How do you turn a research idea into a complete project?
Once you choose a topic, narrow it to one research question that can be answered with evidence. Then follow these steps:
1. Review existing research. Read reliable sources and note what researchers already know about the topic.
2. Choose your method. Decide whether to run an experiment, analyze public data, make observations, use a simulation, or review published studies.
3. Check feasibility. Identify the time, tools, data, and supervision you need before starting.
4. Record your method and results. Keep notes on your decisions, observations, and limitations so you can explain how you reached your conclusions.
