Key Concepts

  • Biotic and Abiotic Factors
  • Levels of Ecological Organization (Individual, Population, Community, Ecosystem, Biosphere)
  • Interdependence within Ecosystems

Learning Objectives

  • Define ecology and differentiate between biotic and abiotic factors.
  • Describe the different levels of ecological organization and provide examples of each.
  • Explain how living organisms interact with each other and their environment within an ecosystem.

Educator Instructions

  • Introduction (5 mins)
    Begin by asking students what they think of when they hear the word 'ecology'. Briefly introduce the video and its purpose: to provide a foundation for understanding ecology.
  • Video Viewing (10 mins)
    Play the Khan Academy video "Ecology introduction | Ecology | Khan Academy". Instruct students to take notes on key terms and concepts.
  • Discussion (15 mins)
    Lead a class discussion based on the discussion questions below. Encourage students to share their observations and interpretations of the video's content.
  • Interactive Exercise: Ecosystem Mapping (15 mins)
    Divide students into small groups and assign each group a local ecosystem (e.g., schoolyard, park, pond). Have them create a map of their assigned ecosystem, identifying and labeling biotic and abiotic factors, as well as potential interactions between them.

Interactive Exercises

  • Ecosystem Mapping
    Students create a map of a local ecosystem, identifying and labeling biotic and abiotic factors and their interactions.

Discussion Questions

  • What are some examples of biotic and abiotic factors in your immediate environment?
  • How do the different levels of ecological organization relate to each other?
  • How can changes in abiotic factors affect the biotic factors in an ecosystem? Give an example.
  • Why is it important to study Ecology?

Skills Developed

  • Critical Thinking
  • Observation
  • Collaboration
  • Scientific Communication
