Mississippi Science HAP.13.8
The Standard
- HAP.13
- Students will investigate the structures and functions of the digestive system, including the cause and effect of diseases and disorders.
Enrichment: Use an engineering design process to develop effective treatments for gastrointestinal diseases (e.g., methods to regulate stomach acids or soothe ulcers, treat food intolerance, and dietary requirements/modifications). *

What This Standard Means
What Students Need to Do
- Students choose a digestive problem, such as acid reflux or lactose intolerance. They set a goal and limits, design a treatment or diet change, test a model or compare evidence, then revise their plan.
What Mastery Looks Like
- A student can explain why a proposed change fits the symptoms and meets safety, cost, and nutrition limits. They compare options using test results or package labels and explain what they would change next.
Common Misconceptions
- Students may treat all stomach pain as excess acid or assume antacids cure ulcers. They may mistake a vinegar test for proof that a treatment works in people.
How to Assess It
- Exit ticket: A student with lactose intolerance needs a lunch drink with calcium. Choose a drink, explain how you would check its lactose, calcium, and price, then name one change you would make if it costs too much.

Ways to Teach It
Add equal amounts of two antacids to separate cups of dilute vinegar, then compare pH strips after two minutes and discuss what the model cannot show.
Ask pairs: Which lunch drink suits a student with lactose intolerance who needs calcium, and what label evidence supports your choice?
Give teams reflux treatment cards and patient constraints, then have them rank options and revise their choice when a new constraint appears.
Use grocery flyers to plan a lactose-free lunch under $6, check product labels for calcium, and revise one choice.
