Experiments In Static Electricity

Science Bulletin

Rub a clean dry glass flask vigorously all over with a piece of silk, and roll it about in a pile of very course cork dust or a quantity of crumbled bits of dry corn stalk pith. When the flask is lifted it will be covered with dust or pith, the particles of which it will proceed to fire off in different directions, some to considerable distance.

What Kind Of Weather For Tomorrow, E. J. Cable

Science Bulletin

One of the most common topics of conversation when friends or strangers meet is "what a fine day," or "what terrible weather.'' No natural phenomena have a more pronounced psychological influence upon man than weather phenomena.

Cosmic Rays As Barometers

Science Bulletin

Prof. R. A. Millikan, discoverer of the Cosmic rays, has recently reported to the National Academy of Science a practical use for those rays. These are the most penetrating radiations known, far exceeding X rays and even the very penetrating gamma rays of radium in that respect.

Plant Disease, C. W. Lantz

Science Bulletin

Many educated people do not realize that a plant may be diseased as truly as a human being; at least they have little conception of the nature and significance of plant disease. In an agricultural state such as Iowa this is an important question and some time can very profitably be given to the study of plant disease either in the biology course or in the agriculture course.

Textbooks On General Science

Science Bulletin

Many requests have come to us for information concerning elementary and high school science textbooks. The kind most often mentioned have been those on general science. We are therefore printing below a list of such books, with a brief statement of content in each case.

The Effects Of Weight Cutting, H. Earl Rath

Science Bulletin

During the last decade, wrestling has increased rapidly as a high school as well as a college sport. About this time of year in those high schools where wrestling is listed as an interclass or interschool sport, the coach is anxiously looking over the material available and trying to mentally arrange them into groups according to the classes in which they will have to compete.

Carbon Dioxide: Experiments For General Science, O. B. Read

Science Bulletin

It is quite generally thought that an elaborate equipment of test tubes, flasks, beakers, dishes and desks are needed for any experiment involving chemistry. There are, however, many simple and instructive experiments that may be tried with only common household apparatus.

About Static Electricity, L. Begeman

Science Bulletin

Static charges of electricity occur in two forms, viz.: positive charges and negative charges. We now know that a negative charge consists of an aggregate of small particles called electrons and that a positive charge consists of an aggregate of small particles called protons. These electrons and protons may with equal correctness be considered particles of matter or particles of energy.

The Physiology Of Physical Condition, H. Earl Rath

Science Bulletin

Some men willfully break training rules because they think more of their own personal pleasure than they do of the success of the team or their own success as athletes. The treatment, if any, for this sort of individual must be mental. Many boys fail to observe training rules because they do not know what good physical condition is, or because they do not see the necessity of doing certain things in order to obtain it. It is for this latter group that this article is written, with the hope that it will make easier the grind of training by …

The Questionnaire

Science Bulletin

The request for suggestions which was sent out with the September number of the Bulletin brought a flood of unexpected magnitude. The editor was quite inundated, and even now has only partially emerged. But it was a welcome flood, which showed clearly what the science teachers of Iowa wish in such a bulletin-wish individually. Collectively they are not in all respects agreed.

Environment As A Factor In The Growth And Distribution Of Plants, O. R. Clark

Science Bulletin

The form and appearance of plants and the activities which they carry on are due in large part to the inherited characteristics of their ancestors. The influence which heredity exerts should be clearly and forcefully presented to students. At the same time the expression of the hereditary traits may be greatly modified by the conditions under which! the plants grow.
