LS1.D: Information Processing

In this video Paul Andersen explains how information is processed in in animals.  He starts by describing the different forms of information and how they are received by receptors.  He explains how information is received by the brain and processed using different regions.  He finishes with a description of memories and emotions.
 

CCC4: 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.  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.

SEP2: Developing and Using Models

Paul Andersen explains the importance of modeling in science and engineering.  Models are used by scientists to explain phenomenon.  Unlike mental models, conceptual models can be shared by all scientists to improve our understanding of the Universe.  Engineers use models study systems and test designs.
