Microbiome: Lesson 2.5

10.

Living things with fewer than normal helpful bacteria in their guts can become infected more easily because there is more food and space available for harmful bacteria.

Microbiome: Lesson 2.5

Remember, the senator is claiming that tiny microorganisms are too small to affect human health. Based on this claim, he wants to cut funding for fecal transplant research.

Activity 3

Microbiome: Lesson 2.5

Let’s use an everyday example to think about making convincing arguments.

Is this argument convincing?

Why or why not?

Microbiome: Lesson 2.5

This argument has a claim and it has some evidence.

What is the argument missing?

Activity 3

Microbiome: Lesson 2.5

Remember, part of creating a strong argument is making your reasoning clear by showing how the evidence connects to the claim.

Microbiome: Lesson 2.5

Many people forget to explain their thinking clearly in an argument. To help us, we’ll use a graphic organizer called the Reasoning Tool. Let’s use the cola argument as an example.

Activity 3 - Screen 1

Microbiome: Lesson 2.5

For the rest of this lesson, we will work on creating an argument in support of Subclaim 1.

25 of 38

Microbiome: Lesson 2.5

Activity 3 - Screen 1

We have three strong pieces of evidence that support this subclaim.

The first is our data about Patient 23’s health before and after the fecal transplant.

Activity 3 - Screen 1

We also have important evidence from the experiment on mice, which showed that mice with normal amounts of bacteria in their guts were less likely to get sick from Salmonella.

Activity 3 - Screen 1

Finally, we have evidence from “The Human Microbiome” article, which tells us bacteria are living things that need food and living space to survive.

Microbiome: Lesson 2.5

Activity 3 - Screen 1

In preparation for writing our arguments, we are going to discuss these pieces of evidence.

You’ll work in pairs to practice explaining why each piece of evidence matters and how it supports the subclaim. First we’ll review the directions.

Next, we will use the Reasoning Tool to prepare an argument about Patient 23. It will help us explain how each piece of evidence supports Subclaim 1.

We'll review how to use the tool and then fill in the first row together.

Activity 4

Microbiome: Lesson 2.5

In the first column, you'll see the different pieces of evidence that support the subclaim.

In the middle column we’ll explain how the evidence supports the claim.

Then, we will write all or part of the subclaim in the column on the right.
