A scientist who proposes a hypothesis that is eventually disproven is never allowed to be a scientist again. B. A scientist who disagrees with current theory is never allowed to be a scientist again. C. A scientist who makes a mistake is never allowed to be a scientist again. D. A scientist who lies in a scientific publication will suffer professional excommunication.

Briefly, what is science? A. Science describes the order in nature and the causes of that order. B. Science is a way of knowing about the world and making sense of it. C. Science creates testable laws and theories. D. All of the above.

D. All of the above.

Listed following are a series of statements that each make a claim. Classify these as either testable by accepted methods of science or non-testable by accepted methods of science. Be sure to note that this question does not ask whether a statement would pass or fail a test; it only asks whether it is testable in principle.

Testable by science. - Earth orbits the Sun every 365.25 days. - Mars once had liquid water on its surface. - There will be a solar eclipse next Tuesday at 11am. - People born under the sign of Sagittarius are twice as likely to be teachers as anyone else. - Bacteria acquire resistance to antibiotics through changes in their DNA. Not testable by science. - Vince Young is the greatest quarterback of all time. - Hurricane Katrina was an act of God.
