Compare High-Scoring vs. Flawed Physics RQs

Below are examples of evaluated RQs from recent Physics IAs. Review the strengths and weaknesses to understand the scoring criteria, and feel free to evaluate your own RQ using the form above.

10/10 Score
How does the mass m (0.05, 0.10, 0.15, 0.20, 0.25 kg) attached to a 0.50 m simple pendulum affect the damping time constant τ (s), as determined from an exponential fit to the amplitude decay measured with a motion sensor in air?
Strengths:
5

Clear link between an independent variable (mass) and a dependent variable (damping time constant).

Weaknesses:
0
10/10 Score
How does temperature T (20 °C–60 °C in 5 °C steps) of a glycerol sample affect its dynamic viscosity η (Pa·s), as determined from the terminal velocity of a 5.00 mm steel sphere using a falling‑sphere viscometer in a vertical cylindrical container?
Strengths:
4

Clear identification of the independent variable (temperature) and dependent variable (dynamic viscosity) with units.

Weaknesses:
0
1/10 Score
Is Physics important?
Strengths:
2

The question is concise and clearly focuses on physics as the subject of inquiry.

Weaknesses:
6

Specify the independent variable with a measurable quantity and units (e.g., 'the amount of time spent studying physics (h)').

1/10 Score
How does Physics affect things?
Strengths:
2

Uses a clear question form that invites quantitative inquiry.

Weaknesses:
5

Specify two named variables with units (e.g., force F in newtons and acceleration a in m/s^2). For example: "How does force F (N) affect acceleration a (m/s^2)…"

How to Evaluate Your Research Question

Simply choose your subject and enter your research question. Our evaluator will then analyze your question against the IB requirements and return a report with any issues or improvements you can make. Trained on thousands of IB RQs marked by official IB examiners, our evaluator is able to provide accurate and helpful feedback.

Frequently Asked Questions

Yes. Our Research Question Generator was trained on thousands of high-scoring IB exemplars, and the ideas it generates are designed to align with IB criteria so you can develop research questions that meet the standards.

Select your subject and category (IA or EE), optionally enter a few keywords or interests, then click Generate. The AI returns research question ideas tailored to your subject, which you can refine further with the tweak tools.

No. You can leave the keyword field blank for instant inspiration, or add a few words about your interests to get more targeted ideas.

Generated questions are starting points aligned with IB expectations. Similar research questions appear across cohorts—what matters is that your investigation or essay content is your own work.

The Research Question Evaluator was trained on thousands of research questions marked by IB-certified examiners. It evaluates your research question using the same IB criteria, helping you understand its strengths and areas for improvement.

A clear physical relationship between measurable quantities, grounded in theory, with a method that produces enough data for graphs and uncertainties.

Physical validity, school-lab feasibility, and whether the question supports linearisation/error analysis.

Try combining specific physical quantities (like period, intensity, resistance, or force) with an apparatus idea. “Projectile motion” alone is weaker than a defined dependency.
