2. My Planet Diary, pg. 14 What did Roxie Laybourne invent?
A new way to identify birds from their feathers
Why was her invention so important?
By identifying the birds that caused the crashes, engineers could take steps to prevent birds from running into planes and causing accidents

3. Why do biologists classify organisms?
Biologists use classification to organize organisms into groups so they’re easier to study.

4. Taxonomy -the scientific study of how organisms are classified
Taxonomy is useful because once you know how an organism is classified, you automatically know a lot about that organism.
Example: a crow is classified as a bird, so you know it has wings, feathers, a beak, hollow bones, etc…
Look at page 15, Figure 1

5. How might you classify: a sunflower, a robin, a lizard, a blue jay, and a tree?
-Sunflower and tree as plants -Robin, lizard and blue jay as animals -Robin and Blue jay as birds

6. Carolus Linnaeus Swedish botanist, 1730s
Placed organisms in groups based on observable features
Made a system for naming organisms (binomial nomenclature)

7. Binomial nomenclature
a unique, two-word scientific name
First word- genus
Second word- species

8. genus
A classification grouping that contains similar closely related organisms
Example:
-House cats and marbled cats both belong to the genus Felis
-They share characteristics such as sharp, retractable claws and behaviors such as hunting other animals

9. species
-A group of similar organisms that can mate with each other and produce offspring that can also mate and reproduce
-Often describes a feature of the organism, where it lives or what it looks like

10. Binomial nomenclature
Usually in Latin
- Written in italics
- Only the first letter of the first word (genus) is capitalized
- Example: Homo sapien

11. Binomial nomenclature
Makes it easy for scientists to communicate about an organism because everyone uses the same scientific name
Look at Page 17, Figure 3

12. 8 levels of classification (page 19)
Domain
Kingdom
Phylum
Class
Order
Family
Genus
Species Do Kids Pick Candy Over Fancy Green Salads

13. The more classification levels two organisms share, the more characteristics they have in common and the more closely related they are.

15. Tools for identifying organisms:
-Field guides – have descriptions and illustrations of organisms
-Taxonomic keys- a series of paired statements that describe the various physical characteristics of different organisms

16. Field Guides Using the Flowers field guide:
How many species of Monkeyflowers can be found in the U.S.? What family is it a part of?
Using the Field Guide to North American Reptiles & Amphibians:
What is the scientific name for the bullfrog?
Using the Field Guide to North American Birds:
What color eggs does the Cattle Egret lay?
