🎯 What You'll Learn

Learning Objectives

1

Understand how organisms are interconnected in food webs

2

Create a detailed food web for a specific ecosystem

3

Predict ecological consequences of removing key species

📖 Scripture Connection

Genesis 1:31

“God saw everything that he had made, and behold, it was very good.”

— Genesis 1:31 (WEB)

Highlights the intricate, interconnected design of God's creation in ecosystems

📦 Materials Needed

  • Colored paper
  • Markers
  • Scissors
  • Tape or string
  • Science notebook
  • BibleMouse Ecosystem Picture Cards
📚 Step-by-Step

Lesson Plan

1Opening (5 min)

Discuss how every creature plays a unique role in God's design of ecosystems

💭 Review Question: What did we learn about energy transfer in ecosystems yesterday?
2Teaching (12 min)

Explore complex interactions within food webs

📌 Key Talking Points:
  • Food webs show how energy and nutrients move between organisms
  • Removing one species can dramatically impact the entire ecosystem
  • Each organism has a critical role in maintaining balance
💬 Discussion Questions:
  • How might removing a predator affect other animals?
  • What makes an ecosystem healthy?
3Activity: Ecosystem Food Web Creation (18 min)
project

Students will create a detailed food web for a chosen ecosystem

📝 Instructions:
  1. Select an ecosystem from BibleMouse Ecosystem Picture Cards
  2. Identify all organisms in that ecosystem
  3. Create paper cutouts representing each organism
  4. Connect organisms with strings/arrows showing energy flow
  5. Label each connection with type of relationship
🔄 Variations:

Simpler: Focus on fewer organisms, use pre-printed organism cards

Challenge: Add complexity by including decomposers and multiple energy pathways

4Closing (5 min)

Share food webs and discuss ecosystem complexity

📝 Review Questions:
  • What surprised you about your ecosystem's connections?
  • How do organisms depend on each other?

Coming up: Tomorrow we'll explore how matter cycles through ecosystems
