Egg Shells

This half term we carried out an investigation involving egg shells. Egg shells are similar to the enamel on out teeth. We wanted to find out the effects of sugar on our teeth. So we put some eggs in different liquids such as coke, water and squash and left it for a week. We were shocked by the results. The sugar free squash weakened the egg shells compared to the other liquids.
