This second grade teaching unit centers on endangered animal species around the world. Questions addressed are: What is an endangered species? Why do animals become extinct? How do I feel about the problem? and What can I do? Students study the definition of endangered species and investigate whether it is a natural process. They explore topics such as the disappearance of homes, polluted habitats, over-hunting, and the sale or exploitation of animals. Unit skill goals focus on using the library to study a specific animal, and learning to use a map as a reference to locate endangered species. Attitude goals deal with helping students: (1) realize how personal attitudes and values have an impact upon potential solutions to the problem, and (2) learn that the students are not powerless and can make a difference. Behavioral objectives are keyed to unit goals and activities. Activities include classroom games, filmstrips, displays, stories, construction projects, library research, map work, role playing, painting, outdoor games, discussions, attitude surveys, field trips, civic writing, and symbolic activities. The unit evaluation is based on observations, students' work products, and participation. A 12-item annotated bibliography is attached. (JDH)
