PS2.A: Forces and Motion

Paul Andersen introduces forces, motion, and Newton's three laws in this video.  He begins by describing forces as pushes or pulls on objects that produce motion.  A lack of motion results from a balanced set of forces.  A teaching progression K-12 is also included.

CCC1: Patterns

Paul Andersen explains patterns and describes why pattern recognition is an important skill in science and engineering.  He begins by discussing patterns in nature, including snowflakes, flower petals, seasons and nucleotides in DNA.  He then illustrates the importance of classification in describing and eventually understanding patterns.  He gives a progression instruction in the science classroom from grade K to 12.  A secret pattern is hidden within the video.

SEP3: Planning and Carrying Out Investigations

Paul Andersen explains how investigations are used by scientists to answer questions and by engineers to test designs.  He delineates be investigative and observational science.  He demonstrates the formation of a good question the design of an effective investigation.
