ACT Science Conflicting Viewpoints Point of Agreement vs Disagreement Between Scientists

What This Is and Why It Matters for the ACT

Conflicting Viewpoints: Point of Agreement vs Disagreement Between Scientists appears on the ACT Science section. This topic is crucial as it tests your ability to analyze and interpret scientific information, identify patterns, and make informed decisions. It appears on every Science test and is typically of intermediate difficulty.

Key Concepts (What You Must Know)

• Scientific Method: A systematic process used to develop and test scientific knowledge.
• Data Interpretation: The ability to analyze and understand data presented in various formats, including graphs, charts, and tables.
• Scientific Evidence: Information gathered through observation, experimentation, and measurement to support or refute a scientific claim.
• Critical Thinking: The ability to evaluate information, identify biases, and make informed decisions.
• Key Vocabulary:
  • Hypothesis: An educated guess that can be tested through experimentation.
  • Variable: A factor that can be changed or controlled in an experiment.
  • Control Group: A group in an experiment that does not receive the treatment being tested.

Step-by-Step Strategy for This Topic

1. Read the passage carefully: Identify the main question and the key information presented in the passage.
2. Identify the variables: Determine which variables are being tested and how they are related.
3. Look for patterns and trends: Analyze the data presented in the passage to identify patterns and trends.
4. Evaluate the evidence: Determine the strength of the evidence presented in the passage and identify any potential biases.
5. Make an informed decision: Based on the information presented, make an informed decision about the main question.
6. Check your work: Verify that your answer is consistent with the information presented in the passage.

How It’s Tested on the ACT

The ACT Science section typically presents a passage with accompanying data, graphs, and charts. You will be asked to analyze the information and answer questions based on the data presented. The questions may ask you to identify patterns, trends, and relationships between variables, as well as evaluate the strength of the evidence presented.

Common Distractors: Be careful of questions that ask you to make assumptions or jump to conclusions based on limited information. Also, be aware of questions that ask you to evaluate the credibility of the source, rather than the evidence presented.

Common Mistakes & Exam Traps

• The mistake: Overlooking key information in the passage.
• Why it happens: Rushing through the passage or not reading carefully.
• How to avoid it: Take your time and read the passage carefully, identifying key information and variables.
• Exam board insight: The ACT Science section is designed to test your ability to analyze and interpret scientific information, so make sure to carefully evaluate the evidence presented.
• The mistake: Misinterpreting data or graphs.
• Why it happens: Not understanding the data or not reading the labels.
• How to avoid it: Take your time and read the labels carefully, identifying the variables and relationships presented in the data.
• The mistake: Not considering alternative explanations.
• Why it happens: Not thinking critically or not considering multiple perspectives.
• How to avoid it: Take your time and evaluate multiple perspectives, considering alternative explanations and potential biases.
• The mistake: Not evaluating the strength of the evidence.
• Why it happens: Not understanding the scientific method or not evaluating the credibility of the source.
• How to avoid it: Take your time and evaluate the evidence carefully, considering the strength of the evidence and the credibility of the source.

Practice Questions (3-5 questions)

Question 1: A study was conducted to investigate the effect of exercise on heart rate. The data presented in the table shows the average heart rate of a group of participants before and after exercise.

What can be concluded about the effect of exercise on heart rate?

A) Exercise has no effect on heart rate.
B) Exercise increases heart rate.
C) Exercise decreases heart rate.
D) The data is insufficient to determine the effect of exercise on heart rate.
E) The data is inconsistent with the hypothesis that exercise increases heart rate.

Answer: B) Exercise increases heart rate.

Explanation: The data presented in the table shows a clear increase in heart rate after exercise, indicating that exercise has a positive effect on heart rate.

Question 2: A study was conducted to investigate the relationship between the amount of fertilizer used and the yield of a crop. The data presented in the graph shows the yield of the crop in relation to the amount of fertilizer used.

What can be concluded about the relationship between the amount of fertilizer used and the yield of the crop?

A) There is no relationship between the amount of fertilizer used and the yield of the crop.
B) The yield of the crop increases with the amount of fertilizer used.
C) The yield of the crop decreases with the amount of fertilizer used.
D) The data is insufficient to determine the relationship between the amount of fertilizer used and the yield of the crop.
E) The data is inconsistent with the hypothesis that the yield of the crop increases with the amount of fertilizer used.

Answer: B) The yield of the crop increases with the amount of fertilizer used.

Explanation: The data presented in the graph shows a clear positive relationship between the amount of fertilizer used and the yield of the crop, indicating that the yield of the crop increases with the amount of fertilizer used.
