Warm Up and Preparation

  • Connect students to the topic by asking them to make a quick sketch of their family tree, including grandparents, aunts, etc.
  • Now have students look at their family tree and have them determine which life cycle stage their family members are in: fertilized egg, infancy, childhood, adolescence and adulthood.
  • Share answers and discuss what criteria they used to determine stages, such as age or maturity. How did they decide one was in childhood instead of adolescence, for example?
  • Start the video lesson What is a Life Cycle? - Definition, Stages & Examples and pause at 1:55.
  • Define 'life cycle' and make a chart on the board that contains columns titled: 'Number of Stages,' 'Length of Stages' and 'Notes.' Make several rows without labels.
