What are the benefits of using models in science?

When students are engaged in scientific modeling, they are able to notice patterns and develop and revise representations that become useful models to predict and explain–making their own scientific knowledge stronger, helping them to think critically, and helping them know more about the nature of science.

What are scientific models?

A scientific model is a physical and/or mathematical and/or conceptual representation of a system of ideas, events or processes. Scientists seek to identify and understand patterns in our world by drawing on their scientific knowledge to offer explanations that enable the patterns to be predicted.
