Read an exciting science mystery about killer bees online, evaluate a list of clues, and try to answer the questions correctly. The story responds to the reader's choices and presents research material for the next step. Though the educational value of this instructional activity is limited, its entertainment value is high. Have lab groups work on this during a rainy day in the middle of your study of ecosystems or animals. It is a terrific way to engage students who aren't normally interested in science.
