universe
Steps of the Scientific Method - correct answer ✔-start with an observation or idea
-suggest a hypothesis
-make a prediction
-perform a test experiment, or additional observation
The process of making predictions and testing scientific models never ends, as there is always the
possibility that some future experiment or observation will show that a previously well-accepted model
doesn't actually work under all circumstances. However, if a hypothesis is backed up by a very large
body of evidence and has never failed a test, it may be elevated to the status of a theory. According to
the scientific method, choose all of the following statements that are correct. - correct answer ✔-All
theories have enough supporting evidence behind them that we can move forward under the
assumption that they are correct unless some future test proves that this is not the case.
-A theory has a higher probability of accurately modeling a natural phenomenon than a hypothesis does.
