As the title suggests, this is a scaled representation of an existing invention. You are asked to make a WORKING model that simulates the operation of, and the scientific principles behind, an existing technology. You should choose a model which clearly illustrates a scientific principle. When you think about it, it is easy to understand the importance of models in science.
