You didn't list your terms, but I can tell you what a hypothesis is:
A Hypothesis is an educated guess, generally used in science.
It's one of the first things you do in the scientific method.
For example: Before you start an experiment, there must be a REASON why you're starting the experiment. Thus, this means you must have a goal in mind. You can use that goal to form an educated guess.
For further Example: You have two plants. You plan on feeding plant 1 a different type of food than plant 2. You also plan on putting plant 1 in direct sunlight, and leaving plant 2 in darkness.
Your educated guess would probably be that Plant 1 will grow considerably healthier than plant 2.
~Hope this helps!
