Doing a simple machines or Rube Goldberg challenge in your physics class? Look no further. Have students scan this AR trigger with the APP Layar, it will take them to an iMovie on my You Tube Channel which asks them to find different examples of student created Rube Goldberg projects on the Internet and describe what the objective of the Rube Goldberg designs were. Perhaps you could use this in your physics, engineering, or technology class.
