Methods of Science(Scientific Facts, Hypotheses, Laws, and Theories)

In science, changing your mind when confronted with evidence that does not agree with your thinking is seen as

essential to scientific progress

Competent observers could all agree that the Leaning Tower of Pisa is actually leaning. This type of observation would best be called...

scientific fact

An orderly method for gaining, organizing, and applying new knowledge.

scientific method

A synthesis of a large body of information that encompasses well-tested hypotheses about certain aspects of the natural world.

theory

An explanation of why some part of the world behaves the way it does, and this explanation is based upon a large number of experiments developed over time.

theory

Science, art, and religion do not contradict one another because

All three have different domains

A Scientific theory is Select one: a. a phenomenon about which competent observers can agree. b. a synthesis of a large collection of data that includes well-tested guesses and has typically been developed over a long period of time. c. an educated guess that has yet to be proven by experiment. d. a guess that has been tested over and over and always found to be true.

B

When a scientific theory changes to take into account new data, the theory Select one: a. is now no longer useful to explain what is happening in nature. b. usually becomes stronger as it is now based upon more data. c. usually becomes weaker as it has now been shown to be incorrect. d. nonsense. Theory's do not change.

B

Which of the following is a scientific hypothesis? Select one: a. Friday is the best day of the week. b. Most apples have a higher sugar content than most bananas. c. The Earth started rotating due to powerful magic that can no longer be detected.

B

Which of the following is not a scientific hypothesis Select one: a. The combustion of fossil fuels releases carbon dioxide into the air. b. Nuclear power plants release fewer pollutants into the air than fossil fuels do. c. Fossil fuels like oil and coal should not be used because it is wrong to pollute the air. d. Solar energy panels release fewer pollutants than fossil fuels do.

C

Which of the following statements is a scientific hypothesis? Select one: a. An undetectable energy source is at the center of the Earth. b. Michael Jordan is clearly the greatest basketball player of all time. c. The universe is surrounded by a second universe, which cannot be detected. d. The back side of the moon has cities about the size of Chicago.

D

A scientific fact is something that is absolute and unchanging. True or False

False

A scientific theory is a law or hypothesis that is presumed true. True or False?

False

It is impossible to be both religious and scientific at the same time. True or False

False

Science is the "application of technology." True or False

False

The following is a scientific hypothesis. "The fossils of dinosaurs were placed where they were 10,000 years ago by "all-powerful" beings in such a way that any observation or experiment we do will give results that "look" like the fossils came from real dinosaurs that lived millions of years ago. True or False

False

How many experiments does it take to show that a hypothesis is False?

One

In science, an educated guess about the answer to a scientific question is called a hypothesis. True or False?

True

The difference between a hypothesis and a theory is that...

a hypothesis is a guess that has not yet been well tested, where as a theory is a synthesis of well-tested and refined guesses that has been developed over many years.

A scientific fact is

a synthesis of a collection of data that includes well-tested guesses.

A scientific hypothesis is

an educated guess that has yet to be proven by experiment

For a hypothesis to be considered a truly scientific hypothesis, there must be:

an experiment that can confirm or refute it

A ___________ is a scientists "educated guess"

hypothesis
