An egg-cellent teeth experiment

In Science this week, Class 3 have been learning about teeth and why we should look after them. To investigate the impact sugar and acids has on the health of our teeth, we planned and carried out an investigation using eggs to see which liquids caused the the greatest damage to their shells. 

The children made predictions and the most popular answer was coke.

We will observe at the eggs and write up our conclusions next week.

Which liquid do you predict will have the biggest effect - coke, orange juice, vinegar, water or black tea?
