A hypotheses is a highly educated guess as to what will happen in an experiment. You dont know the outcome until the experiment is finished under controlled circumstances.
A law is something that has been tried over and over and has been proven to be true without any doubt. Like the law of gravity. You cant disprove its existence.
A theory is just that...a guess into whether something is legitiment. You make a theory on experiments and the outcome of them. You may not have the answer but based on the experiments and their suggested outcome u form a theory about how something happened. It kind of a partial answer but not the full scientific answer
