The Six Steps
The number of steps varies from one description to another, mainly when data and analysis are separated into separate step, but this is a fairly standard list of six scientific method steps, which you are expected to know for any science class:
Purpose/QuestionAsk a question.
Research
Conduct background research. Write down your sources so you can cite your references. In the modern era, a lot of your research may be conducted online. Scroll to the bottom of articles to check the references. Even if you can't access the full text of a published article, you can usually view the abstract to see the summary of other experiments. Interview experts on a topic. The more you know about a subject, the easier it will be to conduct your investigation.
Hypothesis
Propose a hypothesis. This is a sort of educated guess about what you expect. It is a statement used to predict the outcome of an experiment. Usually, a hypothesis is written in terms of cause and effect. Alternatively, it may describe the relationship between two phenomena. One type of hypothesis is the null hypothesis or the no-difference hypothesis. This is an easy type of hypothesis to test because it assumes changing a variable will have no effect on the outcome. In reality, you probably expect a change, but rejecting a hypothesis may be more useful than accepting one.
Experiment
Design and perform an experiment to test your hypothesis. An experiment has an independent and dependent variable. You change or control the independent variable and record the effect it has on the dependent variable. It's important to change only one variable for an experiment rather than try to combine the effects of variables in an experiment. For example, if you want to test the effects of light intensity and fertilizer concentration on plant growth rate, you're really looking at two separate experiments.
Data/Analysis
Record observations and analyze what the data means. Often, you'll prepare a table or graph of the data. Don't throw out data points you think are bad or that don't support your predictions. Some of the most incredible discoveries in science were made because the data looked wrong! Once you have the data, you may need to perform a mathematical analysis to support or refute your hypothesis.
Conclusion
Conclude whether to accept or reject your hypothesis. There is no right or wrong outcome to an experiment, so either result is fine. Note accepting a hypothesis does not necessarily mean it's correct! Sometimes repeating an experiment may give a different result. In other cases, a hypothesis may predict an outcome, yet you might draw an incorrect conclusion. Communicate your results. The results may be compiled into a lab report or formally submitted as a paper. Whether you accept or reject the hypothesis, you likely learned something about the subject and may wish to revise the original hypothesis or form a new one for a future experiment.

Scientific method
The Scientific method is a process with the help of which scientists try to verify, or construct investigate, an accurate and reliable version of any natural phenomena.
The six steps of the scientific method include:
1) asking a question about something we observe,
2) doing background research to learn what is already known about the topic,
3) constructing a hypothesis
,4) experimenting to test the hypothesis, 5) analyzing the data from the experiment and drawing conclusions, and
1.Observation and formulation of a question:
This is the first step of a scientific method. An observation has to be made into any observable phenomena or aspect of the universe and a question is to be asked pertaining to that aspect.
2.Data Collection and Hypothesis:
The next step involved in the scientific method is to collect all related data and formulate a hypothesis according to the observation.
3.Testing the hypothesis:
After the hypothesis is made, it is to be tested scientifically. So comes experiments. The aim of these experiments is to determine whether the hypothesis agrees with or contradicts the observations
4. Analysis and Conclusion:
In this step, the use of proper mathematical and other scientific procedures to determine the results of the experiment. Based on the analysis, the action can be determined future course .
Scientific Method Examples
The bean plant can grow anywhere if the scientific methods are used. Executing the hypothesis and collecting the data: Four bean plants are planted in identical pots using the same soil.
