The Hypothesis: "Hypothesis" means "what do
you expect to happen in your experiment?" Suppose your research question is,
"what happens to seeds if I change the temperatures they are kept at before
they are planted?"
The hypothesis might be "the higher the temperature
that seeds are kept at, the quicker I expect them to sprout." It's important to
word your hypothesis correctly. For example, don't say "higher temperatures are
better for seeds." "Better" cannot be measured. Decide on a hypothesis that can
be proved in a measurable way. For example, "higher temperatures will make the
seeds sprout faster."
It is perfectly fine for your experiment to
disprove your hypothesis. If something unexpected happens during your
experiment, the project doesn't need to be trashed. You just discovered
something new and showed that what we expect is not always what we get.
