Lesson 2

Lesson Objectives...

• Analyze and interpret data to identify patterns in how the structures of the digestive system and relative amounts of substances in a food sample appear in a healthy person as compared to in M’Kenna.

Resources for Lesson 2...

Structures of the Digestive System...

M'Kenna's Endoscopy Report...

Studying Endoscopy Images...

Analyzing Data with the I2 Strategy...

First, make observations:

• Draw an arrow to something you notice in the graphs.

• Write "What I see" (or WIS), then write your observation in a complete sentence.

• Share your observations.

Now, Interpret your observations:

• Think about what each observation means.

• Write "What it means" (or WIM), then add your explanation next to the observation.

What we figured out this lesson...

• The digestive system is made up of different parts called organs.  The different organs have similarities and differences in their structures.

• M'Kenna's small intestine doesn't look the same as a healthy one.

• In a healthy person, many different substances in a graham cracker decreases as they travel through the small intestine.

• Some substances in M'Kenna's small intestine decrease, but others do not decrease as much compared to a healthy person.
