Science Experiment

Question We were testing to find out which fizzy drinks worst for your teeth.

Prediction  We thought that the egg would bounce and the shell would come off.

Equipment needed Coke, l&P, just juice, water, 4 jars, 4 boiled eggs, 4 measuring cups

Method First you have to prepare all your equipment. Now you put the egg and the soda in a jar.  Then you put the cap on and seal it.

Results/ from most changes to least  Coke: the outside off the shell went brown and a crack went round the outside and it smelt like coca cola.  l&p: the l&P eggshell had a layer that peeled off with your finger and a crack formed and started to rot.   Just juice: the just juice had a smell that was really bad and it had rattan fully . Water: nothing had happened to the egg because water doesn't have sugar or preservatives in it.

Conclusion / Evaluation ‘Sugary drinks should come with warnings from dentists’’ - We agree/disagree with this because we agree that dentists should put ratings on it so fewer people with rotten and unhealthy teeth.
