Digestion and teeth
In Science we have been learning about how to keep our body healthy including our teeth.
We carried out an investigation where we put eggs (our teeth) into different liquids and observed the effects of the liquids on our teeth over a week. We were horrified by some of the results. We found out that coffee stained the egg shell and turned it black where as the milk and water had no visible effects on the egg shell. Worst of all was the egg shell in the orange juice. The egg shell had started to rot disintegrate.
