1.4 Human-induced eutrophication
Managing eutrophication is a key element in maintaining the earth's biodiversity. Eutrophication is a process mostly associated with human activity whereby ecosystems accumulate minerals. This unit explains how this process occurs, what its effects on different types of habitat are, and how it might be managed.

Assessing the learning process
Assessment, like instruction, needs to be geared toward various learning styles, and teachers can create rubrics for ongoing assessment that keep a formal daily record of what students are learning. Traditional styles of teaching focus almost exclusively on auditory presentation of material to students — in other words, lecturing. K–12 education is moving away from that traditional model towards methods of teaching that address children’s multiple intelligences and are appropriate to diffe

This course covers the relation of structure and function at various levels of neuronal integration. Topics include functional neuroanatomy and neurophysiology, sensory and motor systems, centrally programmed behavior, sensory systems, sleep and dreaming, motivation and reward, emotional displays of various types, "higher functions" and the neocortex, and neural processes in learning and memory.
NASA CONNECT PSA - The Astronaut's Helper
In NASA CONNECT PSA: The Astronaut's Helper, students will be introduced to the Personal Satellite Assistant (PSA), a small, spherical robot that assists astronauts with their chores on space-based vehicles. Students will learn about different types of robots and the mechanical systems on the PSA that must work together for the PSA to function. In the web activity, students interact with a simulation of the PSA and learn how forces affect motion in a low-friction, microgravity environment. Stude

National Water Information System Web Data for the Nation
This USGS site provides access to water resources data collected at approximately 1.5 million sites in all 50 states, the District of Columbia, and Puerto Rico. The site features real-time and historical data retrievable by geographic area for surface water, groundwater, and water quality conditions such as temperature, specific conductance, pH, nutrients, pesticides, and volatile organic compounds. The site also includes an extensive inventory of information about data collection sites at strea
The USGS has developed a national inventory of significant topographic changes based on seamless multitemporal elevation data and land cover data. The National Elevation Dataset (NED) and the Shuttle Radar Topography Mission (SRTM) data form a unique pair of seamless elevation datasets that can be used to detect and analyze 20th century topographic surface changes in the United States. The need for more comprehensive information on the nature and extent of recent human geomorphic activity led t
Descriptive Model of Au-Ag-Te Veins

Narrative vs. Expository Texts
Many students, especially students with limited English language skills, have difficulties determining the difference between narrative and expository texts. This unit will use vignettes written by Peace Corps Volunteers serving in Lesotho and Madagascar to compare these types of texts. As final products, students will write both a narrative essay and an expository essay. This unit was piloted with high school second language learners.
Peirce And Fisher on the Place of Probability in Abductive Inference
In his analysis of inference into three types, deduction, induction, and abduction, C. S. Peirce maintains that probability plays an essential role in the first two, but not in the third. For a deductive argument, probability tells us the frequency with which the conclusion will hold given the premises; for an inductive argument, probability tells us the frequency with which the argument will hold true. However, probability has no role to play in abduction because there is, in Peirce's view, no
