What makes up soil? Where do the parts come from?

4C(3-5)#2: Rock is composed of different combinations of minerals. Smaller rocks come from the breakage and weathering of bedrock and larger rocks. Soil is made partly from weathered rock, partly from plant remains—and also contains many living organisms.

Class discussion of lab observations (See Guiding the Session Steps 4-12 on pages 40-42 in Teacher's Guide.)

Class Discussion:

  • Do students know that soil is made-up of broken rocks and plants that were once alive? Note: As a result of this lesson, students should have a very clear understanding that plant (and animal) remains are one component of soil.
