Natural Selection Webquest

1. BEFORE STARTING THE WEBQUEST, PLAY THE ANTIBIOTIC GAME.

2. THEN TRY THIS ACTIVITY ABOUT INTERPRETING FOSSIL FOOTPRINTS

3. THEN TRY THIS ACTIVITY ABOUT THE PROCESS OF FOSSILIZATION.

4. THEN TRY THIS ACTIVITY ABOUT HOW CAMOFLAGE HELPS PREDATOR AND PREY SURVIVE.

5. THEN TRY THIS ACTIVITY ABOUT PUTTING TOGETHER FOSSIL SKELETONS.

6. AND THIS ONE ABOUT THE PROCESS OF FOSSILIZATION.




NATURAL SELECTION WEBQUEST.
PART 1. ANTIBIOTIC RESISTANCE
1. WATCH: WHY DOES EVOLUTION MATTER NOW?
Go to Microbe Clock Interactive.
How do humans influence the evolution of microbes?


How does natural selection work to produce multi-drug-resistant tuberculosis?


Why is understanding evolution especially important today, now that people can travel easily?


EVOLUTION OF THE EYE
Watch the Evolution of the Eye video
Why were people resistant to the idea that the eye evolved through natural selection?

What evidence can you give to show that evolution did occur through natural selection? (For example, some animals alive today have simpler stages of the eye; Nilsson's work shows how the evolution could take place through small changes, etc.)


Why has the flatworm not evolved a more complex eye with a lens?




SEXUAL SELECTION:
Try the The Mating Game Web feature, and watch Sweaty T-shirts and Human Mate Choice video.


What role does sexual selection play in natural selection?



Why have male competition and female choice evolved as a selection means in many species? What role does partner selection play in genetic diversity?

SEXUAL SELECTION VS. NATURAL SELECTION:
TRY THE SEX AND THE SINGLE GUPPY http://www.pbs.org/wgbh/evolution/sex/guppy/
What hypotheses did you test?


What conclusions did you reach based on your simulation results?


How do sexual selection and natural selection interact in this guppy simulation? In nature?

Designasaurus

Your team will receive a dinosaur skeleton that has just been discovered. Use the skeleton to write a report in StarOffice Writer on this newly discovered dinosaur. Your report should include the following sections.
I. Dinosaur name. State the reason why your team chose this name for the new dinosaur.
II. Dinosaur model. Find a picture for what you think this dinosaur looked like when alive.
III. Size of dinosaur. Estimate how large (length and height) you think this dinosaur was.
IV. Probable habitat. State your reasons why you feel this dinosaur lived in such a habitat. Base your hypothesis at least partly on the fossils found.
V. Diet. What did your dinosaur eat? State your reasons why you feel this dinosaur had the diet you describe.
VI. Hunting/Grazing Methods. Did the dinosaur hunt or graze? State your reasons.
VII. Adaptations of the skeleton. List any adaptations you see on the skeleton and describe the probable usefulness of such adaptations for this dinosaur.
VIII. Socialization. Did the dinosaur live in groups or alone? State your reasons.
IX. Further information. Describe any other predictions you have for this dinosaur and how it lived.

FOSSILS WEBQUEST

THIS IS THE SITE YOU NEED TO USE FOR THE HOMEWORK:

http://ats.doit.wisc.edu/biology/ev/ns/ns.htm

IF YOU CHOOSE, YOU CAN INSTEAD TRY THESE...

1. Explore Some of the Interactives at the PAleontology Channel at Ology

2. Look at this interactive about fossilization.

3. Explore the BBC Prehistoric Life Site.

4. Sea Monsters Game

5. Fossil Jigsaw Game (May be blocked)

http://www.bbc.co.uk/nature/animals/mammals/challenges/flash/maker.shtml

6. BIG AL THE ALLOSAURUS GAME http://www.bbc.co.uk/cgi-perl/dinosaurs/bigalgame/bigal.pl?cxn_speed=F&BEGIN.x=19&BEGIN.y=22 1) What characteristics helped your organism survive? 2) What dangers did your organism face?
