In Primary 1 we have been learning about why it is very important to visit the dentist and also brush our teeth regularly.

We conducted an experiment using hard boiled eggs to replicate the enamel on our teeth.  We put eggs into four different liquids that we enjoy drinking.  Water, milk, coke and sugar free diluting juice.  We made predictions as to which drink we thought would be the worst for our teeth and everyone thought it would be coke!  We left them soaking for a week and today we looked at the results.

Water and milk are both good for our teeth – the eggs were not damaged in anyway.  🙂

Coke is not good for our teeth – the egg shell was stained brown in colour. 🙁

The biggest surprise was the sugar free diluting juice, not only did it discolour the egg but it also damaged the shell.  🙁  🙁

WHAT HAVE WE LEARNED?  It is okay to have “treats” and sweet drinks sometimes but if we do …  WE MUST BRUSH OUR TEETH PROPERLY!

The class then spent the morning writing instructions on how to brush your teeth properly and we also do this regularly in class.
