The session covered acids and bases, polymers, surface tension and density.
|Lili explaining the science behind the experiments to the children.|
and then her very favourite experiment - cabbage water chemistry. She got to make a rainbow of colours by testing the pH of various household liquids in cabbage water.
She tested bleach, lemon juice, water, vinegar and baking soda solution.
After the activity it was such a beautiful day that Hannah and her friends ran off to play in the sandy sunshine (and brought more than a little sand home in her clothes!)
Thanks Lili for a great activity.
