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. Activity Sheet 5, Question 7 (See page 46 in Teacher's Guide for sample answers.)

Class discussion of activity (See Guiding the Activity Step 6 on page 49 in Teacher's Guide.)

 Activity Sheet 5, Question 7:

Students should be able to answer this question completely and correctly without any teacher support.

Class Discussion:
  • Do students understand that the small rocks found in soil are formed from weathering? Note: Weathering can be a difficult concept for children. This is their first introduction to the term. In the Earth's Changes unit, students will study weathering extensively.
  • Do students know that when weathered rocks, sand/silt, and plant/animal remains are mixed, soil is formed?
