Scientific method example: Failure to toast 1. Make an observation.. Let's suppose that you get two slices of bread, put them into the toaster, and press the button. 2. Ask a question.. Why didn't my bread get toasted? 3. Propose a hypothesis.. A hypothesis is a potential answer to the question, ...

scientific method, mathematical and experimental technique employed in the sciences. More specifically, it is the technique used in the construction and testing of a scientific hypothesis. The process of observing, asking questions, and seeking answers through tests and experiments is not unique to any one field of science.

- 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. This is very important if you are doing a science projectbecause you want your project to be focused on something that will hold your attention. Your observation can be on anything from plant movement to animal behavior, as long as it is somet...
Once you've made your observation, you must formulate a question about what you have observed. Your question should tell what it is that you are trying to discover or accomplish in your experiment. When stating your question you should be as specific as possible. For example, if you are doing a project on plants, you may want to know how plants in...
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've developed a hypothesis, you must design and conduct an experiment that will test it. You should develop a procedure that states very clearly how you plan to conduct your experiment. It is important that you include and identify a controlled variable or dependent variable in your procedure. Controls allow us to test a single variable in ...
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.
The final step of the scientific method is developing a conclusion. This is where all of the results from the experiment are analyzed and a determination is reached 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 proce...
