A law is a scientific truth and must explain or summarize a universal phenomenon. This law is based on facts and must be obeyed by any system imaginable, such as bodies, rivers or machines. Theories, on the other hand, are predictions about how something should happen based on an existing law. Theories are not exactly based on facts, as they do not represent an absolute truth.

A scientific model is the representation of a system (biological, physical, etc.) in small size. These models are used to represent very small or very large systems which are impossible to be visualized by human eyes. An example of this is a model that shows the structure of DNA that is a very small molecule, or a model that shows the solar system, which is a very large and very distant system.
