Carolina EcoKits®: Population Growth and Carrying Capacity (with perishable)

Item # 187000P Exclusive

Grades 9-12. The fast reproduction rate of duckweed makes it a perfect organism for studying population growth. Students first predict what changes will take place within a population in a closed system. They investigate their predictions by completing regular counts of the population over a 3- to 4-week period and then graph the population data, calculate growth rate, and determine the carrying capacity of the system. Kit accommodates a class of up to 30 students working in pairs.

The fast reproduction rate of duckweed makes it a perfect organism for studying population growth. Students first predict what changes will take place within a population in a closed system. After creating a closed-system environment for duckweed, students investigate their predictions by completing regular counts of the population over a 3- to 4-week period. Using the collected data students graph the population data, calculate growth rate, and determine the carrying capacity of the system. Kit accommodates a class of up to 30 students working in pairs and includes perishable material when kit is shipped.
