The Great Surface Area Showdown

Objective: Demonstrate why the small intestine is so long and folded by comparing surface area in real-world objects.

3

Open Ended

“Why do you think the small intestine is over 20 feet long? Wouldn’t a shorter one be more efficient?” Predict why the small intestine is folded and covered in villi. Lay the flat sheet of paper on the desk and measure its surface area. Crumple another sheet (like folds in the intestine) and compare how much space it now takes up. Use a sponge or paper towel to show how adding even more folds (villi & microvilli) increases absorption.
