The heart is a powerful muscle about the size of your fist. It works like an incredible pump, sending blood to every part of your body.

📌 Key Talking Points:
  • Heart has four chambers: two atria and two ventricles
  • Blood moves in a continuous cycle through arteries and veins
  • The heart beats approximately 100,000 times per day
💬 Discussion Questions:
  • Why do you think God designed the heart to work continuously?
  • How is the heart like a pump?
3Activity: Heart Pump Simulation (15 min)
demonstration

Use red and blue yarn to demonstrate blood flow through the heart

📝 Instructions:
  1. Divide yarn to represent oxygenated and deoxygenated blood
  2. Create a 'heart' using hands to show pumping motion
  3. Trace blood's path through the body
🔄 Variations:

Simpler: Use simplified heart diagram from BibleMouse Printables Library

Challenge: Research heart's electrical conduction system

4Closing (5 min)

Review key heart facts and marvel at God's design

📝 Review Questions:
  • What makes the heart special?
  • How does blood move through the body?

Coming up: Tomorrow we'll explore blood vessels - the highways of the human body!
