1 Acc Diversity of Life What is Taxonomy? Taxonomy

2 Maryland Science Content Standard Students will be able to provide examples and explain that organisms sorted into groups share similarities in external structures as well as similarities in internal anatomical structures and processes which can be used to infer the degree of relatedness among organisms

3 Objectives Students will be able to provide examples and explain that organisms sorted into groups share similarities in body structures and how they carry out life processes. Title:Taxonomy Date:5/20/2015

4 Warm-up  Number your paper 1-7.  Identify the type of symmetry on each organism on the following slide.

6 Today Students Will… Explore how organisms are classified according to shared characteristics. Explore how to show relationships among organisms on a cladogram. Explain how organisms are scientifically named Engage their thinking about classification by completing an alien taxonomy activity.

7 What is Taxonomy? Taxonomy is the scientific study of how living things are classified. How is taxonomy useful? –Once an organism is classified, you determine what the characteristics of the organism are based on other organisms found in the same classification

8 How do we know how organisms are related? What characteristics can organisms share? –We will complete the “Animal Limb” activity at the beginning of the site as an exploration for how scientists classify organisms Taxonomy Activity

9 Classification Organisms are classified according to history of the species. If organisms share a common ancestor they are related. Species with similar histories are more closely related.

10 What is a Cladogram? Use this site to learn about how cladograms are made and how they are used in taxonomy. –Cladogram siteCladogram site

11 Cladograms

12 Binomial Nomenclature An organism’s scientific name consists of its Genus and species names. Turn to page 18 in your “From Bacteria to Plants Book” and find the “What’s in a Name” Activity –Felis concolor (puma) –Felis marmorata (marbled cat) –Felis domesticus (house cat) What is the advantage of using scientific names?

13 Zoobooks You will create a book that showcases animals belonging to major classes of organisms You will compare animals belonging to different taxonomic groups You will establish characteristics associated with a taxonomic group

18 Zoobook Include –Cover and title page (including names of all group members) –A completed page of each animal on the list bound into each folder (using the templet)using the templet –Four compare and contrast pages (at the end)contrast pages

19 Conclusion What characteristics do the members of your order of animals have in common? If you needed to break your order into families, what characteristics would you base your classification on and why??
