Final answer:
A hypothesis is a testable and falsifiable proposed explanation that gains credibility through experimentation confirming predictions.
Explanation:
A hypothesis is a proposed explanation that can be tested through experimentation or observation. It must be testable and falsifiable, meaning it can be supported or refuted by experimental results.
Scientists perform experiments to either agree or contradict the predictions of a hypothesis. If results consistently support the hypothesis, it gains credibility as a useful description of nature.
Multiple hypotheses may be proposed before a prediction is made, and a hypothesis must be discarded if experimental results contradict it.
