In this activity, students use knowledge about the five food groups to plan and produce a group meal, and determine which ingredients were produced locally and which came from farther away.
Students will learn how limited productive soil is as a natural resource on Earth. The students will visually see how very little soil there is available for growing all of the food, fiber, and lumber for the ever growing world population.
Students will discover that soils physically and chemically filter impurities out of water. They will also discover the role of soil in having good drinking water.
Students will understand that topsoil is a limited resource with economic value. Activities include slicing up an apple to demonstrate the distribution of Earth's soil resources and exploring scenarios involving the dollar valuation of soil.
Students will use the story of The Empty Pot to explore literature and science, practicing story mapping and learning about the needs of plants and the importance of soil and water.
Students identify their perceptions of erosion by examining images of mountain and agricultural landscapes and discussing which environment is more erosive.
Describe a watershed and delineate a watershed on a map; Identify the key factors in a watershed that impact runoff and sediment yield, describe how increased storm-water runoff affects landscapes (e.g., erosion, channel incision, sedimentation) and describe how those factors are impacted by human development;
