Exploring Ecosystems: A 5th Grade Science Adventure

Objective

Students will understand the concept of ecosystems and food chains, identifying relationships between organisms and their environment. They will engage in a hands-on warm-up activity, participate in a guided lesson, and complete an independent task to demonstrate their understanding.

Materials/Resources

• Warm-Up Activity:

  • A bag or box (opaque)
  • Various natural items (leaves, rocks, feathers, small toys representing animals, etc.)

• Main Lesson:

  • Whiteboard and markers
  • Printed handouts with examples of food chains
  • Chart paper and colored markers for group work

• Independent Task:

  • Paper and colored pencils or crayons

Lesson Plan Procedure

Opening/Lesson Hook

• Warm-Up Activity: "What’s in the Bag?"

  • Place various natural items in an opaque bag.
  • Students take turns reaching into the bag without looking and feel an object. They must describe it using adjectives and guess what it is.
  • Discuss how different items represent different parts of an ecosystem (e.g., a feather could represent a bird).

Guided Practice

• Introduction to Ecosystems and Food Chains:

  • Explain what an ecosystem is (a community of living organisms and their environment).

  • Introduce food chains using a simple example:

    • Example: Grass → Rabbit → Fox

      • Discuss how energy flows from the grass (producer) to the rabbit (herbivore) and then to the fox (carnivore).

  • Use the whiteboard to draw the food chain and label each part.

  • Ask students to identify other animals that might fit into this food chain.

Independent Practice

• Task: Create Your Own Food Chain

  • Students will either:

    • Draw a Basic Food Chain: Illustrate a food chain involving at least three organisms.
    • List Animals from Different Ecosystems: Write down three animals from a forest, desert, and ocean ecosystem, and identify their roles (producer, consumer, decomposer).

  • Encourage creativity in their drawings and encourage them to think about the interactions in their chosen ecosystems.

Differentiated Activities

• Below Grade Level:

  • Provide pictures of organisms for students to label and arrange into a simple food chain.
  • Pair students with a peer to discuss their choices and brainstorm ideas together.

• At Grade Level:

  • In addition to drawing or listing, students could write a short paragraph explaining the importance of each organism in their food chain.

• Above Grade Level:

  • Challenge students to create a more complex food web that includes multiple food chains and interactions between different ecosystems, explaining the relationships in a brief report.

Closing

• Allow a few students to share their food chains or lists with the class.
• Reinforce the idea of interconnectedness in ecosystems and the importance of each organism in maintaining balance.

Extension Activities or Sample Questions

• Formative Assessment Questions:

  • What is an ecosystem? Can you give an example?
  • Describe the role of a producer in a food chain.
  • What would happen if one organism in a food chain disappeared?

• Summative Assessment:

  • Create a poster displaying a food web that includes at least five organisms, their roles, and how they are connected.

Reflection

• After the lesson, the substitute teacher can reflect on student engagement and understanding based on their participation in activities and completion of tasks.
• They can also note any questions that arose during discussions to inform future lessons on ecosystems.
