ESS1.B: Earth and the Solar System

In this video Paul Andersen explains the parts of the Solar System; including the planets, dwarf planets, moons and asteroids.  He explains how everything orbits around the Sun and how a proper understanding of this heliocentric model helps to explain planetary motions, eclipses, seasons, phases and even day and night.  A teaching progression K-12 is also included.

ESS1.A: The Universe and Its Stars

Paul Andersen describes our place on the Earth in the Solar System within the Milky Way Galaxy in the Universe.  The make-up and origins of the Universe are included along with stellar evolution.  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.

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.
