2. Bilateral Symmetry Shape has bilateral symmetry (line symmetry) when one half of it is the mirror image of the other half. 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. Symmetry exists all around us and many see it as being a thing of beauty.

3. Human Symmetry The 'Proportions of Man' is a famous work of art by Leonardo da Vinci that shows the symmetry of the human form.

4. Is a butterfly symmetrical?

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

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

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

8. Under the sea … there are also many symmetrical objects such as these crabs and this starfish.

9. Oysters have what type of Symmetry?

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

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

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

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