Lesson 7.2: The Immune System

[1]

Figure 7.2 Picture of salmonella bacteria invading human cell        

The key to a healthy immune system is its remarkable ability to distinguish between the body’s own cells, recognized as “self,” and foreign cells, or “nonself.”

Essential Questions: How does the body protect itself from pathogens?

Minnesota State Science benchmark:

9.4.4.2.2

Explain how the body produces antibodies to fight disease and how vaccines assist this process.

Lesson 7.2 Learning Targets 

Get a hard copy of this table from your teacher. Below are the learning targets you will master during this lesson.

As a pre-assessment, before the lesson begins, please circle the number that describes your current understanding of the learning target.

Before the formative assessment for this lesson, please draw a triangle around the number that describes your understanding of the learning target.

Before the summative assessment, please draw a square around the number that describes your understanding of the learning target.

1 - I have never seen this learning target before.

2 - I have seen this learning target, but I don't know what it means.

3 - I have seen this learning target, and I think I know what it means

4 - I can explain this learning target to another student.

Benchmark: 9.4.4.2.2

I can outline the three lines of defense in the human body (non-specific vs. specific defense)

Lesson 2: The Immune System Vocabulary

1. Get a hard copy of this table from your teacher. Below are the vocabulary terms you will master during this lesson.

As a pre-assessment, before the lesson begins, please circle the number that describes your current understanding of the term.

You will complete the “Definitions” and “Extra Practice” (shaded gray*) as we progress throughout the unit.

Before each formative assessment, you will reassess your understanding of the terms. When instructed, please draw a triangle around the number that describes your understanding of the term.

Finally, at the end of the unit (before the summative assessment) you will make a final assessment of your understanding of the terms.  When instructed, please draw a square around the number that describes your understanding of the term.

1- I have never seen this term before.        

2- I have seen this term but don’t know what it means.

3- I have seen this term and I think it knows what it means.

4- I can explain this term and its meaning to another student.

2. Use internet resources to find the definition of each word. Please copy and paste the link from the source you used to obtain your definition.

3. In addition to the definition you will be required to complete something additional for each term in the Extra Practice column. See the descriptions in the key below.

Sentence: Use the term properly in a complete sentence

Sketch: Draw a sketch of the term

Examples: Give examples of the term

On Your Own: Choose your own option or write an alternative definition using your prior knowledge.
