What happens when your stomach's acid level is too high and the mucus protection is gone? Students control gastric acid levels, enzyme activity, and mucus protection in an interactive simulation — watching what breaks down food and what damages the stomach lining. They discover why the stomach doesn't destroy itself and what goes wrong when it does. Scaffolded for SPED and ICT classrooms.

📦 WHAT YOU GET (6 files, 22+ pages):

🎨 THE SLIDES: Every slide pairs the concept with a visual, color throughout. The lesson follows a consistent structure — Hook, Learning Target, Success Criteria, Key Vocabulary, Word Breakdown, What It Means, In Real Life, Turn & Talk.
