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 CatHouse CatBobcat

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
