Grades 9-12. In this kit, students use direct observation and modeling to examine the relationship between predator and prey in 2 sets of organisms. First, students examine the relationship between Daphnia and Hydra and between Stentor and Chilomonas. Students then collect data while modeling a predator-prey relationship with beads. Students graph and analyze the collected data before drawing conclusions about the relationship between predator and prey.
