Question

What are four good reasons to use a physical model rather than the real object it represents?

A.
The real object is too small to see with ordinary equipment.

B.
The real object is too common to be of interest to scientists.

C.
The real object is too dangerous for humans to handle.

D.
The real object is too expensive to replace if it breaks.

E.
The real object is too large to fit in a laboratory.

Answer 1

A, C, D, and E are all valid options.

often times, when physical models are used instead of actual models, it's because of the actual object's size or composition. that's why we have globes instead of actual models of the earth! they'd simply be too big to keep in a classroom :)

i hope i helped! good luck.
