Students use a spring scale to drag an object such as a ceramic coffee cup along a table top or the floor. The spring scale allows them to measure the frictional force that exists between the moving cup and the surface it slides on. By modifying the bottom surface of the cup, students find out what kinds of surfaces generate more or less friction.

Soil and Water Conservation: An Annotated Bibliography could become a model for future upper level undergraduate and graduate classes in Soil Science. A teaching philosophy that supports connecting students with sources of soil and water conservation information favors better knowledge and understanding of soil and water resources; it additionally builds links between students and those members of the profession writing about these key topics. This vision for supporting and supplementing education in this topic area is not totally new; however, creating a resource well suited to meet these goals is. This resource has met the forward-thinking goals of Dr. Moorberg: 1) create an easily available educational resource; 2) familiarize students with technical resources that are a foundation for soil and water conservation education; and 3) establish a science-based class resource with low or no cost to the student. The vision for and delivery of a credible, unique, and potentially impactful educational resource is to be commended by our teaching and research profession.

A cost-benefit analysis is a good way to weigh the costs and the benefits and compare them to see if the decisions being made are sound and worthwhile. For a hypothetical solar farm design problem, students are given a solar cost-benefit analysis sheet to complete within groups. They weigh the expense and benefits of two types of solar panels (with different costs, wattage outputs and land impacts), consider the cost of using the acreage for solar (which removes it from ranching use), and explain why they consider the panel combination they propose to be best. If the costs outweigh the benefits, then a project is not worth doing. On the other hand, if the benefits outweigh the costs, then it is worth implementing the plan.
Students learn about solar energy and how to calculate the amount of solar energy available at a given location and time of day on Earth. The importance of determining incoming solar energy for solar devices is discussed.
