What is a hypothesis?

• An educated guess

• A hypothesis is a question on what you think will happen.

• A testable explanation

• A prediction that you can test using research

How is a theory different from a hypothesis?

• A theory has a large amount of testing

• A theory has a large amount of supporting evidence

• A theory has been proven

• A hypothesis has much more evidence than a theory: "It's just a theory!"

• A hypothesis explains observations. A theory describes them.

Which of these most accurately describes a law?

• A theory with a large amount of supporting evidence--it can no longer be refuted

• A description of observations

• An explanation of observations.

• A hypothesis with a large amount of supporting evidence form a large amount of testing.

• None of these. I would have left it blank, but I did not want to lose double points.
