1.2 Explain the difference between an hypothesis, theory and law in Science.
Evolution, the change of organisms from simple forms to more complex forms over long periods of geologic time, is called a theory.
But the word theory has a special meaning in Science, different from how we hear it used in detective stories and in the news.
Use the carousel to the right to develop "detective theories" for the scenarios.

A theory in science is different:
A scientific theory is an explanation of an aspect of the natural world that can be repeatedly tested and verified with the scientific method (using accepted methods of observation, measurement, and evaluation of results). Where possible, theories are tested under controlled conditions in an experiment.
A theory is not unchangeable. Theories change with new evidence.
A scientific law is a theory that proves to be true over many tests. This word is the reverse of how the word is used in the legal system. There a law is a legal requirement for people to obey. In Science, a law is something that describes a consistent relationship in nature, often mathematically; a law tells us what happens, but not necessarily why.
A scientific hypothesis is a testable prediction based on observations. It can be supported or rejected by experiments.
