Student consolidate their understanding of the heating and cooling unit by completed a circus of timed Level 7 questions in groups. Keywords: convection, conduction, insulation, emitting radiation.

Russell the Wilderness Explorer wants to earn his expansion and contraction badge, can you help? Students become adventure explorers and earn badges by defining key terms from earlier on in the unit. Students watch classic demonstrations (could be completed as class experiments) and video clips from the movie to help them explain why particles expand when heated and contract during cooling. Higher students are introduced to the idea of density before answering and evaluating an assessed question. I used this lesson very successfully in an Ofsted observation. Students find this lesson incredibly engaging- I thought I'd share this resource for free due to the Disney copy right issues etc.
