SCIENCE OBSERVATIONS - Digestive System
Class: Year 4 Year: 2020 - 2021
We are learning about the digestive system in science and the first part of the digestive system is what happens inside our mouth. We have looked at teeth and today we were given the challenge to brush our teeth well. To test how good we were, Mrs Twinn gave us a disclosing tablet which we had to chew. It made our mouths turn purple and blue and we also had pink tongues! The disclosing tablet showed any plaque which was still in our mouths so we could see how good we were at brushing our teeth. We had to rebrush our teeth again to get rid of the colour. Some of us went home with pink tongues!
