  4. Let students complete the following list for each vitamin:
    • Chemical explanation
    • Discovery history
    • Deficiency disease and symptoms

Teacher Tips

  • The molecular expressions images have no scientific value, but they are a wonderful collection of art created under the microscope.
  • You may teach this class in a computer lab or in a classroom with only a teacher's computer/projector.

More Ways

  • You may want to use the Molecular Expressions art collection to start a discussion about the microscopic world.
