Students will work in small groups to dig holes 1 meter deep. Students will work with measurements as they dig and measure. Students will observe the different types of soil and how the soil changes as they dig. Students will write and draw in their journals about the soil horizons. The need for soil as an important natural resource will be discussed. This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project, funded by the Malone Family Foundation.
