Health And Cleanliness, H. Earl Rath

Science Bulletin

A short time ago there was presented in the columns of this paper an article dealing with the methods of motivating a health program. This article dealt with the methods of gaining an interest in the subject of health. Once having gained this interest a program of education must be brought forward. Such a program may not be elaborate, in fact probably should not be. It is the opinion of the writer that most programs of health attempt to cover too wide a field and do not leave sufficient definite impressions.

The Air We Breathe, S. F. Hersey

In addition to the simple experiments already suggested attention is called to others which will show the common constituents of the air.

In A Recent Study Concerning The Status Of Science, The Following Interesting Facts Are Noted

Science Bulletin

In a recent study concerning the status of the sciences in Iowa high schools made here at this college the following interesting facts are noted as to the sciences offered.

Household Insects, Roy L. Abbott

Science Bulletin

It was said above (see November Bulletin) that practically every animal is attacked by one or more kinds of insects. Man constitutes no exception to this statement, and it is my purpose in this article to deal with a few of the insects commonly found in or around our homes. Perhaps the most familiar of all household insects is the housefly.

Motion, L. Begeman

Science Bulletin

Motion is a general property of matter. There is no rest in the absolute sense. An object at rest with reference to the earth 's surface is in rapid motion with reference to the earth's axis of rotation just as a person may be at rest in a Pullman car and at the same time be in rapid motion with reference to the ground. All divisions of matter, - masses, molecules, atoms, protons, and electrons are moving relatively all of the time.

Astronomy, E. J. Cable

Science Bulletin

In the field of general science, astronomy offers projects for practical as well as very useful knowledge. One of the greatest values is its appeal to the intellect. Astronomy attempts to unravel the secrets of nature, not only on our planet, but also in the vastness of space around us that is within reach of man's powerful instruments. It acquaints man with what is going on around him as well as with what is happening in regions far removed from everyday experiences and personal contacts. Astronomy tries to make man feel "comfortable" and at "home" in his universe.

The Air We Breathe, S. F. Hersey

Science Bulletin

In an examination of recent texts in general science one is impressed by the place given to a discussion and study of air in its various phases and applications. The expression "air minded" does not apply in this connection, but perhaps it holds true that a great amount of interest is always developed in pupils whenever we introduce the subject.

A Classified Bibliography Of References For General Agriculture, Winfield Scott

Science Bulletin

Most teachers are exceedingly busy with their regular duties in the school. This leaves but little time to look up references or for that matter to plan the work once the school year has begun. Their success is largely determined by the preparation which has been made before the school year opens. The following references have been prepared for these busy teachers who would like to enrich their courses in agriculture, but who do not have time to study or select references.

Exhibits As An Aid In Teaching, O. B. Read

Science Bulletin

Complaint is often made that science subjects are difficult to teach. Many feel they are so abstract that there is nothing tangible with which to start. Since most of our industrial products are now very closely controlled by physical principles and chemical processes, it ought not to be difficult in the study of these subjects to arouse interest by calling attention to their uses in the industrial process.

Living Material In The Laboratory, O. R. Clark

Science Bulletin

Living plants and animals serve as valuable aids in stimulating interest in the biology course and, during that part of the year when field trips are impossible, provide material for the study of habits and the relation of organisms to their environment. Laboratory conditions are of course artificial but they should be made as nearly natural as it is possible to make them.

Teaching The History Of Science

Science Bulletin

Science has contributed more to our comfort, well being, and happiness than any other branch of knowledge. The other branches of knowledge are now taking the scientific method for the solving of their problems. Is it not important that science teachers should find some place in their teaching to teach some of the history of the development of science?

Winter Bird Study

Heat, L. Begeman

Science Bulletin

The subject of heat as discussed in most texts in general science involves only the most elementary concepts as regards its theory. As a rule the following topics are the leading ones: - sources of heat, thermometry, methods of heat transmission, effect of heat, and a number of the common everyday practical applications of heat.

Insects And Man, Roy L. Abbott

Science Bulletin

Biologically speaking, insects may be called a highly successful group, and much of this success is due to their adaptability to the conditions of their environment. They are found everywhere, and eat almost everything. All of the large groups of insects are world-wide in their distribution, though the most widely distributed are the beetles.

The Simple Machines, L. Begeman

Science Bulletin

With reference to a pulley system, the work equation is clearly discerned in its practical operation. In presenting the pulley, the writer uses a rectangular frame about two feet high and three feet wide. A number of hooks are screwed into the top cross piece of the frame. With such a device a number of different pulley combinations can be shown at one time.

Science Minded, Harold E. Murphy

Science Bulletin

When we are trying to be "air minded " and "peace minded" why not go a little further and be 'science minded"? The aeronautic field has as its champion, Colonel Lindberg; the Peace Federation has as its champion, Ishbell McDonald; but where is the youthful champion of the field of chemical science? In this day of scientific advancement, a champion is surely needed to bring t h e achievement of chemical science to the people. Someone has said, "Science is the Creator's chest of tools. Human progress is man's learning to use these tools."

Some Suggestions Concerning The Management Of The Laying Flock In Winter, Winfield Scott

The Simple Machines, L. Begeman

Science Bulletin

In the discussion of simple machines it is best to begin with the lever and the wheel and axle. Both of these simple machines give us a practical illustration of the principle of moments. The lever is the simpler and clearer illustration and usually presents little difficulty to a student body. The wheel and axle is a device which can be considered to be a continuously acting lever in which the radius of the wheel is the force or effort arm and the radius of the axle is the resistance arm.
