Ask a Question: The scientific method starts when आप ask a सवाल about something that आप observe: How, What, When, Who, Which, Why, या Where?
And, in order for the scientific method to answer the सवाल it must be about something that आप can measure, preferably with a number.
Do Background Research: Rather than starting from scratch in putting together a plan for answering your question, आप want to be a savvy scientist using पुस्तकालय and Internet research to help आप find the best way to do things and insure that आप 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." आप must state your hypothesis in a way that आप can easily measure, and of course, your hypothesis should be constructed in a way to help आप answer your original question.
Test Your Hypothesis द्वारा Doing an Experiment: Your experiment tests whether your hypothesis is true या false. It is important for your experiment to be a fair test. आप conduct a fair test द्वारा making sure that आप change only one factor at a time while keeping all other conditions the same. आप 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, आप collect your measurements and analyze them to see if your hypothesis is true या 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 आप will communicate your results to others in a final रिपोर्ट and/or a display board. Professional scientists do almost exactly the same thing द्वारा publishing their final रिपोर्ट in a scientific journal या द्वारा presenting their results on a poster at a scientific meeting.
