Lesson 6

Lesson Objectives...

• Analyze and interpret data to identify patterns in the amount that certain food molecules (complex carbohydrates, proteins, and fats) decrease and other food molecules (glucose, amino acids, and fatty acids) increase as they move through different organs in the digestive system. 

• Analyze and interpret these data as evidence that the digestive system is a system of interacting subsystems composed of organs that each perform different functions.

Resources for Lesson 6...

Food Molecule Data for a Healthy Person

Analyze the amount of food molecules as they move through a healthy persons body.  Record in your science notebook whether the food molecule increases (↑), decreases (↓), or stays the same (＝) from the previous location to the new location.  

Patterns in Food Molecules

Think about the graham cracker moving through the different organs of the digestive system. How do these patterns help explain why the amount of one type of molecule (e.g., a protein) might be decreasing by the same amount that another type of molecule (e.g., amino acids) is increasing?

Answers to Lesson 6 - Student Notebook

What we figured out this lesson...

• Certain food molecules are broken down by different portions of the digestive system.

• Different organs in the digestive system perform different functions.
