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.
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.
SEP4: Analyzing and Interpreting Data
Paul Andersen explains how scientists analyze and interpret data. Data can be organized in a table and displayed using a graph. Students should learn how to present and evaluate data.
