Grades 6–8. For a class of 30. The school mascot has been taken, and it's up to your students to solve the mystery before the big game! Was it one of the rival schools? In this cross-curricular investigation, students examine a note, some strange-looking leaves, a mouth guard, and some white fibers that were left at the scene. After fingerprinting the culprit, students stage a trial. Activities include analyzing DNA results; using dichotomous keys to identify selected plants; analyzing handwriting, fingerprints, and bite marks; as well as a fiber flame test. Kit includes activity materials, a teacher's guide, student worksheets, and casebooks.
