'Don't Call the Doctor!'

As part of our Healthy Living topic we have looking at how to keep our teeth healthy.  We began an experiment last week to find out which drink damaged our teeth most.  We made predictions, wrote up the experiment and did observations.

We put a hard boiled egg in an equal amount of a different liquid - Ribena, milk, fresh orange juice, coca cola, vinegar and water.

Today was the reveal - which drink did the most damage?  Were our predictions correct?

 

Gloves on ready!  First we looked at the Ribena - what had happened?

 

 

Elise - putting her hand into coagulated milk!  The smell was yucky!

 

 

And the results?  The orange juice destroyed the egg shell (almost like the enamel which covers out teeth); the coca cola stained the shell but it the stain wiped off and the milk destroyed the inside of the egg - like the dentine in our teeth.

 

All of us said we would brush our teeth more often after seeing what could happen to them!
