Primary 4 and 5 were scientists today. We wanted to find out how different drinks effected our teeth so we set up an experiment to investigate this.
We used a hard boiled egg to represent a tooth, then placed one egg into a glass of each of the following drinks: coke, Diet Coke, milk, diluted cordial, fruit juice and vinegar.
We predicted what might happen and will check on our eggs tomorrow and again after Christmas.
