             The Discovery Project

Students will work in small groups to research and to recreate the *experimental instruments used to make significant discoveries about the atomic structure of atoms.

Each group will:

  1. be assigned a specific experimental instrument.
  2. plan and acquire the necessary building materials.
  3. build a replica of the instrument.
  4. research the instrument:
  • Who used the instrument?
  • What was discovered?
  • When and where was the instrument used?
  • How did the discovery effect our concept of atomic structure?
  1. make a poster or PowerPoint displaying their      research information.
  1. present an oral report about their instrument.
