Question

Models are used by scientists to analyze and understand a system.



How do models compare to what a scientist might be studying?



A.
Most models are created as exact copies of what the scientist is studying.


B.
Most models are larger than what the scientist may be studying.


C.
Most models simplify what the scientist is studying.


D.
Most models will be more complex than what the scientist is studying.

Answer 1

Models are usually "smaller" representations of what a scientist is studying. Think about for example a globe. A globe is a "model" of Earth. It is much smaller than Earth, however, it gives one an opportunity to explore it and understand things such as where all the countries in the world are and how much water exists compared to land.

Answer 2

A Model won't be an exact copy because that's not what a model is. Imagine someone trying to make an exact copy of Earth. It's just not possible.

Answer 3

im still kinda confused

Answer 5

thank you!!!

Answer 6

There's a difference between a human model, an experimental model, and mathematical model. From that perspective, I can understand how one can be easily confused. Each is defined differently and mean completely different things.

Answer 7

For example, Tyra Banks is a model, but that idea of a model has nothing to do with a mathematical model.

Answer 8

When trying to figure out the answer, just think of a globe in comparison to the Earth.

Answer 9

Is a globe an exact copy of Earth?
Is a globe larger than Earth?
Is a globe more complex than Earth?
