B

Question 2

Compare the idea, physical, and computer models.

Revolt · Accepted Answer

An idea model represents a system with concepts, words, or diagrams. A physical model is a tangible three-dimensional representation. A computer model is a digital simulation that can use data to show, analyze, or predict how a system behaves.

Question 3

What are some possible uses for scientific models?

Revolt · Accepted Answer

Scientific models can be used to describe and explain systems, make predictions, test hypotheses, communicate ideas, and study systems that are too large, small, complex, dangerous, or slow to observe directly.

Question 4

Explain why all models have limitations.

Revolt · Accepted Answer

All models have limitations because they simplify real systems and cannot represent every detail, variable, or condition. Their accuracy is also limited by the assumptions and data used to create them.

Question 5

Scientific models _______.a.are based on a set of observationsb.are used to replace experimentsc.allow the study of existing systems onlyd.are rarely used

Revolt · Accepted Answer

A

Question 6

List possible limitations to scientific models.

Revolt · Accepted Answer

Possible limitations include oversimplifying a system, leaving out important variables, relying on incomplete or inaccurate data, and not applying to all situations or conditions.

Question 7

Which of the following types of models is most likely to be used to predict earthquakes?a.idea modelb.physical modelc.computer modeld.none of the above

Revolt · Accepted Answer

C

Question 8

A scientific model can be used to _______.a.replace study of the actual systemb.better understand systems and processesc.complicate ideasd.all of the above

Revolt · Accepted Answer

B

Question 9

Explain the purpose of scientific models.

Revolt · Accepted Answer

The purpose of scientific models is to represent and simplify systems or processes so scientists can better understand them, test ideas, explain observations, and make predictions.

Question 10
