A scientific hypothesis example, understanding and using the scientific method
On the next page, we'll discuss the ways that you can go about designing a science fair experiment idea.
An important thing to remember during this stage of the scientific method is that once you develop a hypothesis and a prediction, you shouldn't change it, even if the results of your experiment show that you were wrong. The alternative hypothesis may take several forms, depending on the hypothesis example of the hypothesized relation; in particular, it can be two-sided for example: If your original hypothesis didn't match up with the final results of your experiment, don't change the hypothesis.
In fact, some laws, such as the law of gravity, can also be theories when taken more generally. All swans are white. Several examples include the idea that living organisms develop from nonliving matter, which formed the basis of spontaneous generationa hypothesis that ultimately was disproved first inwith the experiments of Spondylolisthesis bladder control physician Francesco Rediand later inwith the experiments of French chemist and microbiologist Louis Pasteur ; the concept proposed in the late 19th century that microorganisms cause certain diseases now known as germ theory ; and the notion that oceanic crust forms along submarine mountain zones and spreads laterally away from them seafloor spreading hypothesis.
They are not falsifiable and they do not follow the scientific method. In framing a hypothesis, the investigator must not currently know the outcome of a test or that it remains reasonably under continuing investigation.
So you've got a scientist. When a conceptual framework is complex and incorporates causality or explanation it is generally referred to as a theory.
The experiment is the most important part of the scientific method. A simple but unlikely guess, if uncostly to test for falsity, may belong first in line for testing.
