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: 04/19/23

Warm-up

Number your paper 1-7. Identify the type of symmetry on each

organism on the following slide.

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 site

11

Cladograms

• http://www.csupomona.edu/~jcclark/classes/bot125/resource/graphics/c/monocot_dicot.gif

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

Alien Taxonomy

• Today we will start by…– Cutting out the aliens so we are ready to

classify them tomorrow! • Keep in your group’s folder until next class.

– Begin thinking about how many Kingdom, Phylum, Genus and Species you will use

• What will characteristics differentiate each level of taxonomy?

14

If you need the papers at home..

• Alien Worksheet

• Alien Taxonomy Cards part 1

• Alien Taxonomy Cards part 2

15

Conclusion

• List at least 3 physical characteristics of the aliens that you will use to classify them tomorrow.
