If we want to solve a problem then one approach is to make a model which captures important aspects of the circumstances of the problem.If the model is accurate and detailed enough then working with it should shed further light on the problem.Usually, a model means a simplified physical replica of something. For example, many childrensOCO toys are models of far more complexdevices. Models may be constructed at differing levels of closeness to the thing being modelled. For example, a basic toy car has four wheelsso that it can be pushed across a floor. A more complex model might have steerable wheels. An even more detailed model might have anelectric motor so that it does not need to be pushed. Finally, the model might have remote control so that its speed and direction can bechanged without direct contact."
