The current science topic in phase 2 is all about our teeth, food and health. During the first lesson of scientific investigation we put 4 eggs into 4 different containers with four different liquids. The eggshells were representing our teeth enamel. We were going to check which drink: water, milk, cola or orange juice was going to damage the eggshell the most. We left them sealed for 7 days to await the results. The children were very excited, checking the containers every day to see if they could observe any changes!
