Starting with Soil

Soil is more than dirt under our feet. Students ages 7-9 can use this Starting with Soil app to learn about the organic materials that make up soil, and how plants and animals work together to make the soil that we depend on to grow food. With this app, developed by the Center for Ecoliteracy, students can simulate the 500-year process of making 1-inch of topsoil by planting seeds and building compost. The app can be accompanied with classroom instruction or students can use it on their own.
