This lesson introduces the idea of soil as an ecosystem and as a carbon sink.

 

Step 1 - Inquire: Students view a timelapse video that demonstrates the difference between soils with and without invertebrate decomposers.

 

Step 2 - Investigate: Students learn about the concept of soil as a carbon sink and examine soil samples to learn how to define soil.

 

Step 3 - Inspire: Students draw and record their findings, demonstrating understanding of soil as an ecosystem and create a model of their soil artistically using found materials in the classroom.
