general assumptions of how systems work.

mathematical principles that can be proven true.

Atomic theory, which describes the atoms that make up matter, has been explored for centuries. Scientists in ancient Greece first proposed that matter was made of units called atoms. For many years, scientists thought atoms were solid and could not be divided. Then, in the nineteenth century, scientists began to discover the particles that make up atoms. Modern techniques have allowed scientists to split atoms into increasingly smaller particles. Which of the following statements about theories is supported by the history of the atomic theory?

Theories can change in response to new evidence.

If new evidence contradicts earlier theories, it is a result of an experimental error.

Experiments with modern equipment cannot be used to support earlier theories.

A theory is discarded when new evidence contradicts a part of the theory.

A scientist spends a month observing two prairie animals, prairie dogs and ferrets, in their natural habitat. Based on his observations, the scientist states that ferrets are more active than prairie dogs. Why is his statement NOT a scientific theory?

The statement is not widely accepted and supported by sufficient evidence.

It is an observation of something in nature.

Prairie dogs and ferrets are different species.

The scientist has not conducted enough trials to draw a valid conclusion.

Which of the following best describes a scientific law?

A hypothesis that has been proven true

An educated guess based on observations

A theory that has been widely accepted

What is the primary difference between a scientific theory and a scientific law?

A theory explains why phenomena occur, while a law describes what happens

A law explains why phenomena occur, while a theory describes what happens

Theories are based on mathematical equations, while laws are based on observations

Laws are subject to change, while theories are not

Which of the following is an example of a scientific theory?

They are only valid for a limited time

Which of the following statements is true about scientific theories and laws?
