Discuss how young sea lions often don't survive the first few years. Divide students into teams of four or five. 3. hunting for food takes skill - put poker chip between knees and drop in milk carton. Each student takes a turn running the course, stopping at each challenge in the lane. You may want each student to read the Challenge Card aloud or show it to other team members.
Student drops card and continues.
Then determine sea lion survival rate by team. Try the game again. An ecosystem is ever-changing. Weather, ocean currents, disease, and food availability can all change the number of predators or prey or the haul-out sites. Sometimes humans can positively or negatively affect an environment.
