This hands-on activity is an excellent (and tasty) way to get your students excited about soil science! Nothing says fun like food, right? In this activity, students will create and explain their own soil profiles using common food items.
Once they decide on what materials they will use, they are required to explain WHY they chose the materials--this allows for excellent teacher checks, informal assessment, and a chance for higher order questioning! Students then draw their soil profile on the provided worksheet and measure the 'depth' of each layer, before finally estimating how long it took their 'profile' to form.
Opportunities for differentiation include: choice of student material, creating different profiles from around the world (pedocal, pedalfer, laterite), creating and comparison of 'ideal' soil profiles vs 'exhausted soils', tie-ins to the Dust Bowl and soil sustainability.
