✅ Important Points to Remember for IB Physics IA

1. Choose a Focused, Measurable Research Question

Ensure your question is clear, specific, and includes both independent and dependent variables.

Example: How does the length of a pendulum affect its period of oscillation?

2. Contextualize the Research Question

Explain the relevance of your question and connect it to background theory. Cite reliable sources.

3. Plan a Valid Methodology

Define all variables and describe your apparatus and procedure clearly. Ensure others could replicate your setup.

4. Ensure Reliability and Minimize Uncertainty

Repeat trials, control variables, and include uncertainties. Discuss sources of random and systematic error.

5. Analyze Data Thoroughly

Use graphs, tables, and mathematical models. Include error bars, line of best fit, and comment on trends and anomalies.

6. Use Clear and Proper Scientific Communication

Define all symbols and units. Label axes properly. Use significant figures and correct equation formatting (e.g., F = ma).

7. Draw a Justified Conclusion

Directly answer your research question. Support your conclusion with data and explain whether your hypothesis was correct.

8. Evaluate the Investigation

Reflect on strengths and limitations. Discuss how issues impacted results and suggest realistic improvements.

9. Cite Sources and Use Academic Honesty

Always cite your sources for theory, data, and images. Follow a consistent citation style (e.g., APA).

10. Keep Within the Word Limit

Aim for about 2,000 words. Be concise and avoid unnecessary repetition.
