2. Do Now: Quiz yourself (do not use your notes)
1. What are the 8 levels of classification in order?
2. What are the 3 Domains?
3. What are the 4 Kingdoms of Eukarya?

3. The Nature of Science Subject to change
Discoveries usually not on purpose
We learn more about everything daily
A lot more left to discover: species, space, why things are the way they are.
Gregor Mendel- failed science but became the father of genetics!
Requires creativity- think outside the box!

5. Species: A group of similar individuals that can breed and produce fertile offspring.
mule
A mule is the offspring of a male donkey and a female horse.[1] Horses and donkeys are different species, with different numbers of chromosomes. A mule is easier to obtain than a hinny (the offspring of a male horse and a female donkey). All male mules and most female mules are infertile.

8. Symmetry
A PowerPoint Presentation created by Ms. Rollins using the collection of web pages created by the Adrian Bruce and his students
       

9. Bilateral Symmetry
Shape has bilateral symmetry (line symmetry) when one half of it is the mirror image of the other half.
Symmetry exists all around us and many see it as being a thing of beauty.
        How would you define the term 'line symmetry'?         Why might some people see line symmetry as a thing of beauty?

10. Is a butterfly symmetrical?

11. Animals that have Bilateral Symmetry
Use pictures that you take or that are public domain to avoid copyright issues

12. At the beach … there are a variety of shells with Bilateral Symmetry.

13. Which of the following has Radial Symmetry (Rotational Symmetry)?

14. Under the sea … there are also many symmetrical objects such as these crabs and this starfish.
This type of symmetry is also called reflectional symmetry as the two parts reflect/match along each side of a dividing line ( or axis ).

15. Oysters have what type of Symmetry?

16. To start your exploration, use the green Building Your Life Science Vocabulary books to take each of these words apart :
Bilateral Symmetry
Radial Symmetry
Asymmetrical Symmetry

17. Then, use your textbook, pages 315 – 317, and a dictionary to create a working definition (7 words or less).

18. Next step: Apply the new information
Work with your groups to analyze the specimens for symmetry
Report your findings in the class spreadsheet
The same specimens will be examined for characteristics that identify that organism with a specific classification level and scientific name later

19. Finally, evaluate what type of symmetry this rare crab has based on your working definitions of bilateral, radial, and asymmetrical symmetry.
