Eggsellent Science

In the last week of the Autumn term Year 3-4 created an enquiry to discover which liquid caused the least damage to teeth. Using an egg to represent a tooth we used 6 glass jars, boiled eggs and different liquids we stored these for a week. These included orange juice, water, milk, coke, vinegar and orange squash with sweetner.

The children discovered that the vinegar and coke changed the colour of the eggs to brown with a film over it. The orange juice had a sticky film and the orange squash broke the shell and left a white residue. Only the milk and water left the eggs undamaged.

Below are pictures of the children observing and discovering the effects.
