Comparative Anatomy NGSS MS-LS4-2 and MS-LS4-3

Comparative Anatomy 

     The comparative study of the body structures of different species of animals in order to understand the adaptive changes they have undergone in the course of evolution from common ancestors.
      Charles Darwin made extensive use of comparative anatomy in advancing his theory, and it in turn revolutionized the field by explaining the structural differences between species as arising out of their evolutionary descent by natural selection from a common ancestor.
     Since Darwin’s time, the study of comparative anatomy has centered largely on body structures that are homologous—i.e., ones in different species that have the same evolutionary origin regardless of their present-day function. 

Comparative Anatomy and Embryological Development for Middle School

      An online unit for NGSS MS-LS4-2 and MS-LS4-3. Students will learn about evidence such as homologous structures, analogous structures, and embryological similarities. Students will see evidence that species have changed over time. This unit begins with phenomena. This unit is completely online and digital with interactive slides. You may also be interested in the Analyzing the Fossil Record unit.

Distance Learning Science Unit: Evidence for Evolution: NGSS MS-LS4-2 and MS-LS4-3. Students will learn about homologous structures, analogous structures, and embryology as evidence for common ancestry. This is a completely online unit in Google Slides and Google Forms. These slides are interactive.  Students will read information or watch a video and they will respond right on the slide by typing on the slide or completing interactive drag and drop activities. This unit is self-directed and perfect for distance learning or Google Classroom.  It ends with a unit quiz in an editable Google Form.

This resource is aligned with
NGSS MS-LS4-2. Apply scientific ideas to construct an explanation for the anatomical similarities and differences among modern organisms and between modern and fossil organisms to infer evolutionary relationships. [Clarification Statement: Emphasis is on explanations of the evolutionary relationships among organisms in terms of similarity or differences of the gross appearance of anatomical
And
NGSS MS-LS4-3 Analyze displays of pictorial data to compare patterns of similarities in the embryological development across multiple species to identify relationships not evident in the fully formed anatomy. [Clarification Statement: Emphasis is on inferring general patterns of relatedness among embryos of different organisms by comparing the macroscopic appearance of diagrams or pictures.] [Assessment Boundary: Assessment of comparisons is limited to the gross appearance of anatomical structures in embryological development.]
Utah SEEd Standard 7.5.3
Construct explanations that describe the patterns of body structure similarities and differences between modern organisms, and between ancient and modern organisms, to infer possible evolutionary relationships. (LS4.A)
and
Utah SEEd Standard 7.5.4
Analyze data to compare patterns in the embryological development across multiple species to identify similarities and differences not evident in the fully formed anatomy. (LS4.A)

I am so impressed with this unit which manages to be distance learning and hands-on at the same time.  Really well thought out and engaging activities that allow students to practice each of the eight Science and Engineering Practices.  Really no prep for me!

The elephant article was excellent but I also thought the lab on dissecting a flower was broken down so easily, even telling me where to get inexpensive flowers!  This resource helped me teach this challenging standard in an engaging way.  Worth every penny!

My students loved this unit. I was able to present different elements of it throughout the month. It is hard to find interesting non-fictional, age-appropriate text for my students that they will enjoy. This was a great unit that aligned well for my students who have very different goals within the same group.
