- Give careful thought to experimental design. Once you have a feasible project idea, write a research plan. This plan should explain how you will do your experiments and exactly what it will involve.
- Decide what data you need to meet in your research objective and how you will collect it.
- Be sure to consider possible hazards in your experimental approach and decide how you can conduct your research safely.
- In order to obtain valid experimental results, consider the following items when designing the experiment:
- Make sure the quantity and quality of data you collect provides a reasonable assurance that your research objectives will be met.
- Identify all significant variables that could affect your results.
- Include a control or comparison group in your experimental design.
- Also, remember to use metric measurements whenever possible.
