- 19. A hypothesis is an educated guess, or an untested explanation, that is based upon observations or know facts. For example, if an entomologist guesses that gray moths survive better on gray tree trunks, he or she has constructed a hypothesis. This hypothesis can be tested in one or more experiments or tests. If a hypothesis has been repeatedly tested and has not been disproved, it may become accepted as a theory. Examples include cell theory and atomic theory. A law describes what happens, but does not explain how it happens. One example is the law of gravity.
