LS4.A: Evidence of Common Ancestry and Diversity

 

In this video Paul Andersen describes several types of evidence for common ancestry.  This evidence is contained in the fossils, embryos and molecules of living organisms.  Even though life on our planet is incredibly diverse there are common threads that run through everything.  This idea was most elegantly put forward by Charles Darwin before much of this evidence was gathered.  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.

SEP8: Obtaining, Evaluating and Communicating Information

 

Scientists and Engineers spend over half of their working day reading, evaluating and producing text.  Therefore it is important that we produce students that have a high level of scientific literacy.  Students normally struggle with scientific reading due to the high level of jargon and multiple modes of presentation (i.e. graphs, images, data).  We can help our students become more scientifically literate by having them consume and produce scientific text from K to 12.  Several strategies for teaching this progression (e.g. adapted primary literature and mini-posters) are included.
