Class 4 Science

Class 4 have been learning about the human digestive system in their science lessons this term.  As part of this, they planned and carried out an investigation to find out how different drinks can affect our teeth.

They used hard boiled eggs to represent our teeth and put each of them in a different liquid for a week.  The liquids included milk, water, coke, squash and vinegar.  Today the class opened the jars containing the eggs and liquids to see the results.  There were a few surprises including eggs which had gone soft and some which had changed colour!
