1. Question/Problem: What are you trying to figure out? This is the foundation of your experiment. It should be specific and testable.

2. Hypothesis: This is a testable prediction about what you think will happen based on your research and understanding. It's a possible answer to your question.

3. Experiment: This is the actual procedure you follow to test your hypothesis. It should be carefully designed with clear steps to ensure you can repeat the experiment and get reliable results.

4. Data: This is the information you gather during your experiment. It can be measurements, observations, or other recordings. Organize it neatly so you can analyze it.

5. Conclusion: This is your interpretation of the data. Does your data support or refute your hypothesis? Explain your reasoning and any further questions your experiment raises.

Remember, a simple experiment doesn't have to be complicated. Even a basic experiment that tests the effect of light on plant growth can demonstrate these fundamental components.
