In this video Paul Andersen explains how natural disasters (like earthquakes, tsunamis, volcanoes and flooding) have affected and will continue to affect humans on the planet. Many of the natural hazards (like volcanoes and storms) can be studies directly and some (like earthquakes) can be predicted. Natural hazards will never go away but the damage can be limited. A K-12 teaching progression 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.
