Digestive System Stations Lab – Enzymes, Diffusion, Villi Surface Area & Candy Dissolving Investigation

$6.50

A Hands-On, Multi-Station Lab on Digestion, Nutrient Breakdown, Enzyme Function & Intestinal Surface Area.

Turn your digestion unit into a high-energy, hands-on exploration with Digest This!, a 5-station lab where students model, test, measure, compare, and discover how food is broken down and absorbed. Students rotate through activities that bring abstract biological processes to life — including an escape-style organ ordering challenge, a saliva vs. water candy dissolving experiment, enzyme memory-match cards, a diffusion manipulation model, and a villi surface area ruler investigation.

This resource includes two versions of Station 1 depending on whether you want students to open a real locked box of candy (Version 1) or unlock access through you (Version 2).

Students love the challenge and movement — teachers love that this lesson teaches digestion through experience, not memorization.

What’s Inside

✔ Station 1 — Organ Dissection Escape Code
Order digestive organs correctly to unlock the next station

✔ Station 2 — Saliva vs. Water Candy Dissolving Test
Experiment, time dissolving rates, analyze enzymes

✔ Station 3 — Diffusion & Membrane Permeability
Hands-on visuals with silly visual comparisons, cut-outs, and modeling with props

✔ Station 4 — Enzyme Memory-Match Card Game
Match amylase/lipase/protease/lactase/pepsin to correct biomolecules & subunits

✔ Station 5 — Villi & Surface Area Math Lab
Measure smooth vs. villi-lined intestine models to calculate surface area increase

✔ Full Teacher Key Included
Answer explanations reinforce content, reduce grading time

Grade & Course Recommendation

Best Fit Grades

Grades 6–10

Ideal Courses

  • Middle School Life Science

  • Biology

  • Human Body / Anatomy units

  • Health Science Foundations

  • Special Education & co-taught classrooms (hands-on + low-text accessible)

Cross-Curricular Connections & Extensions

Math Integration

  • Students calculate villi-mediated surface area change (Station 5) using measured ratios

Chemistry & Food Science

  • Enzyme specificity + substrate breakdown illustrated through memory-match cards (Station 4).

Experimental Design

  • Station 2 emphasizes fair test conditions, variables, and enzyme effect discussions

Extension Ideas

  • Students design a “new digestive adaptation” to increase absorption and justify its function.

  • Create a CER comparison of diffusion before vs. after digestion in Station 3.
