🎯 Master the ACT Science Section
The ACT Science test doesn't just test science knowledge - it tests your ability to interpret data, analyze experiments, and think like a scientist. This module will teach you both the science content AND the critical thinking skills you need to excel.
📊 Data Representation
15-20% of questions
Interpret graphs, tables, and diagrams
🔬 Research Summaries
45-55% of questions
Understand experimental design and results
⚡ Conflicting Viewpoints
15-20% of questions
Compare and contrast scientific theories
📈 Skills by Target Score
Choose your target score range to focus on the most important skills for your goals:
🟢 Basic Skills (ACT 16-19)
Foundation📊 Reading Simple Graphs
Science Content: Understanding x and y axes, identifying trends in line graphs
Test Strategy: Always check units and scale before interpreting data
📋 Basic Data Tables
Science Content: Reading rows and columns, finding specific values
Test Strategy: Use your finger to track rows/columns to avoid mistakes
🔍 Identifying Variables
Science Content: Independent vs. dependent variables
Test Strategy: Ask "What's being changed?" (independent) vs "What's being measured?" (dependent)
🟡 Intermediate Skills (ACT 20-23)
Building Up📈 Trend Analysis
Science Content: Direct vs. inverse relationships, exponential growth
Test Strategy: Look for keywords: "increases", "decreases", "remains constant"
🧪 Experimental Design
Science Content: Control groups, constants, hypothesis testing
Test Strategy: Identify what's being tested and what stays the same
📊 Interpolation & Extrapolation
Science Content: Predicting values within and beyond data range
Test Strategy: Follow the pattern, don't overthink it
