Teeth Experiment

On Monday 20th April we did an experiment. We got four cups

and put an egg in each one and filled the cup up with full fat

coke, orange juice, milk and water then you leave it 24 hours

or longer.

The  eggs are teeth and we want to see what has

happened to each egg. 

Hypothesis

I think the full fat coke is going to rot the egg the most.

            RESULTS

           The orange juice made the egg shell go white . Its the acid

           that made the egg shell go white The coke made the egg

          shell go bigger and browner. The   milk just made it sticky

          and the water did nothing, except make it wet.

Conclusion

The water is the best for your teeth and the orange juice is the worst for your teeth.
