Verified step by step guidance

Begin by understanding the scientific method, which is a systematic approach used in scientific investigation to explore observations and answer questions.

Identify the initial step: Observation. This involves gathering data and noticing phenomena that prompt a question.

Next, form a Hypothesis. This is a tentative explanation or prediction that can be tested through experimentation.

Conduct an Experiment to test the hypothesis. This involves designing a procedure to collect data and observe outcomes.

Perform Data Analysis to interpret the results of the experiment. This step involves organizing and examining the data to determine if it supports or refutes the hypothesis.

Draw a Conclusion based on the data analysis. This step involves summarizing the findings and determining the validity of the hypothesis.

Finally, engage in Peer Review & Publish. This involves sharing the results with the scientific community for evaluation and validation, ensuring the research is credible and reliable.
