Soil is all around us, in fact there is so much of it that we often don’t think of it as a valuable natural resource, and we might even take it for granted! We rely on its productivity for our food and fiber and its firmness to support our buildings and roads. With this series of active-learning exercises, your students will practice scientific inquiry while learning about soil as a valuable resource. After demonstrations on the amount of soil covering Earth and how it is retained/eroded, students work creatively as “farmers” to prevent soil erosion and save their farm, learning about a real-world problem.
