Description
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. Kit accommodates 30 students working in pairs. Kit includes perishable materials when shipped. For best results, use perishable materials within 2-3 days of receipt.
