Modelling is an abstraction of reality or a representation of a real object or situation. A model presents a simplified version of something. In other words, modelling is used when creating an object to be used as an example for something typically more complex. An example of modelling can be seen as constructing a small baking soda volcano model of Mt. Vesuvius for a science fair. The baking soda volcano represents the more complex object which is Mt. Vesuvius in this case.
