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?
This week we have been finding out facts about the fantastic author Roald Dahl.In class we have began sharing the book George’s Marvellous Medicine which has inspired us to concoct our own set of ingredients for a medicine we may wish to try out on someone to rid them of their not so pleasant ailments. Among them we had,Reece’s Rocket medicine, Theo’s Magical Medicine and many more.
