Activities in this unit are designed to sensitize students in grades 4-6 to the needs of animals and to the injustices many species suffer. The lessons focus on inhumane acts such as the use of steel-jaw traps, dogfighting, hunting, keeping exotic pets in captivity, using animals in entertainment, habitat destruction, factory farming, and animal experimentation. Materials include a class rating scale, student questionnaire, vocabulary worksheet, crossword puzzle, word jumble, secret code, student research report, letter-writing exercise, and sample petitions. Teaching plans are provided for a total of 12 lessons involving health sciences, social studies, math, and language arts. A teacher's answer key and suggested resources are also provided. (LH)
