The scientific method is a process for experimentation that is used to explore observations and answer questions.
Scientists use the scientific method to search for cause and effect relationships in nature. In other words, they design an
experiment so that changes to one item cause something else to vary in a predictable way.
And, in order for the scientific method to answer the question it must be about something that 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 insure that you
don't repeat mistakes from the past.
Construct a Hypothesis: A hypothesis is an educated guess about how things work:
"If _____[I do this] _____, then _____[this]_____ will happen."
You must state your hypothesis in a way that you can easily measure, and of course, your hypothesis should be constructed
in a way to help you answer your original question.
Test Your Hypothesis by Doing an Experiment: Your experiment tests whether your hypothesis is true or false. It is
important for your experiment to be a fair test. You conduct a fair test by making sure that you change only one factor at a
time while keeping all other conditions the same.
You should also repeat your experiments several times to make sure that the first results weren't just an accident.
Analyze Your Data and Draw a Conclusion: Once your experiment is complete, you collect your measurements and analyze
them to see if your hypothesis is true or false.
Scientists often find that their hypothesis was false, and in such cases they will construct a new hypothesis starting the
entire process of the scientific method over again. Even if they find that their hypothesis was true, they may want to test it
again in a new way.
Communicate Your Results: To complete your science fair project you will communicate your results to others in a final
report and/or a display board. Professional scientists do almost exactly the same thing by publishing their final report in a
scientific journal or by presenting their results on a poster at a scientific meeting.
Even though we show the scientific method as a series of steps, keep in mind that new information or the scientific method
that involves such backing up and repeating is called an iterative process.the scientific method that involves such backing
