4.3: How Fluxes Change and Carrying Capacity (40 min)

In this activity, students use a more sophisticated model of carbon pools and fluxes to explain that carrying capacity is determined by the maximum photosynthesis rate

Materials You Provide

  • Computer (1 per student of pair of students)

Resources Provided

Setup

Print a copy for each student of 4.3 Computer Model for Changing Fluxes Handout and 4.3 Computer Model for Changing Fluxes Worksheet . Set up a computer and projector for 4.3 How Fluxes Change and Carrying Capacity PPT.

Directions

1. Use the instructional model to show students where they are in the course of the unit.
