Students' Knowledge And Perceived Confidence In An Interdisciplinary Experiential-Learning Environment, Lee J. Florea, Adam J. Kuban, Michelle O'Malley

Lee J Florea, PhD, P.G.

Experiential-learning theory suggests that students acquire knowledge through hands-on learning environments, and aspiring journalists need a setting where they can experience science — its process(es) as well as how to report empirical findings. Researchers utilized pre/post questionnaires, field-notebook evaluation, and focus-group analysis as methods to assess an interdisciplinary, experiential course that combined science and media undergraduates. Results revealed students valued procedural over fact-based knowledge. Students also indicated increased perceived confidence—even when they answered questions incorrectly.

G08-1491 Drinking Water Treatment: Water Softening (Ion Exchange), Sharon Skipton, Bruce I. Dvorak, Shirley Niemeyer

University of Nebraska-Lincoln Extension: Historical Materials

The presence of calcium (Ca) and/or magnesium (Mg) in water results in water being considered "hard." Calcium and magnesium ions in water react with heat, metallic plumbing, and chemical agents such as detergents to decrease the effectiveness of nearly any cleaning task. Hard water can be softened using an ion exchange softening process. This 2008 guide discusses the ion exchange water softening process and related equipment used for household water treatment.

Ec08-1552 Drinking Water: Arsenic, Sharon Skipton

University of Nebraska-Lincoln Extension: Historical Materials

Arsenic is a naturally occurring element present in rocks and soil. Arsenic is the 20th most abundant element in the earth’s crust and often forms compounds by combining with oxygen, chlorine, and sulfur. As water passes through and over soil and rock formations, it dissolves many compounds and minerals including arsenic. The result is that varying amounts of soluble arsenic are present in some water sources. Arsenic chemistry is complex because it has many forms.

This 2008 NebGuide discusses arsenic in public and private drinking water supplies.

Nf00-429 Controlling Pond Algae With Barley Straw, John C. Holz

University of Nebraska-Lincoln Extension: Historical Materials

Algae are microscopic, free-floating plants which comprise a critical component of a lake's food web. They are fed upon by tiny animals called zooplankton which are an important food source for fish. Algae color the water green or brown, and uncontrolled growth can lead to nuisance surface scums, poor water clarity, noxious odors and an overall reduction in the lake's recreational value. Excessive levels or "blooms" of algae occur when nutrients, especially phosphorus, are abundant. After taking steps to reduce the amount of phosphorus entering a lake, it may be desirable to control the algae growth directly. Typically this is …

Groundwater provides nearly all the water for domestic use in rural Nebraska. It’s essential that the quality of our groundwater, along with that of our surface water resources, be protected. It is especially important to protect the drinking water supply on any homesites where a private domestic well is used. The risk to water quality of various activities at homesites and on surrounding lands varies. Identifying high-risk activities can help determine where to use limited financial and management resources. By increasing knowledge and using careful management, you can greatly reduce the risk of water contamination, often with little or no …

Ec98-796 Farm*A*Syst Nebraska’S System For Assessing Water Contamination Worksheet 17: Stormwater Management At Residential Sites, Robert Grisso, Delynn Hay, Paul J. Jasa, Richard K. Koelsch, Sharon Skipton, Wayne Woldt

University of Nebraska-Lincoln Extension: Historical Materials

Stormwater is water from irrigation, rain or melting snow that does not soak into the ground. It flows from rooftops, over paved areas and bare soil, and across sloped lawns. As it flows, this runoff can collect and transport soil, pet waste, livestock manure, salt, pesticides, fertilizer, oil and grease, leaves, litter and other potential pollutants. A heavy rainstorm isn’t needed to send pollutants rushing toward streams, wetlands and lakes. A garden hose alone can supply enough water.

University of Nebraska-Lincoln Extension: Historical Materials

Waste is inevitable. Things which have been outgrown, broken, replaced, or are just no longer needed add to the waste produced at homes, acreages and around farms. Most of the waste accumulated around the farm, acreage and home is solid waste. Solid waste includes all discarded materials — newspapers, empty paint cans, liquids, gases, pickle jars, orange peelings, leftover food, worn out shoes, junk mail — this list is endless. Some of these solid wastes contain potentially hazardous materials.

Ec98-755 Farm*A*Syst Nebraska’S System For Assessing Water Contamination Risk Fact Sheet 13: Improving Milking Center Effluent Treatment, Robert Grisso, Delynn Hay, Paul J. Jasa, Richard K. Koelsch, Sharon Skipton, Wayne Woldt

University of Nebraska-Lincoln Extension: Historical Materials

Effluent from the dairy milking center, including discharges from the milking parlor (manure, feed solids, hoof dirt) and milkhouse (bulk tank and pipeline rinse water and detergent used in cleaning), is commonly disposed of in a variety of ways. Milking center effluent offers several unique challenges due to the presence of: 1. Large volumes of contaminated water which can overwhelm soil absorption systems. 2. Milk solids and fats and manure solids which plug many systems. 3. Cleaning sanitizers which reduce bacterial breakdown of solids. When these systems fail, effluent will become a risk to surface and groundwater quality.
