Unit 4 Conflicting Viewpoints

Lesson 4A

Questions About One Viewpoint

Bell workThinking KAP As you are walking through the Lacandon Rainforest, you

start getting thirsty. You head toward a stream and area about to take a cool, refreshing drink when one of your friends says, "Don't drink the water! It may be unhealthy."

You stop to ask what could be wrong, when another friend says, "I'm sure it's fine. We're not near any cities, so it can't be polluted."

Which friend do you think is correct? What evidence could you use to demonstrate your opinion?

FYI: Strategy Instruction Introduction to Conflicting Viewpoints

Conflicting Viewpoints passages present two different explanations for the same evidence. Just as two different detectives working on the same case may interpret the evidence in different ways, two scientists may draw different conclusions from the same data. You will be asked to clarify each person's viewpoint, give information that will support or disprove a viewpoint, and compare the ideas of the two people.

Notes: The 3-Step Method for Conflicting Viewpoints Step 1: Summarize the passage and scan the figures.

Summarize the introduction carefully and underline keywords.

Step 2: Answer the easier questions. Answer questions about details in the introduction. Summarize the first viewpoint and answer questions about

the first viewpoint. Summarize the second viewpoint and answer questions

about the second viewpoint.

Step 3: Answer the harder questions. Answer questions about multiple viewpoints.

Notes: What's in the Introduction? Sometimes there are questions based solely on

the introductory paragraph. Because the viewpoints offer conflicting evidence, the only way you can answer this type of question is to look at the background information in the introduction.

Look for keywords in the introduction which: state the conflict to be discussed state evidence that is already known and is agreed

upon in both viewpoints Try It Out! P.143

Try It Out! P.143

Notes:One Viewpoint at a Time Each viewpoint will provide a different

explanation for the question or problem presented in the introduction. When you read a viewpoint, underline keywords to answer the following questions: What is the writer's theory? What evidence does the writer present?

The Second Viewpoint

When you read the second viewpoint, treat it as an entirely new idea, and answer all questions that are just about the second viewpoint separately.

The 3-Step Method for Conflicting Viewpoints Step 1: Summarize the passage and scan the figures.

Summarize the introduction carefully and underline keywords.

Step 2: Answer the easier questions. Answer questions about details in the introduction. Summarize the first viewpoint and answer questions about

the first viewpoint. Summarize the second viewpoint and answer questions

about the second viewpoint.

Step 3: Answer the harder questions. Answer questions about multiple viewpoints.

Viewpoints tells you to answer questions about just one viewpoint before answering questions about both.

Why is this a better idea than answering the questions in the order they are printed?

Thinking KAP

As you are walking through the Lacandon Rainforest later in the day, you tell your friends about the herpetologist in the group and explain that she studies reptiles and amphibians. You explain that you made a graph for her that showed that there were more species of frogs sighted in the morning than around noon.

One friend suggest that frogs do not like the hot sun, and hide in the shade during the afternoon. Another suggests that your tour group was making more noise in the afternoon and scared the frogs away. A third friend suggests that as you walked through the rainforest you entered areas with different amounts of water, sunlight, and insects, and some of them held more frogs than others.

Which friend do you think is correct? What evidence could you use to demonstrate your opinion?

Lesson 4BAnalyzing the Passage

Notes: Strategy InstructionEvaluating Evidence

Easier questions will ask you to identify details from the viewpoints, harder questions may ask you to speculate on additional evidence that would weaken or strengthen a theory

There are three main types of harder questions on the ACT. determine whether new evidence supports or

contradicts a theory predict the results of an experiment

Notes:Evaluating Evidence Read the experiment or results and underline

keywords.

Look for similar keywords in the viewpoints, and reread the sentence.

Determine whether the ideas in the question are the same as or the opposite of the ideas in the viewpoint.

Keep in Mind: Keywords may appear in questions or answers.

Supporting and Contradicting Data

Scientific theories are based upon support from many experiments. These same experiments can be used to disprove other competing theories. Many ACT questions will ask you to determine whether a specific piece of evidence supports or weakens the ideas presented in the viewpoints. To do this, use Evaluating Evidence to address each piece of new evidence.

Try It Out! P.157

Compare and Contrast

All of the questions that apply to one scientist can also be applied to two scientists. These questions will either ask you to determine which scientist supports a specific idea, or identify which theory would be strengthened or weakened by a new piece of evidence.

Try It Out! P. 158

Predicting Results

Scientific theories are useful to scientists because they not only explain the causes of experiments or data that are already available, but help predict the outcome of new experiments. Evaluating Evidence can be used for predicting the results of experiments as well. Simply treat each prediction as if it were evidence, and compare it to the evidence in the viewpoint.

The 3-Step Method for Conflicting Viewpoints Step 1: Summarize the passage and scan the figures.

Summarize the introduction carefully and underline keywords.

Step 2: Answer the easier questions. Answer questions about details in the introduction. Summarize the first viewpoint and answer quesitons about

the first viewpoint. Summarize the second viewpoint and answer questions

about the second viewpoint.

Step 3: Answer the harder questions. Answer questions about multiple viewpoints.

__answer questions comparing both viewpoints__read the introduction__read the second viewpoint__answer questions about the second viewpoint only__read the first viewpoint__answer questions about the introduction__answer questions about the first viewpoint only

2. When solving problems that involve evidence, first ____ in the question, then compare them to specific ____ in the viewpoint. Finally, determine if the pieces of evidence are ____ or ____ .

Lesson 4C:

General Test-Taking Strategies

Class Demonstration:Strategy Instruction Relax!

The Silent Stretch (every few pages) While you count slowly to 15, stretch your shoulders

back. At the same time, stretch your arms down toward the

floor as far as they will go. As the same time, stretch your legs straight out in front

of you, keeping them close to the floor. Take deep breaths as you count. Breathe in, 1...2...3,

breathe out, 4...5...6, breathe in, 7...8...9, breathe out, 10...1...12 - all the way to 15.

Relax!

You should learn to do this so quietly that no one in the room notices you doing it. When you open your eyes and go back to the test after the Silent Stretch, you will feel refreshed!

Get Ready

What you don't want to do right before a big test is cram. You've learned a lot of science this year. You've also learned a lot of test taking strategies. You are totally prepared, and you don't need to cram. You also don't need to worry when you are taking the test - just remember the 3-Step Method for ACT Science!

Try It Out!

Keep in Mind

if you are worried about the test, talk to your family or your teacher about it.
