testing for conductivity

Notice the glasses!

Recently we did experiments on various rocks and minerals. Here is a list of our tests:
  • texture
  • color
  • luster
  • transparency
  • hardness
  • streak
  • magnetism
  • conductivity
  • florescence   
Ask your child what new information they learned about rocks and minerals. Mrs. K
