This concise revision lesson focuses on the relationship between the structures of diamond and graphite and their different physical properties. The PowerPoint and accompanying resources have been designed for students on the AQA GCSE Chemistry or combined science courses and is suitable for both tiers.

The lesson begins with a challenge, where the students must use their knowledge of atomic structure and the periodic table to reveal the 10-letter term, allotropes. Students will be reminded that these are different physical structures of the same chemical element, and then a series of understanding check questions challenge them to recall that the chemical element is carbon and that the carbon atoms are covalently bonded.

Moving forwards, the lesson focuses on the the number of outer electrons used in bonding in these two covalent structures and how this determines whether they have delocalised electrons and can conduct electricity. As shown in the cover image, a number of quiz competitions are used to recall key terms or to check overall understanding.
