In this companion kit to the Introduction to Soil Kit LAB-1101
, elementary students continue their exploration of soil. In the first activity, students describe a soil sample, then identify the similarities and differences between their group's descriptions and those of other groups and develop a primary definition of soil. Activity 2 expands the investigation of soils by using a water column to separate soil samples into various components. This data provides more evidence on the types and proportions of the different materials in each soil and allows students to refine their previous definition of soil. Activity 3 is a reading which provides information that expands their personal experience and observations from the previous activities to deepen and refine their understanding of the composition, structure and development of soil.
