LS1.A: Structure and Function

How do the structures of organisms enable life's functions?  Benchmarks for grades 2, 5, 8 and 12 are included.

CCC6: Structure and Function

Paul Andersen explains how the structure of objects are related to their function and vice versa.  He begins with a quick quiz on bicycle construction and ends with a progression of teaching for students grades K-12.  He also explains how the scale of an object will determine the function studied.

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.
