Brainstorm: 1. Density Independent Physical Factors: Make a list of at least 10 physical factors that will affect the population size regardless of population density. Example: Rainfall 2. Density Independent Catastrophic Events: Make a list of at least 10 catastrophic events that will affect the population size of cougars regardless of population density. Example: Hurricane 3. Density Dependent Factors: Make a list of at least 10 factors that would have a greater effect on population size if there is greater population density. Example: Competition

Limiting Factors Group Brainstorm: 1 Limiting Factors Group Brainstorm: 1. QUIETLY collaborate with group members to brainstorm limiting factors 2. Everyone should WRITE down ideas in brainstorm box 3. HYPOTHESIZE in space provided beneath the brainstorm box
