This lesson plan aims to look at family structures in the UK and their influence on identity formation. Students will understand different family types, discuss the importance of family and identity, and debate whether nature or nurture has a greater impact on identity development. The lesson involves a starter activity comparing culture over time, sorting cards on UK family structures, and group presentations arguing for either nature or nurture as most influential. A plenary discussion synthesizes the best arguments from each group to build consensus on this debate.
