What is Science?

Scientific work is often inspired by

• testing a hypothesis

• creating experients

• careful observations

A scientist conducted an experiment to determine the effect on the color of fur of a Himalayan rabbit. The Himalayan rabbit typically has a white coat except for its colder nose, feet, tail and ears, which are black. The scientist shaved an area of hair on the back of each rabbit, then placed an ice pack over the shaved area on one rabbit (A). Why is rabbit B essential in this experiment?

• Rabbit B is the male rabbit

• Rabbit B is the control rabbit

• Rabbit B is the experiental rabbit.

• an absolute scientific certainty

• a highly tested, generally accepted principle

• a guess made with very little knowledge to support it

A controlled experiment allows the scientist to isolate and test

• a single variable

• several variables

• a mass of information

Logical interpretations based on prior knowledge or experience within the scientific community.

• inference

• quantitative data

• qualitative data

Scientific hypotheses are most often tested by the process of

• analyzing data

• communicating

• experimenting

"The plant in Container A has five offshoots" is an example of a _________ observation.

• hypothesis

• qualitative

• quantitative

Scientists publish the details of important experiments so that

• their work can be repeated

• their experimental procedures can be reviewed

• others can try to reproduce the results

A well-tested explanation that unifies a borad range of observations is a(an)

• controlled experiment

• inference

• theory

In science, a hypothesis is useful only if

• it is proven correct

• the explanation is already known

• it can be tested
