Let's Eat Some Dirt

4th grade just wrapped up their science unit on soil. We reviewed by making an edible soil profile, complete with 3 layers of soil (bedrock, subsoil, and topsoil) and different things you'd find in the layers. Plants and roots help slow erosion, and creatures like worms add to the organic material that gives topsoil its rich nutrients. We had a blast, and the kids loved "eating dirt!"
