On Thursday morning the pupils worked accurately and precisely to make red cabbage indicator and use it to test whether different substances were acidic or alkali.
We found out that fruit is slightly acidic and toothpaste is slightly alkali (which is why toothpaste neutralises the acid in your mouth!)
Dr Ritchie challenged the children to train their families once they got home. Please send us photos of your home experiments and let us know what you discover!
