Accepted Answer

A law is a summary of observed behavior, often described in mathematical terms, while a theory is a well-substantiated explanation of some aspect of the natural world that can incorporate laws, hypotheses, and facts.

Question 2

Which of the following is not a step in the scientific method?&#10;A) Make an observation.&#10;B) Formulate a hypothesis.&#10;C) Perform an experiment.&#10;D) Change results to agree with your hypothesis.&#10;E) Develop a theory (or model).

Accepted Answer

Changing results to agree with your hypothesis is not a valid step in the scientific method. In fact, it is considered scientific misconduct to alter results to fit a particular hypothesis. The scientific method involves making objective observations, forming a testable hypothesis, conducting experiments to gather data, and developing a theory or model based on the evidence.
