Teeth

Year 4 received a letter from the Tooth Fairy asking them to investigate why the enamel on some child's teeth was becoming worse. We used eggs to carry out our investigation and observed what happened to the shell when they were left in different liquids. We used undiluted squash, milk, water, coke, vinegar and orange juice. Once the investigation was finished, the children wrote back to the tooth fairy explaining the results and ideas of what she could do about the problem.
