Lesson Title: Today we are learning about
What is the difference between fission and fusion?
Remember to check for PROGRESS
Focus on Knowledge, Skills and Understanding
Success Criteria: You will show your learning by...
  1. Nuclear fission is the splitting of a large and unstable nucleus (eg uranium or plutonium).
  2. Spontaneous fission is rare. Usually, for fission to occur the unstable nucleus must first absorb a neutron.
  3. The nucleus undergoing fission splits into two smaller nuclei, roughly equal in size, and emits two or three neutrons plus gamma rays. Energy is released by the fission reaction.
  4. All of the fission products have kinetic energy.
  5. The neutrons may go on to start a chain reaction.
  6. The chain reaction is controlled in a nuclear reactor to control the energy released.
  7. The explosion caused by a nuclear weapon is caused by an uncontrolled chain reaction.
  8. Students should be able to draw/interpret diagrams representing nuclear fission and how a chain reaction may occur.
  9. Nuclear fusion is the joining of two light nuclei to form a heavier nucleus.

Keywords:
  • Nuclear weapon: a bomb or missile that uses nuclear energy to cause an explosion. (1)
  • Chain reaction: the self-sustaining fission reaction spread by neutrons which occurs in nuclear reactors and bombs. (1)
  • Spontaneous: performed or occurring as a result of a sudden impulse or inclination and without premeditation or external stimulus. (1)
  • Fission: division or splitting into two or more parts. (1)

AFL/Key Questions:
  1. What is meant by the term 'nuclear fission'?
    The process of splitting a nucleus is called nuclear fission.
  2. When does Spontaneous fission occur?
    Spontaneous fission is rare. Usually, for fission to occur the unstable nucleus must first absorb a neutron.
  3. What happens to a nucleus undergoing fission?
    The nucleus undergoing fission splits into two smaller nuclei, roughly equal in size, and emits two or three neutrons plus gamma rays. Energy is released by the fission reaction.
  4. What type of energy do all fission products have?
    All of the fission products have kinetic energy.
  5. What starts the chain reaction?
    The neutrons may go on to start a chain reaction.
  6. How is a chain reaction controlled?
    The chain reaction is controlled in a nuclear reactor to control the energy released.
  7. How is the explosion of a nuclear weapon caused?
    The explosion caused by a nuclear weapon is caused by an uncontrolled chain reaction.
  8. What is nuclear fusion?
    Nuclear fusion is the joining of two light nuclei to form a heavier nucleus.
