Learn about the history, philosophy, and elements of the scientific method, an empirical approach to acquiring knowledge. Explore how scientists formulate hypotheses, test them, and revise them based on observations and experiments.
- Ask a Question. The scientific method starts when you ask a question about something that you observe: How, What, When, Who, Which, Why, or Where? For a science fair project some teachers require that the question be something you can measure, preferably with a number.
- Do Background Research. Rather than starting from scratch in putting together a plan for answering your question, you want to be a savvy scientist using library and Internet research to help you find the best way to do things and ensure that you don't repeat mistakes from the past.
- Construct a Hypothesis. A hypothesis is an educated guess about how things work. It is an attempt to answer your question with an explanation that can be tested.
- Test Your Hypothesis by Doing an Experiment. Your experiment tests whether your prediction is accurate and thus your hypothesis is supported or not. It is important for your experiment to be a fair test.

The first step of the scientific method involves making an observation about something that interests you. Taking an interest in your scientific discovery is important, for example, if you are doing a science project, because you will want to work on something that holds your attention. Your observation can be of anything from plant movement to ani...
Once you have made your observation, you must formulate a question about what you observed. Your question should summarize what it is you are trying to discover or accomplish in your experiment. When stating your question, be as specific as possible. For example, if you are doing a project on plants, you may want to know how plants interact with m...
The hypothesis is a key component of the scientific process. A hypothesis is an idea that is suggested as an explanation for a natural event, a particular experience, or a specific condition that can be tested through definable experimentation. It states the purpose of your experiment, the variables used, and the predicted outcome of your experimen...
Once you have developed a hypothesis, you must design and conduct an experiment that will test it. You should develop a procedure that states clearly how you plan to conduct your experiment. It is important you include and identify a controlled variable or dependent variable in your procedure. Controls allow us to test a single variable in an exper...
The results are where you report what happened in the experiment. That includes detailing all observationsand data made during your experiment. Most people find it easier to visualize the data by charting or graphing the information.
Developing a conclusion is the final step of the scientific method. This is where you analyze the results from the experiment and reach a determination about the hypothesis. Did the experiment support or reject your hypothesis? If your hypothesis was supported, great. If not, repeat the experiment or think of ways to improve your procedure.
Learn the six steps of the scientific method, a process that scientists use to answer questions about the natural world. See examples of how to formulate hypotheses, design experiments, and draw conclusions.
