As it is Oral Hygiene Week at CPS, we conducted an experiment called 'Plaque Attack' to mimic what plaque does to our teeth.
These were our ingredients and equipment.We needed warm water, yeast and sugar.
We had one cup marked 'Sugar' and one marked as 'No Sugar'
We added one teaspoon of sugar to our cup marked 'Sugar' along with yeast and warm water.
Our cup marked 'No Sugar' contained only yeast and warm water, so we could see the effect of sugar in our other cup.
As we waited and observed both cups we wrote down what we could see happening in each cup. After 10 minutes we were surprised to find that the cup with sugar had gone all frothy and brown compared to the cup with no sugar. This showed us how plaque bacteria is caused by sugar and a reaction occurs very fast.
Here are some photos of us writing down our observations:
