ACT: Research Summaries and Conflicting Viewpoints

ACT Science Format

40 questions, 35 minutes. Seven passages:

  • 3 Data Representation (graphs/tables)
  • 3 Research Summaries (experiments)
  • 1 Conflicting Viewpoints (opposing theories)

Research Summaries

What to Look For

  1. Purpose: What question is the experiment answering?
  2. Variables: Independent (changed), dependent (measured), controlled (constant)
  3. Procedure: What steps were followed?
  4. Results: What patterns appear in the data?

Common Question Types

  • If the experiment were repeated with a change, what would happen?
  • What is the relationship between X and Y?
  • Which variable was controlled?

Conflicting Viewpoints

Strategy

  1. Read the introduction (shared facts)
  2. Read each viewpoint and note its KEY CLAIM
  3. Identify where they AGREE and DISAGREE
  4. Answer questions about each viewpoint separately first

Data Interpretation Tips

Reading Graphs

  • Always check axis labels and units
  • Look for trends: increasing, decreasing, constant

Reading Tables

  • Find the pattern as one variable changes
  • Compare rows/columns systematically

ACT Tip: The ACT Science section tests reading and interpretation more than science knowledge.

📚 Practice Problems

1Problem 1easy

❓ Question:

Students tested how temperature affects plant growth. They grew plants at 15°C, 20°C, and 25°C and measured height after 2 weeks. What is the independent variable?

💡 Show Solution

Solution:

Independent variable = what the experimenter changes

In this experiment:

  • Changed: Temperature (15°C, 20°C, 25°C)
  • Measured: Height (dependent variable)
  • Kept same: Time (2 weeks), type of plant, etc. (controls)

Answer: Temperature

ACT Tip: Independent comes FIRST (cause), dependent comes SECOND (effect)

2Problem 2medium

❓ Question:

Why would researchers perform an experiment 3 times instead of just once?

💡 Show Solution

Solution:

Multiple trials serve several purposes:

  1. Reduce random error - one trial might have flukes
  2. Calculate averages - more accurate results
  3. Increase reliability - consistent results across trials
  4. Detect anomalies - spot outliers

Answer: To increase reliability and reduce the impact of random error

ACT Tip: More trials = more reliable data!

3Problem 3hard

❓ Question:

An experiment tested 3 fertilizers (A, B, C) on tomato plants. All plants received the same amount of water and sunlight. What is the purpose of keeping water and sunlight constant?

💡 Show Solution

Solution:

These are control variables (kept constant).

Purpose:

  • Ensure the only difference is the type of fertilizer
  • Allows fair comparison between groups
  • If water varied, couldn't tell if growth differences were from fertilizer or water

This is called a "controlled experiment"

Answer: To ensure that any differences in plant growth are due to the fertilizer type and not other factors

ACT Tip: Control variables eliminate confounding factors!
