Plaque!

Room one have been learning about oral health this term. We have been discussing smart snack decisions such as fruit and vegetables that don't have much sugar. If we eat sugary foods like chocolate or cake, the bacteria in our mouths reacts to the sugar and creates plaque acid. If we don't brush our teeth twice a day, it could lead to decay and our teeth may rot. We want to keep our teeth beautiful and healthy so we don't lose them forever.
Take a look at an experiment we did using Yeast (the live bacteria) and sugar in warm water (like our mouths). The foam is like the plaque on our teeth after eating a bad snack! It was quite stinky!

Here we added the yeast to the warm water.

We added sugar to one of the glasses of yeasty water.

Look at all that 'plaque' in the glass with the sugar! 

Smart snack=almost no plaque           Bad snack=lots of fuzzy plaque!
