KS3 Science- Red Cabbage Ph Indicator Experiment!
Our KS3 Chemistry students have been taking a closer look at Acids and Alkalis by investigating and exploring the pH scale using red cabbage indicator.
Using the home learning pack, the students were able to use a red cabbage indicator strip to test the pH values of various substances, such as lemonade, bleach, washing powder, and others.
The children explored neutralisation reactions by using red cabbage indicator to test the pH of vinegar and bicarbonate of soda before and after they react.
The indicators helped tell whether the substance was acid, alkaline, or neutral. Students got to see the indicators turn a range of colours, depending on the pH of the substance then discussed the results.
