Investigating the effect of different liquids on our teeth

img_31001 img_30991







In science, we have used a variety of different liquids (coke, water, blackcurrant squash, milk, orange juice and vinegar) to investigate whether they have a damaging effect on our teeth.  We tested this by immersing hard boiled eggs (the shell was used to represent a tooth) into each liquid.  After a week. we observed any changes to the egg shells.

To our amazement the blackcurrant squash and the vinegar made the egg shell rubbery.  We dropped these eggs to the floor and they bounced.  Can you find out why vinegar makes an egg shell rubbery?

    I was really surprised at this experiment because I would never guess that blackcurrant would do the most damage.
