Classification Objective: TSW explain why scientists organize things into living groups describe Carolus Linnaeus’ classification system name the eight levels of classification differentiate between genus and species LS 5a-c

Levels of Classification Who lives in Newport News? Who lives in _____ neighborhood? Who lives on ____ street? Who lives in _____ house? What’s happening to the number of students raising their hands with each question?

Why do scientists classify? Classification – Process of grouping things Biology – study of living organisms Scientist who studies Biology - biologists

Why do biologists classify organisms? Makes them easier to study them Taxonomy - Scientific study of how living things are classified Carolus Linnaeus - Wrote descriptions of organisms he observed Placed organisms in groups

How are items placed in a grocery store? Write 6 sections/departments that you can find in a grocery store (note page) 1. Meat Department 2. Produce Section 3. Breakfast Food Section 4. Dairy Section 5. Household Cleaning Section 6. Frozen Food Section 7. Magazine Section

Carolus Linnaeus - Wrote descriptions of organisms he observed Placed organisms in groups based on observable features

Linnaeus’ naming system - Binomial nomenclature (B.N.) B.N. - Naming system in which each organism is given a two-part name Bi – two Nomial – Name or terms

Linnaeus’ naming system - Genus (Good) - First part of an organism’s scientific name –Always capitalized Scientific names written in Latin Very similar, closely related organisms Members of different groups usually cannot breed with one another.

e.g. (genus Felis – small cats) House Cat, Bobcat, and Ocelot House Cat Bobcat Ocelot

Genus Felis On the opposite example page Draw a House Cat, Bobcat and Ocelot Label it Genus Felis – (small cats) Characteristics: Sharp, retractable claws, purring and stalk their prey House Cat Bobcat Ocelot

Genus Canis On an example page Draw a Wolf, Coyote, and Husky Label it Genus Canis – domestic and wild dogs) Characteristics: You write 3 similar characteristics Wolf Coyote Husky <> Wolf

Linnaeus’ naming system - Species (Spaghetti) - Second part of an organism’s scientific name –This name is not capitalized Group of similar organisms that can mate and produce fertile offspring Sets one species apart from another Together a genus and species name – Make up a scientific name Identify one kind of organism

Genus Ursus - bears On an example page Draw the 3 bears Label each bear American Black Bear - Ursus americanus, Brown (Grizzly) Bear - Ursus arctos Polar Bear - Ursus maritimus American Black Bear - Ursus americanus Brown (Grizzly) Bear - Ursus arctos Polar Bear – Ursus maritimus

Remember Genus – first part of scientific name species – second part of scientific name Genus name for American Black Bear - Ursus species name for American Black Bear - americanus Ursus americanus

Genus name for Brown (Grizzly) Bear - Ursus species name for Brown (Grizzly) Bear - arctos Ursus arctos

Genus name for Polar Bear - Ursus species name for Polar Bear - maritimus Ursus maritimus

Seven Levels of Classification - Kingdom Phylum Class Order Family Genus Species

Kingdom - Broadest classification level 6 Kingdoms

Common Traits Exercise Look at the Upside down wedding cake on page 187. What are the common characteristics in each level? Carefully look at the Kingdom level -, make a list of common characteristics? Single Cell or Multicellular ? Autotrophs or Heterotrophs Animals ? Multicellular, Heterotrophs Animals

Common Traits Exercise Now look at the Phylum level -, make a list of common characteristics? Multicellular, heterotrophs, vertebrate or invertebrate animals Multicellular, heterotrophs, vertebrate animals Work with your tablemate to find common characteristics for the Class -, Order -, Family-, and Genus levels -

Class – multicellular, heterotrophs, vertibrate, animals with wings, feather, beaks, and claws (birds) Order - multicellular, heterotrophs, vertibrate, animals with wings with wings, feather, beaks, and claws (birds), plus, similar body shape

Family - multicellular, heterotrophs, vertibrates, animals with wings with wings, feather, beaks, and claws (birds), similar body shape, plus flat, round face Genus - multicellular, heterotrophs, vertibrates, animals with wings with wings, feather, beaks, and claws (birds), similar body shape, flat round face, plus forward facing eyes
