PS2.A: Forces and Motion

Disciplinary Core Idea PS2A: 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

Crosscutting Concept 1: 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.

SEP3: Planning and Carrying Out Investigations

Science and Engineering Practice 3: 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.
