Students investigate: How do changes in resources, space, and environmental conditions influence the size of a population over time? Beginning with a Carrying Capacity Challenge Lab, teams analyze population data, habitat maps, species needs, group behavior, and environmental changes to model how limiting factors affect survival and biodiversity. With guidance from zoo, aquarium, or nature center educators, students develop, rehearse, critique, and revise an evidence-based case study that defends whether a habitat can support a given population and recommends conservation solutions. At a Species Survival Summit, teams present their findings to peers and community guests, while weekly reflection circles help students track growth in carrying-capacity knowledge, persistence, listening, and teamwork.

Students will analyze population data, habitat maps, and species needs to explain mathematically how resources, space, environmental conditions, and group behavior affect carrying capacity, biodiversity, survival, and reproduction. Through the Carrying Capacity Challenge Lab and consultation with zoo, aquarium, or nature center educators, students will evaluate evidence about how environmental changes can increase populations, contribute to new species over time, or lead to extinction. Teams will create, rehearse, and revise an evidence-based case study that defends whether a habitat can support a given population and identifies relevant limiting factors and conservation solutions. Students will present at the Species Survival Summit and use weekly reflection circles, peer feedback, and shared decision-making to strengthen scientific reasoning, communication, persistence, listening, and teamwork.

Teams will create annotated habitat maps, population graphs or computational models, and species-needs profiles using evidence about food, water, shelter, territory, group behavior, and environmental change. Each student will maintain weekly reflection notes identifying one carrying-capacity insight and one growth area in persistence, listening, or teamwork. Teams will develop a short case-study presentation defending whether a habitat can support a given population, then revise slides, speaking points, and evidence connections after rehearsal feedback from classmates or zoo, aquarium, or nature center educators. The final product will be a Species Survival Summit presentation for peers and community guests that explains limiting factors and proposes evidence-based conservation solutions.

Kick off with a Carrying Capacity Challenge Lab where teams rotate through habitat stations featuring maps, food-and-water clues, territory constraints, and changing animal-population scenarios. Students model how each new condition affects population size, record evidence, and decide which limiting factors matter most. A zoo, aquarium, or nature center educator introduces a real conservation challenge and answers student questions about species needs, group behavior, and habitat change. Close with teams sharing initial claims and generating questions around: How do changes in resources, space, and environmental conditions influence the size of a population over time?

Host a Species Survival Summit where teams present case studies to peers, families, and zoo, aquarium, or nature center educators. Using evidence from the Carrying Capacity Challenge Lab, population data, habitat maps, and species needs, students defend whether a habitat can support a given population and explain how resources, space, environmental conditions, group behavior, and other limiting factors affect survival. Before the summit, teams rehearse with classmates or community partners and revise their slides, speaking points, evidence connections, and conservation solutions based on feedback. Conclude with an audience Q&A and reflection circle in which students share one insight about carrying capacity and one area of growth in persistence, listening, or teamwork.
