Answer:
Scientific method
Explanation:
scientific method describes the processes by which scientists gain knowledge about the world. It's characterized by six key elements: questions, hypotheses, experiments, observations, analyses, and conclusions. These elements are interrelated steps, so they don't always function in the same order.
The first step in the Scientific Method is to make objective observations. These observations are based on specific events that have already happened and can be verified by others as true or false.
Steps in scientific method
Step 1- Question. The "thing" that you want to know.
Step 2-Research. Conduct research.
Step 3-Hypothesis. Educated guess or prediction of the outcome experiment.
Step 4-Experiment. Test the hypothesis.
Step 5-Observations. Data you collect during the experiment.
Step 6-Results/Conclusion.
Step 7- Communicate.
