The ADAPT Program for college freshmen was offered at the University of Nebraska Lincoln from 1975 to 1997. The program always included two semesters of three credit hours of physics. The fall semester of laboratories is given in this pdf file. The physics topics were arranged to develop more and more advanced reasoning and data analysis skills, from linear functions to power law functions to exponential functions. These analysis skills required the students to master Cartesian graphs, log-log graphs and semi-log graphs. All of these laboratories were organized according to the Robert Karplus learning cycle. Near the end of the …

Energy In Perspective Laboratory #4: Finding Relationships, Robert G. Fuller

ADAPT Lessons: Physics

A group of ADAPT students took the Starship Enterprise to the planet Kunzonia. When they arrived, they felt funny. Their heads seemed light and their feet seemed heavy. To try to understand the force of gravity on this planet, they made a simple swinging device fashioned from equipment on the starship. It was a flat bar with a pivot at the top and three equally-spaced holes along its length. The students used masses of 200 g, 400 g, and 600 g (which could be attached in the holes), a meter stick, and a timer, and let the bar swing to …

Energy In Perspective Laboratory #5: Working With Triangles, Robert G. Fuller

ADAPT Lessons: Physics

Dear ADAPT Students,
We think that these plane figures can be organized into groups that share common properties. We went to Pythagoras but he died before he could tell us much. His last words were,
"Take measurements and focus on ratios..."
Beside his death bed we found 27 different pieces of cardboard cut into a variety of right triangles of various sizes and shapes. Please put the triangles into different groups that display at least two common characteristics and be prepared to explain to your instructor how you did it. You may wish to make a table of your measurements …

Ec88-116 Universal Soil Loss Equation: A Handbook For Nebraska Producers, A. J. Jones, D. Walters, W. G. Hance, Elbert C. Dickey, J.R. Culver

University of Nebraska-Lincoln Extension: Historical Materials

Tons of soil are lost from agricultural fields in Nebraska each year as a result of water erosion. The accelerated loss of topsoil reduces the availability of plant nutrients and water needed for optimum crop production. In addition, the eroded soil frequently moves into surface waters causing sediment to be deposited in streams and reservoirs and nutrients to be released into other biological systems. The purposes of this workbook are to provide an understandng of how soil erosion estimates are determined, to estimate erosion control resulting from numerous cropping systems, and to inform the producer of alternative practices which may …

G87-856 Hedges, Don Steinegger

University of Nebraska-Lincoln Extension: Historical Materials

Hedges can be an attractive and functional part of home landscaping. This NebGuide outlines the steps for proper plant selection and establishment, care, and rejuvenation.

Not only are hedges attractive, but they serve some important landscape functions. Hedges, particularly sheared ones (formal), require time and some knowledge to establish them as well as annual pruning. It is also important to select suitable plant material and an appropriate site to minimize upkeep. Rapid growing plants like privet require more frequent shearing. A shady site or one with little air movement may require spraying for disease control.

Hedges mark boundaries such as …

G87-838 Management Of Greenbugs In Sorghum (Revised May 1994), Robert J. Wright, Stephen D. Danielson, Zb Mayo

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes the identification, biology and management options for greenbugs in Nebraska sorghum.

The greenbug is the most important insect pest of grain and forage sorghums in Nebraska. Although numbers fluctuate from year to year, greenbugs are a limiting factor to sorghum yield in most years. Their management is complicated by the fact that greenbugs have been able to evolve populations capable of overcoming plant resistance and organophosphate insecticides, so best management practices continue to change over time.

Another common aphid found in sorghum is the corn leaf aphid. Corn leaf aphids are often mistaken for greenbugs; however, they …

In 1983, more than $45,000 worth of feeder pigs were electrocuted on another Nebraska farm. Dairy and beef animals also have been electrocuted--as have producers. A survey of more than 400 Nebraska farms revealed that over 50 percent have problems due to poor on-farm wiring. A more recent survey of 14 farms revealed none with 100 percent properly wired buildings. Many had conditions which were serious …

G87-828 Growing Perennials, Don Steinegger, Anne Streich

University of Nebraska-Lincoln Extension: Historical Materials

Planning, soil preparation, and maintenance are necessary in growing a perennial garden of color and interest throughout the growing season.

Herbaceous perennials are non-woody plants that live two or more years under local conditions. The above ground parts of these plants are generally killed to the ground by frost in the fall, but the roots and/or underground parts live through the winter. Growth is renewed and the cycle begins anew in the spring.

While perennials do not require yearly replanting, they still require regular maintenance. For best results, a proper site analysis, soil preparation and routine maintenance are necessary. With …

G87-831 Identification Of Soil Compaction And Its Limitations To Root Growth, Alice J. Jones, Elbert C. Dickey, Dean E. Eisenhauer, R.A. Wiese

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide will help you identify soil compaction and determine if compaction is limiting yield. Soil compaction is primarily caused by working or driving on wet fields. Compaction can develop at or below the soil surface (Figure 1) and can lead to inefficient fertilizer and water use and reduced yields. Observation of crop growth and soil surface conditions can give clues as to the extent of soil compaction.

Heg87-223 Understanding Grief And Loss, Herbert G. Lingren

University of Nebraska-Lincoln Extension: Historical Materials

This guide defines loss, offers guidelines for dealing with grief and loss, presents psychological and emotional responses to loss, and describes ways to help people deal with bereavement.

Loss is defined as a "separation from, a detachment from something or someone of value." The magnitude of the loss and its meaning and value to the individual affects the intensity of a person's response. Therefore, it is virtually impossible to predict how any one person will respond to a particular loss. But it always causes some change in perception of one's self or lifestyle and some type of adaptation or adjustment …
