Test 215: Allis-Chalmers Special K, Nebraska Tractor Test Lab

Nebraska Tractor Tests

All tractors tested at the Nebraska Tractor Test Laboratory were certified by their manufacturers as being stock model machines, conforming to specifications filed with the application for test. No special or high-test fuels were used except as recommended by the manufacturer as necessary.

All results within the official tractor test report were actually attained in tests and are without correction or allowances for friction, temperature, altitude, etc. The results were initially accomplished with the tractor in charge of skilled operators employed by the University.

Unless otherwise noted, each tractor was apparently in good condition at the end of the testing …

Science In The Elementary School, Ethel Queeman Weller

Bachelors’ Theses

Through this discussion of the aims of education and the relation of science to these aims, one may readily see that science deserves a place of importance in the curriculum of the elementary school.

The Relative Merits Of Teaching Schorling And Clark Mathematics Without The Aid Of Drill, Compared To Teaching It With The Aid Of Two Kinds Of Drill, Edward E. Royse

Electronic Theses & Dissertations

This study attempts two things: (1) to find if Schorling and Clark Modern Mathematics, one of the adopted texts of Kansas, provides enough drill in the eighth grade; and (2) to weigh the value of two kinds of drill, viz., a flash-card machine and a drill test book.

Is High School Chemistry A Preparation For College Chemistry, Mansfield Martin

Masters Theses & Specialist Projects

The subject of this study grew out of a desire to estimate the value of high school chemistry and its relation to college chemistry. The purpose is to bring about a better understanding of the necessity of a closer tie-up between different levels of our educational system. Life and growth are continuous processes, and, if education if life, we must make it a continuous experience. While limited because of incomplete records and changing classifications of our high schools, it is hoped that this study will lead to a further and more scientific study of related problems in this field.

Some High Lights On Science Club Work

Science Bulletin

"The success of the club is of course more dependent upon the director than upon any other one factor. The director should take no active part during the meeting, except when it is necessary to carry the boys over what is to them an insurmountable difficulty-his frame of mind should be that of a man behind the scenes, who having set the stage stands by watching the performance, ever-ready to step into a situation and set things right. The ability to do this properly comes with practice. It does not demand exceptional ability or personality - Next to efficient leadership, …

The Place Of The Green Leaf In The World, C. W. Lantz

Science Bulletin

Why is a leaf? Ask the question of twenty-five of your friends and if five can give the correct answer I will be surprised. The green leaf is the food factory for the world. It is the plant organ that captures the energy of the sun and in the process of photosynthesis builds of carbohydrates from carbon dioxide and water and stores this energy in potential form. Later, through oxidation processes, this energy is released and does most of the work of the world. The green plant connects the inorganic world with the organic world and our energy is directly …

Colloids, R. W. Getchell

Science Bulletin

The increasing importance of the chemistry of colloids is giving them a wide recognition in the general chemistry texts of college grade. In a lesser degree they are included in the high school books but the information is often so condensed as to offer little of value. The writer believes that two or three class periods near the end of the year's course should be devoted to this subject and this article will attempt to present basic fact upon which may be built a discussion of colloids for high school pupils.

Concerning Cottontails, Roy L. Abbott

Science Bulletin

The cornfield lay above a low bluff overlooking a swamp, and for half an hour I had tracked that cottontail through a perfect maze of weeds and cornstalks. Warming with the chase, I was determined to have that particular bunny if it took me all morning. if I had not known better, I would have thought he was teasing me. Time and again, his tracks led into a bunch of grass with every indication that he was there for the day, but always they led out on the other side.

Teaching Of General Science In The Junior High School, Joseph T. Petska

Bachelors’ Theses

In this age of science and materialism there is not in the writers opinion, a more enriching course in our high schools as is a well balanced, well organized course in general science! It is enriching because, if taught well, it functions in the lives of the learners, it bridges the gap between the life of the learner and his environment.

The writer feels that the work in general science is of great importance and is worthy of the best thought of those responsible for the details of the courses in this subject in the junior high school. In spite …

Progress Of The Junior Academy Of Science Movement, Louis A. Astell

Science Bulletin

For the past three years, the Conference of State Academies of Science has officially considered the development of the Junior Academy movement. It is of interest to note that a number of State Academies are known to be considering Junior organizations or to have such organizations in various stages of development. These Academies lie in a more or less arc-like area through the United States.

Venereal Diseases, H. Earl Rath

Science Bulletin

Much has been said about what ought to be done about venereal diseases. Nearly everyone agrees that more education on the subject is needed, but that is about as far as it goes in at least ninety-nine cases out of a hundred. The result is that much erroneous information is surreptitiously passed about. Some young people have an abnormal fear of venereal disease and live in dread of acquiring it from all kinds of objects. Others, and this group is entirely too large, treat the subject entirely too lightly, and fail to respect the dangers involved.

Wings, Roy L. Abbott

Science Bulletin

When 'wings' are mentioned, most people at once think of birds. But wings, and the consequent power of flight, are by no means limited to birds. Among the mammals, for example, bats have wings and are excellent flyers. In both birds and bats, the wings are merely modified front legs.

The Project In Chemistry, Donald D. Pettit

Science Bulletin

Some time ago the writer became convinced that the typical presentation of high school chemistry left many things to be desired, especially with that group who are completing their scholastic work with their high school diploma. As a rule they are leaving school pretty thoroughly disgusted with class work in general, and, although they had originally intended to continue in school as evidenced by their election of chemistry, they find that the prospect offers no allure. In many cases I am afraid that the course in chemistry helped to turn them from further scholastic endeavor. In order to furnish some …

A Great American Scientist, W. H. Kadesch

Science Bulletin

"Dr. Albert A. Michelson, 78, discoverer of the speed of light, and one of the greatest scientists of modern times, died here at 3 :10 p.m. Saturday. "Death came quietly to the man whose work made it possible to know the distance of the stars. "It came on the eve of success of what he called his 'last experiment,' the most precise and extensive in physics-the exact determination of the speed of light." So ran the opening paragraphs of a long and appreciative front page article in the Des Moines Sunday Register of May 10, 1931. And in a similar …

Waves, L. Begeman

Science Bulletin

Of all the phenomena of the physical world, none is more important than that of waves. The average individual naturally assumes that the only waves of any importance in nature are water waves. To the student of science, however, there are other waves in nature far more important than those which we see rolling over the surface of a lake or of the ocean.
