Soil is the linchpin of the environment, where atmosphere, biosphere, and hydrosphere meet. Despite that, many students see soil as “just dirt” – a place to grow plants, but nothing more. Soil science educators are challenged with the task of helping students and the public recognize the critical importance of soil in the environment.
A collaborative project by soil science and earth science teachers at University of Nebraska-Lincoln, Oregon State University-Cascades, Colorado State University-Fort Collins, Trinity College, and University of Minnesota explored the development and dissemination of soil e-lessons. By harnessing technology, the instructors created learning tools that could reach beyond their classroom walls to teach other students and public audiences about soils as well.
The project, which is featured in the 2009 edition of the Journal of Natural Resources and Life Sciences Education (JNRLSE), aimed to develop and promote the use of online lessons to educate college students and the public about role of soil in addressing food, energy, and environmental issues. To engage learners, the developers focused on the inclusion of active learning strategies, interactive Flash animations, experiential learning activities, transfer problems, embedded questions, images, and text as primary instructional elements. All activities were contained in a web-based format to make them easy to use and share. Development of the e-lessons was supported by a National Science Foundation Course, Curriculum, and Laboratory Improvement Program Award.
The University of Nebraska-Lincoln’s “Plant and Soil Sciences eLibrary” showcases lessons developed for the program. It features activities on topics such as rocks and minerals, weathering processes, soil forming factors, processes of soil profile development, and soil taxonomy and geography. The lessons cover the fundamentals of why soils are what they are, and how they came to be that way. Developers believe these basic lessons will spark further interest in soil, and help learners recognize soil as an essential part of the environment.
The e-lessons can be readily accessed through the University of Nebraska’s Plant and Soil Sciences eLibrary, under the section entitled “Soil Genesis and Development” at: http://plantandsoil.unl.edu/croptechnology2005/soil_sci/

Today's educators are looking to the Journal of Natural Resources and Life Sciences Education, http://www.jnrlse.org, for the latest teaching techniques in the life sciences, natural resources, and agriculture. The journal is continuously updated online during the year and one hard copy is published in December by the American Society of Agronomy.
The American Society of Agronomy (ASA) www.agronomy.org, is a scientific society helping its 8,000+ members advance the disciplines and practices of agronomy by supporting professional growth and science policy initiatives, and by providing quality, research-based publications and a variety of member services.

At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
