Tips for using Science World in the classroom.

Melinda Mills, this teacher's edition's contributor, suggests: Once students have read this issue of Science World, extend their learning by introducing the term "scat" and its definition. Explain that scat, like animal tracks, provides useful information to scientists who are attempting to identify the animal that made it. Show the class images of scat, making sure to include examples from carnivores, omnivores, and herbivores. Scat photos can be printed out from numerous Web sites. One of my favorites is: www.bear-tracker.com/animalscat.html. Then, have students use the photos create their own dichotomous key for identifying the animals.
