CCC4: Systems and System Models

Crosscutting Concept 4: Systems and System Models 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.

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.

SEP7: Engaging in Argument from Evidence

Science and Engineering Practice 7: Engaging in Argument from Evidence Paul Andersen explains the importance of argumentation in improving both understanding and design. This video begins with a discussion of the heliocentric and geocentric model of the Universe that eventually lead to the Copernican Revolution. It highlights the importance of both informal and formal arguments.
