Year 4’s science experiment
Today we learnt how to carry out a practical scientific enquiry, which involves a comparative and fair test. We did this to learn more about human teeth and which kinds of liquids decay our enamel. We used boiled eggs to represent teeth. We placed one boiled egg in coke, one in water and one in orange juice. The liquid which damages and disintegrates the eggshell the most, must be the liquid which causes the most decay on our teeth.
