🎯 What You'll Learn

Learning Objectives

1

Understand how peristalsis moves food through the esophagus

2

Demonstrate how muscles work to move food against gravity

3

Appreciate God's intricate design in human body systems

📖 Scripture Connection

Psalm 139:14

“I will give thanks to you, for I am fearfully and wonderfully made. Your works are wonderful. My soul knows that very well.”

— Psalm 139:14 (WEB)

Highlights the incredible complexity of human body design

📦 Materials Needed

  • Digestive system model
  • Science notebook
  • Pencil
  • Plastic straw
  • Small marble or ping pong ball
📚 Step-by-Step

Lesson Plan

1Opening (5 min)

BibleMouse science explorers, today we'll discover how your body moves food without gravity!

💭 Review Question: What did we learn about digestion in the mouth yesterday?
2Teaching (15 min)

Explain peristalsis and esophagus function

📌 Key Talking Points:
  • Esophagus is a muscular tube about 10 inches long
  • Muscles contract and relax to push food downward
  • Works even when you're upside down or drinking water while lying down
💬 Discussion Questions:
  • How do you think muscles move food down?
  • Why is peristalsis important?
3Activity: Peristalsis Simulation (15 min)
demonstration

Use straw and marble to demonstrate muscle movement

📝 Instructions:
  1. Hold straw vertically
  2. Place marble at top
  3. Squeeze straw sections to move marble down
  4. Observe how pressure moves object without tilting
🔄 Variations:

Simpler: Help child squeeze straw

Challenge: Measure time and distance of marble movement

4Closing (5 min)

Recap how God designed amazing muscle movements

📝 Review Questions:
  • What makes peristalsis special?
  • How do muscles work in the esophagus?

Coming up: Tomorrow we'll explore the stomach's role in digestion

👨‍👩‍👧 For Parents
