The Forward Pass In Football, Philip F. Murphy
The Forward Pass In Football, Philip F. Murphy
Bachelors’ Theses
This is a brief account of the Forward Pass and the part it plays in modern football. It is the study of conditions as they are today and as they were yesterday.
Line Play, William J. Wamtulonis
Line Play, William J. Wamtulonis
Bachelors’ Theses
Prior to 1896 the rules did not require more than one man on the line of scrimmage when the ball was put in play. Under these rules, the famous "flying wedge" was developed, in which ten of the eleven men were in motion when the ball was snapped. The rules were later changed, requiring five men to be on the line of scrimmage when the ball was put in play. This rule, together with its companion rule that "no player shall take more than a single step before the ball is put in play, save the one man who may …
Line Play In Football, Francis J. Linscott
Line Play In Football, Francis J. Linscott
Bachelors’ Theses
Line play in football has gradually evolved from a massed attack, as prevalent in the early eighties, to an open game that is in vogue today. Participants in the early days of football called this a "block game." The team in possession of the ball would not make any attempt to advance it if they were playing a superior team. This evil became so great, however, that a rule was enacted, whereby the team in possession of the ball must advance five yards in three scrimmages or suffer a penalty of ten yards. This was changed later on, and a …
Some High Lights On Science Club Work
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
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
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
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.
Progress Of The Junior Academy Of Science Movement, Louis A. Astell
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.

The Iowa Academy Of Science: Editorial
Science Bulletin
The Iowa Academy of Science will hold its annual meeting at Cedar Falls, on April 29 and 30. The Science Faculty of the Iowa State Teachers College will be hosts to the visiting scientists this year, and plans are well under way for entertaining the two hundred or more visitors who will be here for the meetings. The membership of the Academy is made up of both men and women, most of whom are teachers in the various high schools, colleges, and universities of the state.

Venereal Diseases, H. Earl Rath
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
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
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
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
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.
The High-Powered Skunk, Roy L. Abbott
The High-Powered Skunk, Roy L. Abbott
Science Bulletin
I can think of no animal that is at once so provoking and repelling of attention as the common skunk. His bright little face, clean black and white fur, plume-like tail, and fat roly-poly body all invite one to take liberties with him, yet a single move towards such familiarity, and he is transformed instantly into a thing vilely incredible, paralyzing, stupefying, insufferable.
