When is it useful to use a model?

• when something is too big to study

• when something is too far away to study

• when something is too small to study

• all of these

a model in motion, or a method used to study the characteristics of a system

• data

• accuracy

• simulation

a wave pool at the water park is an example of

• mathematical model

• conceptual model

• precision

• simulation

a quantitative description that includes a number and a unit

• observation

• model

• measurement

a description of how close a measurement is to the true value

• accuracy

• precision

• data

• model

A model that shows a relationship between numbers

• physical model

• mathematical model

• observation

a flow chart or diagram are good examples of

• mathematical model

• conceptual model

• physical model

Getting the same measurement over and over and over again

• accuracy

• precision

virtual reality is an example of

• physical model

• simulation

facts, figures, and measurements all together are called

• models

• precision

• data
