Kansas Lesson Plan

Soil's Value

Lesson Plan
Students will watch an "Apple Land Use Model" demonstration and the division of an apple into the parts of the earth's surface to learn about the limited natural resource of topsoil available for growing all the food, fiber, and lumber for our ever-growing earth population. Students will model the demonstration using a ball of playdough. Through listening, observing, calculating values, and writing, students will study the surface of the earth and the available land for agricultural use.
