This site provides a brief description of the Dustbowl in the American Great Plains during the 1930s and relates its effects to what is occurring presently in the Sahel of North Africa. In this dry savannah environment, human activity coupled with prolonged drought are causing desertification. The site features text, satellite imagery, and links to other related materials.

Students will learn about the water cycle, watersheds, and specifically, the watershed that feeds Springfield, Oregon. After analyzing drought maps, reading news reports, and seeing images and videos, students will realize that drought is a real life concern. Students, as concerned citizens, will create a water collection device, at first on a small scale, and then a true to life water collection system to help re- purpose rainwater in our garden area.

Students learn about soil properties and the effect biochar—charcoal used as a soil amendment—has on three soil types, sand, loam and clay. They test the soils’ water retention capability before and after the addition of biochar. During the activity, student teams prepare soil mixtures, make observations (including microscopic examinations), compare soil properties, conduct water retention tests, take and record measurements, and analyze their observations and data. They see how the physical properties of soils—color, texture, and particle size—can be indicators of nutrient content and water retention capabilities to support plant growth. From their findings, they consider biochar’s potential benefits for environmental and agricultural applications, especially in conditions of drought and depleted soils. An activity lab sheet is provided to guide experimental data collection and analysis.
