ACT Science Science Strategy No Outside Knowledge All Answers in the Passage

What This Is and Why It Matters for the ACT

Science Strategy — No Outside Knowledge: All Answers in the Passage appears in the Science section of the ACT. This topic is a common challenge for students, as it requires reading and interpreting data within the passage to answer questions. It appears on every Science test and is typically considered an intermediate-level topic.

Key Concepts (What You Must Know)

• Data representation: Understanding various types of charts, graphs, and tables.
• Research summaries: Identifying main points and supporting details in scientific research.
• Conflicting viewpoints: Recognizing and analyzing different perspectives on a scientific topic.
• Scientific vocabulary: Familiarity with key terms such as hypothesis, experiment, and data analysis.

Step-by-Step Strategy for This Topic

1. Read the passage carefully: Identify the main topic, key findings, and any supporting data.
2. Understand the question type: Determine if the question is asking for data interpretation, research summary, or conflicting viewpoints.
3. Eliminate wrong answers: Look for incorrect or unsupported information in the answer choices.
4. Check your work: Verify that your answer is supported by the passage.
5. Manage your time: Allocate 2-3 minutes per question, and use the remaining time to review and check your work.

⚠️ Don't overthink the question: Focus on the information provided in the passage, and avoid making assumptions.

How It’s Tested on the ACT

The Science section of the ACT includes data representation, research summaries, and conflicting viewpoints. Questions may include: * Graphs and charts with missing data or labels * Research summaries with main points and supporting details * Conflicting viewpoints with different perspectives on a scientific topic * Common distractors: Be cautious of answer choices that:
+ Misinterpret data or statistics
+ Overlook or misrepresent supporting details
+ Present conflicting information as fact

Common Mistakes & Exam Traps

1. Mistake: Overlooking supporting details.
   • Why it happens: Misreading the passage or rushing through the question.
   • How to avoid it: Carefully read the passage and identify key supporting details.
   • Exam board insight: The ACT penalizes students for not providing sufficient evidence to support their answer.
2. Mistake: Misinterpreting data.
   • Why it happens: Failing to understand the data representation or statistics.
   • How to avoid it: Take the time to understand the data and statistics presented in the passage.
   • Exam board insight: The ACT expects students to accurately interpret data and statistics.
3. Mistake: Failing to recognize conflicting viewpoints.
   • Why it happens: Not recognizing or analyzing different perspectives on a scientific topic.
   • How to avoid it: Carefully read the passage and identify different viewpoints.
   • Exam board insight: The ACT expects students to recognize and analyze conflicting viewpoints.

Practice Questions (3-5 questions)

Question 1
The graph below shows the relationship between temperature and plant growth.

[Insert graph]

A) The temperature at which plant growth is maximized is 25°C.
B) The temperature at which plant growth is minimized is 10°C.
C) The temperature at which plant growth is unaffected is 20°C.
D) The temperature at which plant growth is severely inhibited is 30°C.
E) The temperature at which plant growth is optimal is 15°C.

Answer: C) The temperature at which plant growth is unaffected is 20°C.

Explanation: The graph shows that plant growth is unaffected at 20°C, which is the temperature at which the curve is flat.

Question 2
The table below shows the results of an experiment on the effect of light on plant growth.

A) The experiment shows that plant growth increases with increasing light intensity.
B) The experiment shows that plant growth decreases with increasing light intensity.
C) The experiment shows that plant growth remains constant with increasing light intensity.
D) The experiment shows that plant growth is unaffected by light intensity.
E) The experiment shows that plant growth is severely inhibited by high light intensity.

Answer: A) The experiment shows that plant growth increases with increasing light intensity.

Explanation: The table shows that plant growth increases with increasing light intensity, from 10 cm to 20 cm to 30 cm.

Question 3
The passage below discusses the benefits of a new type of solar panel.

"The new solar panel is more efficient than traditional solar panels and can generate more electricity per hour. It is also more durable and can withstand harsh weather conditions."

A) The new solar panel is more efficient than traditional solar panels.
B) The new solar panel is less efficient than traditional solar panels.
C) The new solar panel is more durable than traditional solar panels.
D) The new solar panel is less durable than traditional solar panels.
E) The new solar panel is unaffected by harsh weather conditions.

Answer: A) The new solar panel is more efficient than traditional solar panels.

Explanation: The passage states that the new solar panel is more efficient than traditional solar panels.
