Science Lesson Plan: Ecosystem

Grade Level: 3
Length: 30 Minutes
Subject: Science
Topic: Ecosystem

Objectives

By the end of this lesson, students will be able to:

1. Define what an ecosystem is.
2. Identify the components of an ecosystem.
3. Understand the relationship between living and non-living things in an ecosystem.

Materials Needed

• Whiteboard and markers
• Pictures of different ecosystems (e.g., forest, desert, ocean)
• Ecosystem handout with definitions and images
• Pencils and paper for students

Introduction (5 minutes)

• Start the lesson by asking students if they know what an ecosystem is.
• Write down their responses on the whiteboard.
• Define an ecosystem as a community of living organisms (plants, animals, and microorganisms) interacting with their environment (air, water, and soil).

Direct Instruction (10 minutes)

What is an Ecosystem?

• An ecosystem includes both biotic (living) and abiotic (non-living) components.
• Explain the terms:
  • Biotic factors: Plants, animals, fungi, bacteria
  • Abiotic factors: Sunlight, temperature, water, minerals

Types of Ecosystems

• Show pictures of different ecosystems and briefly describe each one:
  • Forest Ecosystem: Trees, animals like deer and birds, various plants.
  • Desert Ecosystem: Cacti, lizards, snakes, limited water.
  • Ocean Ecosystem: Fish, seaweed, coral, salty water.

Guided Practice (10 minutes)

• Divide students into small groups and give each group an ecosystem picture.
• Ask them to identify the biotic and abiotic factors in their assigned ecosystem.
• After a few minutes, have each group present their findings to the class.

Independent Practice (5 minutes)

• Distribute the Ecosystem handout with definitions and images.
• Ask students to complete the following tasks on a sheet of paper:
  1. Draw one biotic factor and one abiotic factor from any ecosystem.
  2. Write one sentence about how these factors interact with each other.

Conclusion (5 minutes)

• Recap the definition of an ecosystem and the importance of the relationship between living and non-living things.
• Ask students to share their drawings and sentences if time allows.

Homework

Tasks:

1. Define the word "ecosystem" in your own words.
2. List three biotic and three abiotic factors found in an ecosystem of your choice (e.g., forest, desert, ocean).
3. Write 2-3 sentences describing how one biotic and one abiotic factor interact in your chosen ecosystem.

Correct Answers:

1. Ecosystem: A community of living animals and plants interacting with the environment.
2. Example answers (these can vary based on student choice):
   • Forest:
     • Biotic: Trees, birds, deer
     • Abiotic: Sunlight, rain, soil
   • Desert:
     • Biotic: Cacti, lizards, snakes
     • Abiotic: Sand, sunlight, little water
3. Example of interaction: In a forest, trees (biotic) provide shade and habitat for birds (biotic), while the soil (abiotic) provides nutrients for the trees to grow.
