Year 4 Science Experiment

16th January 2019

Today year 4 were learning about the PH balance of various liquids such as ketchup, lemon juice and Coca-Cola. Dispensing 5 drops of each into their petri dishes and using litmus paper, they analysed the changing colours of the paper to indicate PH balance, anything from dark purple to dark red. This experiment ended in some very colourful petri dishes!
