1 Classifying Organisms What is a Panda? Scientists had difficulty determining the relationship of the Panda with other organisms.

2 What is a Panda? THE QUESTION

3 What is a Panda? THE QUESTION Raccoon Red Panda Panda Bear

4 What is a Panda? THE QUESTION

5 THE QUESTION What is a Panda?

6 Taxonomy Part 1 Classification

7 D 2 We are learning to investigate the principles of scientific classification Success Criteria: I can - draw biological diagrams of representative organisms from each of the kingdoms - classify organisms using dichotomous keys - create a dichotomous key to identify organisms D 3 We are learning to demonstrate an understanding of the diversity of living organisms Success Criteria: I can - use appropriate terminology related to biodiversity - explain the fundamental principles of taxonomy - concepts of taxonomic rank and relationship (eg., 7 genus, species, taxon )

8 How do we classify organisms? Kingdom is the top level in categorizing There are 7 levels in total:

9 Kingdom Phylum Class Order Family Genus Species

10 How do we classify organisms? Kingdom is the top level in categorizing There are 7 levels in total: Eg: housefly Eg: human Kingdom Animalia Animalia Phylum arthropod chordata Class insecta mammalia Order diptera primates Family muscidae hominidae Genus Musca Homo Species domestica sapiens

11 K P C O F G S King Philp cut open five green snakes

12 Binomial Nomenclature every living thing has its own name that includes genus & species examples: Name of the house fly: Name of a beaver: Musca domestica Castor canadensis These names tell us about the organism

13 Which of the following are most closely related?

14 Rob Ford Chimp Baboon Kingdom Animalia Animalia Animalia phylum chordata chordata chordata class mammalia mammalia mammalia order primates primates primates family hominidae hominidae Cercopithecidae genus Homo Pan apio species sapiens Troglodytes anubis

21 D 2 We are learning to investigate the principles of scientific classification Success Criteria: I can - draw biological diagrams of representative organisms from each of the kingdoms - classify organisms using dichotomous keys - create a dichotomous key to identify organisms D 3 We are learning to demonstrate an understanding of the diversity of living organisms Success Criteria: I can - use appropriate terminology related to biodiversity - explain the fundamental principles of taxonomy - concepts of taxonomic rank and relationship (eg., 21 genus, species, taxon )

22 Creating Dichotomous Keys s D 2 We are learning to investigate the principles of scientific classification Success Criteria: I can - create a dichotomous key to identify organisms - classify organisms using dichotomous keys

23 Let s make our own Dichotomous Key How should we start to group the following?:

24 Remember Only two choices per number Use clear characteristics (descriptive If you use size as a characteristic, you must reference something else (eg., length is 3X as long as width; less than 20 cm ) Do NOT only say long short wide big small 24

25 My Dichotomous Key for Beetles Create a key for the 8 beetles you are given. Be sure that the people on either side of you have a different group of beetles. When complete, test it out give a sample to someone to confirm that they can properly identify the beetle. How will you be assessed? I will randomly select two beetles to identify. If I am able to identify them perfect! Paperclip your beetles to your key when finished!!! 25
