Compare High-Scoring vs. Flawed Biology RQs

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

1/10 Score
What are the effects of Biology on society?
Strengths:
2

The prompt is a single, coherent sentence that asks a broad question about biology's impact.

Weaknesses:
6

Define the independent variable with explicit values in brackets (e.g., "CRISPR gene editing in agriculture (CRISPR, conventional breeding)" becomes the explicit IV with two levels).

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

It is a complete sentence that starts with a query phrase indicating a relation to investigate.

Weaknesses:
6

Specify the independent variable with explicit values in brackets after the IV (e.g., light intensity (0, 100, 200 lux)).

10/10 Score
How does sucrose concentration (0%, 2%, 4%, 6%, 8% w/v) affect the cellular respiration rate of Saccharomyces cerevisiae, as measured by the volume of CO2 produced (mL min⁻¹) over a 30-minute fermentation period using a gas syringe collection system?
Strengths:
5

Clear identification of the independent variable with explicit concentration values and units.

Weaknesses:
0
10/10 Score
How does light wavelength (450 nm, 550 nm, 650 nm, 740 nm) affect the photosynthetic rate of Elodea canadensis, as measured by the change in dissolved oxygen concentration (mg L⁻¹ min⁻¹) over a 10-minute exposure using a calibrated dissolved oxygen probe?
Strengths:
5

Clear link between the IV and DV with named variables.

Weaknesses:
0

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.

Free users get a limited number of generations per week. Your limit resets weekly. Upgrade to Pro for higher limits and full access to Clastify AI tools.

Try combining a biological organism or system, a specific factor (like enzyme concentration, light intensity, or pH), and a clear measurement method. Avoid vague “effect of pollution on plants” without variables.

Not required in the question itself, but implying quantitative comparison helps. You can refine processing choices after generating the research question.

A measurable biological relationship with clear IV/DV, ethical school-lab feasibility, and enough replicates for meaningful processing.
