A description of the properties and uses of diamond, an isomer of carbon. The individual carbon atoms in diamond are shown, and it is explained how the extreme hardness of diamond makes it useful for cutting rocks and concrete. There is also a demonstration of diamond's properties as a thermal conductor.
Lead students through an investigation of the different allotropes of carbon. Challenge students to conduct a card sort in which they are provided with different properties and uses and have to match these to the structures of diamond, graphite, fullerenes and graphene.
