Lesson Objectives Understand the difference between fission and fusion. Recognise that ‘cold fusion’ is a disputed claim made by some scientists. Understand why fusion research is an international joint venture.

fission • fusion • energy • Joules Success Criteria Grade E Grade C Grade A Describe the difference between fission and fusion Describe a nuclear bomb as an ‘out of control’ chain reaction Understand the conditions needed for fusion to take place Recall the ‘cold fusion’ controversy Describe how nuclear fusion releases energy Explain why ‘cold fusion’ is still not accepted by most scientists Key Words: fission • fusion • energy • Joules

Use pages 260-263 in the textbook Nuclear Fusion Use pages 260-263 in the textbook Get into groups of 2: 1 person researches Fusion and its difference to Fission 1 person researches Cold Fusion You must teach your partner about the information you discovered.

Plenary Mastermind In turn, each pair take to the front of the class. They must field 3 questions from the class.
