A model is simply a copy of an original object. Usually, a model is smaller (but yet proportional) to the original object. There are many distant things that are too large to move around, such as landforms. Small models of such objects allow the majority to see what something is like. Other things, like a bird’s lungs, are hard to get to; you’d have to kill the bird to see its lungs. Models of such things allow us to see something that we probably wouldn’t see otherwise. Then there are things, like a plant cell, that are too small for us to see. Large models of such objects allow us to see them without looking through a microscope. All in all, models make it easier to see things.
