We had an exciting Tuesday afternoon where we revealed the results of our tooth enamel investigation.
Last week, Year 4 placed hard boiled eggs into glass jars and poured variety of liquids over the eggs to investigate the effect these liquids would have on the shell. We used eggs because the shell is similar to the enamel on our teeth. The children were able to use what they already knew and the information provided by the dental nurse (who paid us a visit a couple of weeks ago) to make a prediction about which liquids would damage the shell.
For the past week, the children have been observing what they think was happening to the shells and have been patiently awaiting the day we could take the eggs out of the jars. Finally we were able to take the eggs out and observe what had happened. The results were very interesting and some were a bit surprising.
Ask your child what they found out and which liquids could damage the enamel on your teeth.
