In this video Paul Andersen explains the first step in the design process, defining and delimiting the engineering problem.  Design requires a clear definition of the problem and this is done by addressing both the constraints and criteria of each solution.  This will become increasingly important as future problems require complex solutions.  A K-12 teaching progression is also included.

CCC2: Cause and Effect

 

In this video Paul Andersen explains cause and effect its importance in science and engineering.  He starts by addressing the chain of interactions that must be present to show cause and effect.  He addresses the assumptions of universality and scale in determining cause and effect.  He finished the video with a progression of instruction from K-12.
