Lesson Plan

1Opening (5 min)

Recap yesterday's lesson about stomach digestion and preview today's exploration of nutrient absorption

💭 Review Question: What did we learn about how the stomach breaks down food?
2Teaching (15 min)

Detailed explanation of small intestine function and villi

📌 Key Talking Points:
  • Villi are tiny finger-like projections that increase absorption surface area
  • Surface area allows maximum nutrient transfer into bloodstream
  • Each villus contains blood vessels for direct nutrient transport
💬 Discussion Questions:
  • Why might God design the small intestine with such a complex structure?
  • How do villi help us process the food we eat?
3Activity: Surface Area Calculation Challenge (15 min)
hands-on measurement

Students will measure and calculate small intestine surface area using paper folding and measurement techniques

📝 Instructions:
  1. Unfold paper multiple times to simulate villi complexity
  2. Measure total surface area created
  3. Compare to actual small intestine surface area
🔄 Variations:

Simpler: Use pre-measured paper sections

Challenge: Calculate percentage difference between model and actual intestinal surface area

4Closing (5 min)

Summarize key learning points about small intestine absorption

📝 Review Questions:
  • What makes villi so special?
  • How does God's design help us process nutrients?

Coming up: Tomorrow we'll create a complete digestive system model showing how all parts work together
