Inspirational Quote of the Day: “Always turn a negative situation into a positive situation.” – Michael Jordan 

Objective: What is the function of the digestive system, and how is M'Kenna's digestive system different? 

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

NAVIGATION

Review M’Kenna’s symptoms and the investigations we have completed, thus far, to figure out how M’Kenna can experience symptoms in so many different parts of her body.

WHAT CAN WE EXPLAIN NOW?

Look back at the initial models we developed to explain M’Kenna’s symptoms. Consider the investigations we have done since then. Compile all of the pieces of our models from our Progress Trackers into one model.

GOTTA-HAVE-IT CHECKLIST

Develop a Gotta-Have-It Checklist to list the important ideas we have figured out so far that we need to include in our new models to answer the question, “How does a healthy digestive system work?”

Gotta Have it Checklist

●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).

DEVELOP MODELS IN SMALL GROUPS

Work in small groups to develop a model to explain, “How does a healthy digestive system work?” Use your Gotta-Have-It Checklist to help. Check off ideas on the list that you used or did not use to develop the model.
