In this video Paul Andersen describes both weather and climate. Weather is the day-to-day conditions on the Earth's surface, including temperature, wind, humidity, air pressure, and precipitation. Climate are the long term conditions on the Earth's surface. Both climate and weather are determined by sunlight, water, landforms and life forms. A K-12 teaching progression is also included.
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.
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.
