Learning Objectives

After this lesson, students will be able to:

  • define limiting population factors
  • identify environmental factors that increase and decrease populations
  • explain carrying capacity and how it impacts the population
  • discuss why populations are dynamic

Length

60 minutes

Materials

Instructions

  • Begin the lesson by asking students to discuss the advantages and disadvantages of a growing insect population.
  • Allow students to share their responses.
  • Then explain that this lesson will explore limiting factors of population growth.
  • Distribute a copy of The Limiting Factors of Population Growth. Ask a student to read aloud the 'Trying to Take Over the World' and 'What Is a Limiting Factor' sections.
  • Afterwards require students to answer the following:
    • What are limiting factors?
    • Identify factors not listed in the lesson that will allow the ant population to grow.
    • Discuss factors not listed in the lesson that minimize the ant population.
  • Ask a student to read aloud 'A Population too Large' and 'A Population too Small', then pose these discussion questions:
    • Explain what happens when overcrowding occurs as it relates to the ant population.
    • Define carrying capacity.
    • Explain why the author states that 'limiting factors can cause a population's numbers to drop so low that rapid population growth follows'.
  • Next ask a student to read aloud 'Flows Like a River' and 'Lesson Summary', then answer these inquiries:
    • Discuss why a population will remain dynamic as oppose to static.
    • Describe how humans can impact insect populations.
  • Next show the lesson quiz. Ask them to answer the questions, then review.
