ACT Science

ACT Science Question Types

ACT Science questions are categorized by their passage type. Research Summaries dominate at 45-60% of questions, followed by Data Representation at 25-35%, and Conflicting Viewpoints at 15-20%. The section tests data literacy and scientific reasoning, not science knowledge. Each guide below covers every skill tested within that passage type, with strategies and practice questions.

Data Representation

25-35%

Interpreting line graphs, bar graphs, data tables, scatterplots, and diagrams. Identifying trends, patterns, interpolation, extrapolation, and translating between representations.

Research Summaries

45-60%

Understanding variables, equipment and procedures, controls, comparing experiments, predicting modified results, evaluating experimental design, and quick math reasoning in science contexts.

Conflicting Viewpoints

15-20%

Analyzing competing hypotheses, evaluating evidence and claims, interpreting new findings, drawing warranted conclusions, identifying hidden assumptions and limitations, and model predictions.

ACT Science is a skill you build by doing.
