As part of British Science Week 2023, Year 6 visited Rayner Stephens High School today to take part in a lesson about acids and alkalis. They first explored what these chemicals are and then went on to look at different hazard signs for dangerous substances. They then took part in a chemistry lesson investigating different substances by adding universal indicator to test the levels of acidity in each substance using the pH scale. After this activity the children had the opportunity to each make sherbet by mixing together citric acid, bicarbonate of soda and icing sugar. We had so much fun!
