Three children show and discuss their wobbly teeth. They visit an aquarium and find out about shark teeth and talk about the differences between shark and human teeth.
After watching this clip, children could be asked to consider the difference between milk teeth and adult teeth. Through discussion it could be established that, unlike a shark, our bodies cannot replace an adult tooth once it is lost. This information could be used as a prompt to discuss with the children the factors which contribute to keeping our teeth healthy. By comparing our own teeth to that of a shark, this clip could also be used to introduce children to the idea that different animals have different types of teeth due to the varied diets they eat.
