Acid Attack!

As part of Dental Health week, Year 6 have been looking at the science of cavities and the methods of prevention. They carried out 3 scientific experiments.

Acid Attack:
We simulated an acid attack on bones which are rich in calcium (just like our teeth). After soaking chicken bones in white vinegar overnight, we found that they were much softer the next day!

The Power Of Fluoride:  
We used two eggs for this experiment - one we soaked for a few minutes in fluoride rinse. We then put both eggs in containers of vinegar. The egg that hadn't been treated with fluoride began to bubble as the vinegar (acid) started to attack the minerals in the egg shell.

Floss is the boss: 
A great fun (messy) job. After putting on a rubber glove, we spread the fingers with jam. When thoroughly covered, we used toothpaste and a toothbrush to try and clean the jam away. The toothbrush could not remove the jam trapped between the fingers. This was a job for the floss.

Take a look at some of our pictures:-
