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.

SEP2: Developing and Using Models

Science and Engineering Practice 2: 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.
