Eco Explorers: Understanding Our Planet

Grades 4–6 | Sustainability & Ecology

Become an Eco Explorer today!

Welcome students and introduce the session. Explain that they are now Eco Explorers, learning to protect our planet through observing real ecosystems.

Healthy vs. Polluted Ecosystems

Observe these two ecosystems.

• What stands out?
• How do you think human actions affect each?

Display two side-by-side images: a vibrant forest or coral reef vs. a polluted landscape or bleached reef. Ask: “What differences do you notice? How might our actions create or harm these environments?”

Ecological Challenges

Here are some real-world issues:

• Deforestation
• Plastic Pollution
• Water Scarcity
• Endangered Species

Introduce the set of Challenge Cards. Show a sample card illustrating an issue (e.g., plastic pollution). Explain that each group will receive a different card.

Group Discussion

Use your Discussion Prompts:

• What is the main issue?
• How does it impact animals, plants, and people?

Guide groups to use the Discussion Prompts Handout. Encourage each group to pick one card and discuss the two key questions.

Sustainability Solutions

Brainstorm at least three solutions for your challenge:

Hand out the Sustainability Solutions Worksheet. Remind students to think about feasibility, community impact, and creativity.

Create Your Poster

Illustrate your chosen challenge and top solution.

• Use markers and colors
• Add a short caption

Explain poster expectations: clear illustration of the issue plus the top solution. Include labels or short captions.

Reflection & Personal Pledge

Reflect on today’s learning:

• What surprised you?
• My pledge: ________

Distribute the Reflection & Pledge Template. Ask students to write one personal action they will take to help the planet.

Thank You, Eco Explorers!

Great work today!

Let’s keep our planet healthy.

Share one word to describe how you feel.

Wrap up by celebrating student pledges. Encourage ongoing eco-friendly habits and group accountability.

Discussion

Eco Explorers Discussion Guide

Use this discussion to guide students through observing ecosystems, unpacking ecological challenges, and exploring solutions. Encourage open sharing, active listening, and critical thinking.

Materials Needed

1. Observing Ecosystems (5 minutes)

  1. Display Slide 2: Healthy vs. Polluted Ecosystems.
  2. Ask the class:
    • “What differences do you notice between these two images?”
    • “How might people’s actions lead to each situation?”

Follow-Up Prompts:

  • “Can you think of a time you saw litter or pollution? How did it make you feel?”
  • “Why do you think some places become polluted while others stay clean?”

2. Sharing Ecological Challenges (10 minutes)

  1. Invite each group to pick one card from the Challenge Cards Set.
  2. Have groups share:
    • Issue: What is the main problem on your card?
    • Impact: How does it affect animals, plants, and people?

Follow-Up Prompts:

  • “What surprised you about this issue?”
  • “Who is most affected by this challenge?”

3. Brainstorming Solutions (10 minutes)

  1. Ask groups to review their ideas on the Sustainability Solutions Worksheet.
  2. Invite one solution per group to share with the class:
    • Feasibility: Why could this work in your community?
    • Impact: How big of a difference could it make?

Follow-Up Prompts:

  • “What materials or people would you need to make this happen?”
  • “How could you involve your family or friends?”

4. Personal Connection & Reflection (5 minutes)

  • “Why did you pick that word?”
  • “How can we remind each other of our pledges all year?”

Keep the discussion lively by encouraging all voices, validating ideas, and connecting student insights back to real-world actions. Let’s empower our Eco Explorers to make a difference!
