Lesson Plan

1Opening (5 min)

Today's BibleMouse lesson explores how calcium makes our bones strong and flexible!

💭 Review Question: What did we learn yesterday about different types of joints?
2Teaching (12 min)

Calcium is like the 'building blocks' of our skeletal system

📌 Key Talking Points:
  • Calcium provides bone strength and structure
  • Our bodies continuously replace bone tissue
  • Nutrition plays a crucial role in bone health
💬 Discussion Questions:
  • What foods do you know contain calcium?
  • Why do you think bones need to be strong?
3Activity: Vinegar Bone Experiment (18 min)
hands-on experiment

Remove calcium from a bone to demonstrate its importance

📝 Instructions:
  1. Place clean chicken bone in jar
  2. Cover completely with white vinegar
  3. Wait 24-48 hours
  4. Observe and record changes
  5. Gently try to bend bone
🔄 Variations:

Simpler: Parent assists with observation

Challenge: Create detailed scientific drawing of bone changes

4Closing (5 min)

Reflect on experiment and bone health

📝 Review Questions:
  • What happened to the bone in vinegar?
  • Why is calcium important?

Coming up: Tomorrow we'll explore how bones connect and create our body's framework
