The topic of this video module is how to classify animals based on how closely related they are. The main learning objective is that students will learn how to make phylogenetic trees based on both physical characteristics and on DNA sequence. Students will also learn why the objective and quantitative nature of DNA sequencing is preferable when it come to classifying animals based on how closely related they are. Knowledge prerequisites to this lesson include that students have some understanding of what DNA is and that they have a familiarity with the base-pairing rules and with writing a DNA sequence.

This resource focuses on the difference of using physical characteristics (qualitative) to DNA sequence (quantitative) to create phylogenetic trees. The resource also explains the purpose of phylogenetic trees. The video is a little long and dry, but is interactive if the accessory handouts are ready for students. Students practice filling in phylogenetic trees based on physical characteristics and DNA sequences. This resource could be used with the entire class or individual students that require enrichment activities. Video and handouts are downloadable. HCPSIII- SC.BS.4.6 & SC.BS.5.3
