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.

Grades 9-12.

  • Observe and measure the population dynamics of duckweed in a closed system
  • Graph the population growth and explore the differences between exponential and logistic growth
  • Determine the carrying capacity of a closed system

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. Note: Kit is available with the perishable material included or with a prepaid coupon to request the perishable material later at your convenience.
