CCC4: Systems and System Models

Concept 4.jpg

In this video Paul Andersen explains how systems can be used to understand phenomenon in science and create better designs in engineering.  He starts by defining the characteristics of a system and describes how system models can be used to better understand the world.  For example a system model of the water cycle can show the cycling of matter on the surface of the Earth.  He ends with a progression of instruction for a K-12 science classroom.
