Question

People use models to represent many things. Sometimes we use models to represent large things like ships, cars, or buildings. We do this because we cannot bring those items into our homes or offices.

Sometimes we use models to represent small things, like an atom or a virus. We use models, in these cases, to help us visualize things too small to see with our own eyes.
