(Optional) Activity 3.4: What Happens to Soil Carbon (20 min)

In this activity, students discuss what happens to soil carbon.

Resources Provided


Prepare one copy of 3.4 Food Webs Video Worksheet for each student. Prepare a computer with a projector to display the video.


1. Introduce students to the “extensions” in this Activity: a video.

Tell students that in this activity, they will be think about what happens to the carbon that ends up in the soil through death, feces, and defecation.


During this activity, check to see if students are making connections between the cycling of matter between pools they learned in previous activities with the content of the video.


Watch the video a few times to help students become familiar with the content.


Instead of using the 3.4 Food Webs Video Worksheet, have students discuss the video as a whole class afterwards.

Extending the Learning

Have students write and perform their own skit or song that models matter and energy cycling in an ecosystem.
