In this video Paul Andersen defines adaptations and explains how organisms can become better adapted to their surroundings using the process of natural selection. Specific examples of adaptations, like coat color in rock pocket mice, as well as a K-12 teaching progression is included.
In this video Paul Andersen defines natural selection as differential reproductive success. He then explains how natural selection shapes organisms on our planet through variation and selection. 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.
