so i had this experiment where i have to separate several substances from a mixture. one was separating iron filings from sand and the next question was:

why might this be important on an industrial scale?

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
