Scientific models help scientists make predictions about complex systems. They are used to explain phenomena, and to communicate scientific knowledge. There are various ways to build them. Some models are tangible, while others use numbers and ideas. Models can help scientists understand and visualize the universe. One example is the planetary model of an atom, which depicts the atom as a nucleus with electrons orbiting it. Although this model is a simplified and oversimplified description of an actual atom, it is useful in helping scientists understand the atom.
