IV. EARTHWORKING AND EARTH RESOURCES
Learning Objectives: In this unit you will learn how to survey the land prior to earth moving by measuring slope and area, operate a front loader and back hoe (if available on site), what it takes to shape dams, ponds, swales, terraces, foundations for houses, and other earth constructs. You will explore the differences of a diversity of soils and what it takes to shape them.
