Sample OAE Integrated Science Practice Questions

Try these sample questions to test your OAE Integrated Science exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Which investigation best isolates fertilizer concentration as the cause of bean plant growth differences?

A.Use the same plant type, soil, light, and water while changing only fertilizer concentration

B.Use different plant species in each fertilizer group

C.Let each group choose its own watering schedule

D.Measure only the tallest plant in each group

Explanation: A controlled investigation changes one independent variable and keeps likely confounding variables constant. Replication and consistent measurements make the fertilizer-growth relationship more defensible.

2Which statement best describes a scientific theory?

A.A guess that has not yet been tested

B.A broad explanatory framework supported by repeated evidence

C.A fact that can never be revised

D.A rule based only on mathematical symbols

Explanation: Scientific theories explain patterns across many observations and experiments. They are durable when evidence is strong but can be refined when better evidence appears.

3On a product-versus-time graph, what represents average reaction rate over an interval?

A.The y-intercept only

B.The color of the plotted points

C.The slope over that interval

D.The number of tick marks on the axis

Explanation: Rate is change in product divided by change in time, which is the slope of the graph over the interval. A steeper positive slope means faster product formation.

4Which practice is safest when heating a volatile organic solvent?

A.Heat it in a sealed container

B.Smell the vapor directly

C.Put on goggles only after boiling begins

D.Use a fume hood and avoid open flames

Explanation: Volatile solvents can produce flammable and harmful vapors. Ventilation and ignition control reduce inhalation and fire risks before heating starts.

5Repeated length measurements are 12.4, 12.5, 12.4, and 12.5 cm, but the accepted value is 13.1 cm. How should they be described?

A.Precise but not accurate

B.Accurate but not precise

C.Both accurate and precise

D.Neither repeatable nor systematic

Explanation: The measurements cluster closely, showing precision. They are consistently far from the accepted value, so they lack accuracy and may reflect calibration error.

6Which question is most testable in a science investigation?

A.Are algae interesting?

B.How does nitrate concentration from 0 to 20 mg/L affect algal growth over 10 days?

C.Should all lakes look clear?

D.Why is nature complicated?

Explanation: A testable question identifies variables, a measurable outcome, and conditions. Nitrate concentration, algal growth, and time frame can be investigated with data.

7An article claims a supplement prevents all viral infections. What should a scientifically literate reader check first?

A.Whether the article uses confident language

B.Whether customer testimonials are emotional

C.Whether controlled studies with methods and data support the claim

D.Whether the claim matches personal hopes

Explanation: Scientific claims require evidence from appropriate methods, not tone or preference. Extraordinary health claims need transparent data and independent scrutiny.

8How can students improve reliability in a pendulum experiment?

A.Use a different mass for every length

B.Release the pendulum from random angles

C.Record only the trial closest to the expected value

D.Run multiple trials at each length and average the periods

Explanation: Repeated trials reduce the influence of random error and reveal measurement consistency. Keeping other conditions constant protects the comparison of length and period.

9A data point is far outside the pattern of the other trials. What should students do first?

A.Investigate possible procedural or recording error before excluding it

B.Delete it because all outliers are mistakes

C.Change nearby values so the trend is smoother

D.Use only the outlier because it is unusual

Explanation: Outliers should be examined with documentation. They may reflect error, natural variation, or a phenomenon worth investigating.

10What is the best description of a scientific model?

A.An exact copy of a natural system

B.A simplified representation used to explain or predict phenomena

C.A replacement for evidence

D.Something used only when direct observation is impossible

Explanation: Models such as atomic models and climate models organize complex relationships. Their assumptions and predictions must be tested against evidence.

OAE Integrated Science Study Tips from Top Performers

1Use the official Integrated Science (024) framework as the primary checklist and track progress by competency 0001 through 0016.

2Prioritize Physical Science because it accounts for 37% of the assessment score and spans chemistry, physics, energy, waves, circuits, and electromagnetism.

3Practice calculations with units and formula setup; the exam provides reference materials, but it still expects fluent application.

4For Life Science, connect cellular processes, genetics, evolution, organism systems, and ecology instead of memorizing isolated vocabulary.

5For Earth and Space Science, practice interpreting processes over time: plate motion, rock formation, weather systems, climate controls, Moon phases, and stellar evolution.

6For Nature of Science, focus on variables, controls, uncertainty, safety, models, data displays, evidence quality, peer review, and science-technology-society reasoning.
