the nature of science

Homeostasis means

Keeping things the same

Scientific hypotheses are most often tested by the process of

Experimenting

A hypothesis is

A testable possible explanation of an observation

A hypothesis that does not explain an observation

Is rejected

Scientists usually design experiments

With a good idea of the expected experimental results

A scientific theory

May be revised as new evidence is presented

observation : hypothesis ::

Hypothesis : experiment

Which components of a scientific investigation benefit from communication?

All of the above

Correct order of the scientific method

Observations → hypothesis → predictions → controlled testing → theory → verification

Which is NOT good laboratory practice?

Working alone in the lab

Experiments and investigations must be

Repeatable

A variable that stays the same is a

Control (constant)

Science cannot answer questions about

Politics

To evaluate observations, you must use

Critical thinking

To infer means to

Draw a conclusion based on observation

An educated guess that can be tested is a

Hypothesis

Stating the expected result before testing is called

Prediction

Important science skills

Observing, measuring, analyzing, inferring (examples vary)

Important lab safety rules

Follow instructions, wear goggles, no eating or drinking, report accidents

Difference between observation and inference

Observation is what you see; inference is a conclusion based on what you see
