Learning Objectives

1

Measure and compare lung capacity using water displacement method

2

Understand how exercise impacts breathing and lung function

3

Appreciate God's intricate design of the human respiratory system

Job 33:4

The Spirit of God has made me, and the breath of the Almighty gives me life.

Job 33:4 (WEB)

Highlights how breath is a divine gift and demonstrates God's intentional design of human respiratory function

📦 Materials Needed

  • Large clear plastic container
  • Water
  • Measuring cup
  • Straw
  • Towels
  • BibleMouse Respiratory System Worksheet

Lesson Plan

1Opening (5 min)

Today's BibleMouse lesson explores how wonderfully God designed our lungs! We'll measure our lung capacity and see how amazing our breathing system is.

💭 Review Question: What did we learn yesterday about how the diaphragm helps us breathe?
2Teaching (12 min)

In our BibleMouse curriculum, we're discovering the incredible complexity of how we breathe. Lung capacity varies between people and can change with exercise.

📌 Key Talking Points:
  • Lungs are like special balloons that expand and contract
  • Everyone's lung capacity is slightly different
  • Exercise can temporarily increase lung capacity
💬 Discussion Questions:
  • Why do you think athletes might have larger lung capacities?
  • How does deep breathing help our bodies?
3Activity: Lung Capacity Water Displacement Experiment (18 min)
hands-on

Students will measure their lung capacity by displacing water using a controlled breath through a straw

📝 Instructions:
  1. Fill large clear container with water
  2. Mark initial water level
  3. Take a deep breath and blow through straw into water
  4. Measure how much water is displaced
  5. Record results in BibleMouse Respiratory System Worksheet
  6. Repeat after light exercise to compare
🔄 Variations:

Simpler: Help child measure and record results directly

Challenge: Graph results and calculate average lung capacity

4Closing (5 min)

Reflect on how precisely God designed our respiratory system

📝 Review Questions:
  • What did you learn about lung capacity?
  • How does exercise change our breathing?

Coming up: Tomorrow we'll explore how oxygen moves into our blood through tiny air sacs called alveoli

Teaching Notes

📚 Background:

Lung capacity naturally varies and can be influenced by age, fitness, and genetics

💡 Teaching Tips:
  • Encourage gentle, safe breathing during experiment
  • Use this as opportunity to discuss healthy lifestyle
  • Remind child that God values our whole person - body and spirit
🤔 Common Struggles:

Children might get frustrated if their lung capacity seems smaller than siblings or friends

👀 Signs of Understanding:

Understanding that everyone's body is uniquely designed

Extension Activities

  • Research lung capacity of different animals
  • Create a poster about respiratory system for BibleMouse science fair
  • Practice deep breathing exercises as a family

Ready for Tomorrow?

Great job completing today's lesson!
