We planned and carried out an investigation to explore what would happen to egg shells when they were put in different liquids, we use and drink. We wanted to find out which one might do the most damage to our teeth.
We made predictions, set up our investigation then waited to find out what would happen next. After a few days we observed what had happened to the egg shells, discussed the predictions we had made and evaluated our investigation and fair testing.
We all thoroughly enjoyed this investigation and were shocked by our results.
