I divide class into 2 groups and they have to search internet and provided resources on graphite or diamond and answer specific questions. They then pick a lab partner from other group and coach each other. Once this is done I give them a 6 mark question: explain why graphite conducts electricity but diamond does not, which they self assess. Very pacey lesson with excellent outcomes.

pupils work in groups of 4. 1st give them 4 cards with correct atomic structure, including electron shells and tell them to come up with rules. then give them 4 cards with incorrect atomic structure to test their rules. then they have to see if they need all the rules.... works a treat! please comment and rate if you use, thanks
