Lesson Title: Today we are learning about
What is half life?
Remember to check for PROGRESS
Focus on Knowledge, Skills and Understanding
Success Criteria: You will show your learning by...
  1. Radioactive decay is random.
  2. The half-life of a radioactive isotope is the time it takes for the number of nuclei of the isotope in a sample to halve, or the time it takes for the count rate (or activity) from a sample containing the isotope to fall to half its initial level.
  3. Students should be able to explain the concept of half-life and how it is related to the random nature of radioactive decay
  4. Students should be able to determine the half-life of a radioactive isotope from given information.
  5. (HT only) Students should be able to calculate the net decline, expressed as a ratio, in a radioactive emission after a given number of half-lives.

Keywords:
  • Division: the action of separating something into parts or the process of being separated. (1)
  • Ratio: the quantitative relation between two amounts showing the number of times one value contains or is contained within the other. (1)
  • Half-life: the time taken for the radioactivity of a specified isotope to fall to half its original value. (1)
  • Random: happening without method or conscious decision. (1)

AFL/Key Questions:
  1. How radioactive decay happen?
    Radioactive decay is a random process.
  2. What is the meaning of the term 'half-life'?
    Half life is the amount time taken for a radioacitve material to reduce it radioactive emissons by half.
  3. How is the concept of half-life related to radioactive decay?
    Radioactive activity decreasses by half at each half life.
  4. How would the half-life of a radioactive isotope be determined from given information?
    Use divisions of half to determine half lifes from given data.
  5. How would the net decline of radioactive emission after a given number of half-lives be expressed?
    Should be expressed as a ratio.
