Students are introduced to the Dust Bowl and determine how to avoid another event like it in the future as they study soil texture, particle sizes, soil nutrients, and pH. Grades 6-8

Students observe soil ecosystems to investigate how human impact affects the biodiversity of soils using the Simpson's Index of Diversity. Then, students conduct an investigation using field corn to determine how the introduction of nitrogen fertilizers impact soil microorganisms and biodiversity. Grades 9-12
