Go to the link on the Nathan Hale Biology Webpage: (www.sites.google.com/site/halebiology/ ) OR type in the following web address: http://www.indiana.edu/~ensiweb/lessons/whalekiosk.html 2. Follow the directions below, and answer each question in your logbook. Note: You may need to download a FLASH player…just click on the link and follow directions to do this.

Directions A. Click on Go to Whale site. B. Watch the introduction. C. Then click Enter. D. The first section is on Comparative Anatomy. You will compare the body parts of different types of animals. Click the turquoise screen to continue. E. Click Start. Question 1: In your logbook, describe the animation on the “From Land to Water” animation…what does it look like? (Note: Turquoise text indicates a link YOU SHOULD CLICK ON. Use the arrow buttons to go back or forward.)

Question 2: What is a cetacean? Describe using at least 4 distinguishing characteristics.

Directions F. Watch the instructions/how-to, by clicking on the next arrows. G. When you get to the whale, click on the different words to compare. Question 3: Draw the data table.

Question 4: Which animal was the whale more closely related to based on anatomy?

Question 5: How do you think scientists use this technique to categorize organisms?

Question 6: Explain what a cladogram is, and draw the cladogram.

H. Examine the comparison of teeth. Question 7: What type of organism is a Whale most closely related to based on its teeth? Describe this type of animal, and give 2 examples.

I.

Examine the comparison of ankle bones.
