30 POINTS Why would a scientist revise a model? (choose the best answer)
Group of answer choices

to cover up evidence from a previous experiment

to show off to other scientists

to add unnecessary details to the model

in order to better explain what is happening during a phenomenon

When modeling it is important to (pick two)
Group of answer choices

show beginning, middle and end if it fits the phenomenon

only use one color

make sure there is only drawings and nothing written

use zoom in bubbles to show the unobservable

Which of the following is NOT a limitation of a model
Group of answer choices

inaccurate colors

the type of material used to create the model

a messy model

shapes that are an approximation

First Question: in order to better explain what is happening during a phenomenon

Second Question: show beginning, middle and end if it fits the phenomenon; use zoom in bubbles to show the unobservable

Third Question: the type of material used to create the model

Explanation:

First Question: You would not revise a model to "cover up evidence," that's scientifically immoral and should not be done, and showing off to other scientists is not the point of revising something.

Second Question: You should use more than one color to differentiate different parts of the model, but don't overwhelm it with color. There should be some labels in the model, so some writing is necessary.

Third Question: Inaccurate color representation does not technically limit a model unless color scheme is important, so this could be an answer, but not likely. A messy model limits a model because it makes it hard to read. Approximating shapes is a limitation because it portrays an incorrect representation of what system the model is of. The type of material used to create the model is most likely the right answer.
