Activity 3.1: Carbon Pools (20 min)

Building on the biomass pyramid data from Lesson 2, students are introduced to the concept of organic and inorganic carbon pools and review carbon transforming processes that connect the pools. The Large Scale Four Questions are introduced.

Resources Provided

Setup

For Activity 3.1, open the 3.1 Carbon Pools PPT and project it. Prepare enough copies of the 3.1 Carbon Pools reading for each student to have one.

Directions

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

Show slide 2 of the 3.1 Carbon Pools PPT.

Assessment

  • Use the discussion of the 3.1 Carbon Pools reading to assess students’ understanding of carbon pools.
  • This unit builds on previous knowledge about organic versus inorganic carbon and the carbon-transforming process of photosynthesis, biosynthesis, decomposition, and cellular respiration. If students experience difficulty making the connections in this lesson, they should be provided further instruction or review before moving on.
