Classification

Read these instructions and complete all parts.

Part 1 Go to this website:

http://www.pbs.org/wgbh/nova/nature/classifying-life.html  If you right click and open in a new tab or new window, you can come back to this page by switching windows.  

Go through interactive (click on the launch interactive button) and go through the three types of organisms.  Read the descriptions and try to get it right.  DON’T JUST CLICK!  When you get to the end of each organism, record your score on the paper. 

 

Part 2 You will draw a cladogram:

One kind of family (phylogenic) tree is called a cladogram.  The cladogram shows the relationships of organisms as one kind of difference occurs to each and they branch off. 

This is a cladogram for mammals.  Today you will draw a diagram showing the relationships for one of the following animals: human, eagle, great white shark, octopus, king cobra, or bullfrog. You must include, at least, 4 ancestor organisms and indicate what the difference is that branches it off from the other.  You may use the internet to research relationships.  The site http://tolweb.org/tree/phylogeny.html  is an attempt to show the tree of life for all organisms.  This may be a useful resource.
