Science: We are chemists

Tuesday 28 February 2023

We have continued to be chemists in our science learning and conducted an experiment that produced a chemical reaction. The children mixed two liquids – vinegar and warm milk. The vinegar altered the acidity in the milk and made it curdle. The children sieved the liquid to retrieve the curdled mixture and then moulded and dried it. This chemical reaction had created  a type of plastic. The children recognised that this was an irreversible change as it could not be returned to its original state. We were quite amazed by the whole process and also quite overwhelmed by the weird smell that the mixture made!

Help at home: Could you recreate this experiment at home so your child can talk you through the process? Can they use any scientific vocabulary in their explanation?
