What is soil made of?

Recently Feed the World alumni educator Jeff Jostpille’s 8th grade science class at Fort Jennings High School learned the basics of soil: the components that form it and the weathering process that affects it. They also learned about soil texture and particle size.

In the lab, each pair of students were assigned soil from around the local area to use in the soil texture lab. These samples were taken from farm fields, lawns, garden beds, etc. Students measured soil and water into a graduated cylinder and let them sit overnight.

The following day they measured the different layers, found the percentage of each, and used the soil texture triangle to determine the soil type they had been assigned.
