Inspirational Quote of the Day: “Life’s battles don’t always go to the stronger or faster man. But sooner or later, the man who wins is the man who thinks he can.” – Vince Lombardi 

Objective: What does the surface of M'Kenna's small intestine look like up close compared with a healthy one?

Standards:

MS-PS1-1:

Develop models to describe the atomic composition of simple molecules and extended structures.

MS-PS1-2:

Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.

MS-LS1-3:

Use argument supported by evidence for how the body is a system of interacting subsystems composed of groups of cells.

MS-LS1-7:

Develop a model to describe how food is rearranged through chemical reactions forming new molecules that support growth and/or release energy as this matter moves through an organism.

MS-LS1-5:

Construct a scientific explanation based on evidence for how environmental and genetic factors influence the growth of organisms

To Do List:

●The digestive system is a long tube with different parts to it (Lesson 1). 

●In the small intestine, one part of the digestive system small food molecules are absorbed and large food molecules aren’t (Lesson 3).

●Absorption (in the small intestine) means that the molecules cross the lining of the small intestine and go into the body (Lesson 3).

●Fiber is not digested at all and is excreted from the body (Lesson 4). 

●Large food molecules (most complex carbohydrates, proteins, and fats) can be broken down into smaller food molecules (Lessons 5 and 6).

●In the mouth, another part of the digestive system some types of complex carbohydrates are broken down into smaller pieces through chemical reactions (Lesson 5).

●Other types of food molecules (proteins and fats) are broken down in other parts of the digestive system (stomach and small intestine) (Lesson 6).

PREPARING FOR CONSENSUS MODEL

Examine at least two other small-group models. “Take” ideas to use in your own model. “Leave” critique, based in evidence, to improve others’ models. Brainstorm parts of M’Kenna’s digestive system that you think may be functioning differently.

DEVELOPING OUR CLASSROOM CONSENSUS MODEL

As a class, develop a consensus model to describe how a healthy digestive system works. Then, discuss how you think M’Kenna’s digestive system is functioning differently than a healthy one. Consider the limitations of the classroom consensus model.
