Drought Resources and Information
The Drought Resources and Information Web site is maintained by the Utah State University Extension Water Resource Issues Team, which was created to "address information needs related to water conservation and quality in agriculture and urban settings." The site provides information on several subjects including landscape irrigation, agricultural water uses, home water conservation, drought and weather monitoring, and more.
National Association of Agricultural Educators
The National Association of Agricultural Educators (NAAE) "seeks to advance agricultural education and promote the professional interests and growth of agriculture teachers as well as recruit and prepare students who have a desire to teach agriculture." In addition to information about membership and the upcoming NAAE Convention, the site features resources and information relating to advocacy. The Advocacy section contains Legislative Alerts, information about communicating with members of Cong
Mission to Mars
This educational module is designed to teach students about models and data collection and analysis using a Mars Mission as an example. The activities in this module require students to gather observations and data and use this to generate a model that illustrates a real object, in this case, the surface topography of a landing site on Mars. This module allows for students to have increasingly sophisticated experiences with this concept as well as an opportunity to utilize science process skills
Quick take on Pheonix Mission to Mars : follow the water
Following water continues to guide exploration even as space is explored find water and you might find life itself. One such mission that is following the water is the Phoenix Mars Lander project. On August 4, 2007, the lander was launched on its 10-month journey to the Red Planet. Phoenix will land on the northern plains of Mars and dig into the soil and water-ice seeking the Martian Holy Grail: water and possible life-supporting conditions.
Efficiency of a water heating system
Students use a watt meter to measure energy input into a hot plate or hot pot used to heat water. The theoretical amount of energy required to raise the water by the measure temperature change is calculated and compared to the electrical energy input to calculate efficiency.
The Earth rotates through days
The students will be a part of a model showing how the Earth's rotation creates what we see as a sunrise and sunset every twenty-four hours.
Multi System Degeneration - Coordination Exam - Lower Extremities Sub-exam - Patient 6
Patient's speech is difficult to understand; loss of balance (fell off a truck); occasional choking spells, especially if he eats fast; bladder urgency; and slight impairment of memory. The patient returns for a follow-up with his wife. Since the last visit, he reports no significant changes. His speech is unchanged. Balance is the same with occasional falling. He has occasional choking spells, especially if he eats fast. He continues to have bladder urgency and an occasional accident, but he a

Diversity of leaves
The diversity of land plants can be seen in the diversity of their leaves. Leaves vary by color, vein arrangement, shape, texture, and thickness.
The Difference Between Feeling and Emotion
Antonio Damasio, noted researcher and professor of neuroscience at USC, talks with The New York Times' David Brooks about emotions and the science of being human. Here, he describes the difference between emotions and feelings and explains why emotions are one of humanity's most important survival mechanisms. (05:09)

2.1 Working through the section
This unit examines Hume's reasons for being complacent in the face of death, as these are laid out in his suppressed essay of 1755, ‘Of the immortality of the soul’. More generally, they examine some of the shifts in attitude concerning death and religious belief that were taking place in Europe at the end of the eighteenth century, through examination of this and other short essays.
