BYOD lesson. 9th Grade. Taxonomy

This is first lesson in row of evolutionary studies. Enjoy

Taxonomy

Learning outcomes

Content: to be able to explain classification system in biology.

Language: to be able to use specific vocabulary to explain taxonomy and classification in biology.

Exercise 1. Step one (individual work). Look at each fingerprint below. Criminologists use a system for classifying fingerprints to make it easier to compare. What categories would you divide them in to? What subcategories?

Step two (pair work). Discuss your answers with the partner.

Classification systems are used to organise information. In biology they are used to distinguish specific types of organisms.How scientists describe fingerprints:Loops: start and end on the same side, which is the same side as the opening of the loop.Arches: go from one side to the other.Whorls: roughly circular, ridge lines go all the way around.

Exercise 2. Step one (individual work). Answer true or false to the following statements. Use the picture to determine the answers.

1. ______ Dogs belong to the order Felidae.

2. ______ A fox belongs to the phylum Arthropoda.

3. ______ Snakes belong to the phylum Reptilia.

4. ______ Lions belong to the class mammalia

5. ______ All arthropods belong to the Class Insecta

6. ______ All rodents belong to the phylum chordata.

7. ______ All amphibians belong to the class reptilia.

8. _______ All primates are mammals.

9. _______ The class mammalia includes dogs, cats and rats.

10. ______ A lion belongs to the genus Felis.

11. ______ All mammals are primates.

12. ______ Insects and lobsters are arthropods.

In each set, circle the pair that is most closely related.

13. snakes & crocodiles | snakes & frogs 

14. rats & cats | cats & dogs

15. insects & lobsters | insects & birds

16. lions & tigers | lions & cougars

17. foxes & rats | foxes & dogs

18. cats & dogs | cats & lions

Step two (team work). Discuss your answers with the team.

Step three (individual work). List (use species name) all the animals pictured that belong in the Felidae family.

Exercise 3 (individual work). Essay. How would you explain classification of organisms to the person who had never heard about it before.
