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

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?

Discuss with the person behind youKAP Wrap The 3-Step Method for Conflicting
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
![Page 18: Unit 4 Conflicting Viewpoints. Lesson 4A Questions About One Viewpoint](https://reader031.vdocuments.site/reader031/viewer/2022032201/56649d345503460f94a0b37d/html5/thumbnails/18.jpg)
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
![Page 20: Unit 4 Conflicting Viewpoints. Lesson 4A Questions About One Viewpoint](https://reader031.vdocuments.site/reader031/viewer/2022032201/56649d345503460f94a0b37d/html5/thumbnails/20.jpg)
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.

about the second viewpoint.

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!
