a branch: Till Eulenspiegel walks on the tightrope in balance The kids shake the rope Till Eulenspiegel falls into the lake
  • The story as a branch: WHY ? Because his center of gravity was above the rope Because he lost his balance WHY ?
  • What is this “ center of gravity ” ?
    • Let us make an experiment to demonstrate:
    • Materials:
    • 1 Styrofoam egg
    • 3 wood skewer
    • 2 beads
    • Insulating tape
    • Decoration objects
  • Follow the instructions:
    • Insert one wood skewer through the Styrofoam egg from up to down, as shown in the picture.
    • Insert two wood skewers into the sides of the Styrofoam egg, as shown in the picture.
    • Put the beads on the side skewer.
    • Use the Insulating tape to set the beads on the end of the skewer.
    • Change the position of the central skewer to change the balance of the “ acrobat ” .
    • Find the best balanced point and let it stand.
  • Back to the Injection: He takes shoes from the kids and hold them below the rope He walks on the rope without falling down The center of gravity is below the rope
