Exploration rather than explanation. Have fun while learning science.

Make a liquid that changes colour as if by magic! And use it to test if a substance is an acid or a base.

  • Make an indicator from ordinary red cabbage leaves
  • Test some of the substances from the kitchen to find out which are bases, which are acids
  • Check out what an indicator does
  • Learn about the pH scale
