How to Skim Read the Natural Science Passage - SAT/ACT Reading

Step 1: Find the Main Hypothesis

Identifying the main hypothesis is a key step in navigating a passage efficiently. Focus on specific sections and keywords that highlight the central idea.

Words That Signal the Hypothesis

Look for terms that point directly to the main idea. These words often include:

• "hypothesis" or "hypothesized"

• "suggests" or "proposed"

• "theory" or "model"

• "claim" or "predicts"

You’ll usually find these words in two important spots:

• The first or second paragraph of the passage

• The final sentence of the introduction, just before any mention of methods or experiments

Mark these terms as you read - they act as visual cues, making it easier to revisit the main idea when needed.

Once you’ve pinpointed the hypothesis, your next task is to follow how the experiments are structured.

Following the Flow of Experiments

After identifying the hypothesis, turn your attention to markers that outline the progression of experiments. These clues help you see how the hypothesis is being tested:

Pay close attention to the opening sentence of each paragraph - it often summarizes the paragraph's purpose. Specifically, watch for:

• Independent variables (factors researchers manipulate)

• Dependent variables (what they measure)

• Predictions introduced with phrases like "we predict that" or "it is hypothesized that"

Keep in mind, the SAT Reading section is designed to assess how well you can interpret and analyze information - not your knowledge of science.

Step 2: Read Charts First

Once you've pinpointed your main hypothesis, turn to visual data like charts and graphs to either confirm or challenge it. These visuals often highlight the core findings of an experiment.

Read Graphs and Tables

To get the most out of charts and graphs, follow these steps:

• Check the title: It gives you context about the variables being measured or compared.

• Analyze the axes: Look at the labels, units, and scales to figure out:

  • What’s being measured

  • How it’s being measured

  • The range of values

• Spot patterns: Look for:

  • Overall trends

  • Group differences

  • Outliers or unusual data points

  • Relationships between variables

Here’s a quick breakdown of what to focus on:

These observations will help you interpret the data and prepare for the next step.

Quick Note Symbols

To make sense of the data quickly, use simple symbols to mark key points:

• ↑: Increasing trend

• ↓: Decreasing trend

• ★: Peak or maximum value

• ○: Minimum value

• !: Outlier or unexpected result

• →: Correlation between variables

For more complex charts with multiple variables, take these extra steps:

• Label each line or bar for clarity.

• Highlight the highest and lowest points.

• Mark intersections or overlaps.

• Circle any unexpected patterns.

Step 3: 6-Minute Reading Method

After identifying hypotheses and analyzing charts, the next step is to refine your time management with a precise reading strategy. This six-minute method helps you quickly extract essential information without needing to read every single word.

3-Part Time Split

The 6-minute method breaks your reading into three focused phases:

Set a timer for each phase to stay on track and ensure steady progress.

Mark Key Points

As you read, annotate the text to highlight critical information. Use these symbols for clarity:

• "H": Mark hypotheses and circle supporting details.

• "⇄": Indicate relationships between variables.

• "⚖": Highlight contrasting data.

• Box unfamiliar terms and underline conclusions for quick reference.

These markings help you maintain consistency between text and chart reviews, making it easier to connect information.

"As you are reading, do not hesitate to underline, circle, and make small notes in your test booklet. This type of note-taking is an efficient way to help you stay focused and on target with your pacing. Noting similarities and differences between multiple experiments will help you when it comes time to deal with the questions."

Practice Examples with Timing

Here’s how you can apply the 6-minute method to real-world examples. Let’s break it down step by step.

Biology Example: Plant Growth Hormones

1. Hypothesis Scan (90 seconds)
   Start by identifying the hypothesis: "Increased auxin concentrations promote stem elongation in seedlings."

   • Independent variable: Auxin hormone levels

   • Dependent variable: Stem length

   • Control group: Untreated seedlings

2. Chart Review (150 seconds)
   

   Analyze the growth rate graph:

   • X-axis: Time (days)

   • Y-axis: Stem length (cm)

   • Data lines: Represent control, low auxin, and high auxin conditions

   Pay attention to the relationships. For instance, peak growth occurs during days 4-7, highlighting how auxin levels impact growth rates.

3. Method & Results (120 seconds)

   • Sample size: 150 seedlings per treatment group

   • Growth conditions: 25°C with 12-hour light cycles

   • Measurement intervals: Every 24 hours over 14 days

   • Observation: Auxin concentration directly correlates with stem growth

Once you’ve practiced this, try applying the same approach to physics-related data.

Physics Example: Thermal Conductivity

1. Hypothesis Scan (90 seconds)
   Locate the hypothesis: "Metal thickness affects heat transfer rates in a predictable, inverse relationship."

   • Independent variable: Metal plate thickness

   • Dependent variable: Heat transfer rate

   • Control factors: Ambient temperature and material type

2. Chart Review (150 seconds)
   

   Study the provided data:

   Metal Thickness (mm)	Heat Transfer Rate (W/m²·K)	Time to Equilibrium (min)
   1.0	425	3.2
   2.0	212	6.5
   4.0	106	13.1

   Note the inverse relationship - thicker plates reduce heat transfer efficiency while doubling the time needed to reach equilibrium.

3. Key Details (120 seconds)

   • Temperature differential: 50°F

   • Surface area: 100 cm²

   • Material: Copper plates

   • Measurement precision: ±0.1°C

   • Observation: Plate thickness inversely affects heat transfer efficiency

"As you are reading, do not hesitate to underline, circle, and make small notes in your test booklet. This type of note-taking is an efficient way to help you stay focused and on target with your pacing. Noting similarities and differences between multiple experiments will help you when it comes time to deal with the questions."

Track Your Progress
