Download a larger image of the astronomical clock and share the photo with your class. Then discuss the following:
  • This is one of the oldest mechanical clocks in the world. Imagine life without any clocks. Make a list of all of the ways that you have depended on a clock today.
  • The clock kept track of the Earth and its relationship with the other planets. Investigate why people in medieval times would find that important.

  • Using construction paper and markers, develop a new design for a clock, one that is radically new and meets your needs and the needs of your friends. It can’t simply be a smartphone.
