Today 4 th “A” & 4th “B” did a dentist’s experiment!!!.
We wanted to prove how the toothpaste protects our teeth and the importance of keeping our teeth clean and healthy.

We followed these steps:

We waited for the results and…
After two or three minutes one egg started to bubble as the vinegar (an acid) attacked the minerals in the egg shell.
Which egg do you think started to bubble?

The egg that was not brushed with fluoride toothpaste bubbled and lost its colour.

We went through an amazing experience !!!!!! Everybody enjoyed it and learnt something very important about our teeth.

Do you take care of your teeth? Think on it.

Hope you like our experiment!!!!!
