The Scientific Method involves the
following steps:
1.
Observation- You observe something in the material world, using your senses
or machines which are basically extensions of those senses.
2.
Question- You ask a question about what you observe.
3.
Hypothesis- You predict what you think the answer to your question might be
4.
Method - You figure out a way to test whether hypothesis is correct. The
outcome must be measureable. (quantifiable)
5.
Result- You do the experiment using the method you came up with and
record the results. You repeat the experiment to confirm your results.
6.
Conclusion- You state whether your prediction was confirmed or not and try
to explain your results.
A
conclusion will often lead to another question, which can lead to another
experiment, which can lead to another conclusion, and on and on. Science is
like doing a giant puzzle, with the handicap that you are missing an unknown
number of pieces. Each new scientific fact is a piece of the puzzle. Each new
piece can change the appearance of entire sections of the picture or fit where
one did not expect it to. When scientists have an answer to a question they
have asked, they share their results with other scientists in papers, magazine
articles, lectures, posters or displays at conventions. This way, new puzzle
pieces can be checked out, and the fit tested. You will present your results at
the science fair in the form of a display.
