This NOVA program includes many facts about how crocodiles live. But this program is just one of many sources from which you can obtain information about these complex creatures. In this activity, you will collect information from several different sources and then evaluate your findings.
Procedure First make a chart like the one below on a separate sheet of paper.
Next, fill in your group's assigned topic either the anatomy and physiology of crocodiles or their social behaviors. Research other sources to see whether they contain information that agrees or differs from the facts you collected from the NOVA program. Once you have completed your research, consider all of your facts, and choose which source or sources you most believe for each fact. List this source in the last column of your table and give your reasons for why you feel this source is most believable. Choose one of the following roles and explain why the reliability of sources might be important to you in your work.
