I answered for #1) A hypothesis is a tentative, testable answer to a scientific question. ... Sometimes people refer to the tentative answer as "an educated guess." Keep in mind, though, that the hypothesis also has to be testable since the next step is to do an experiment to determine whether or not the hypothesis is right!
