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

Science Bulletin

What birds are to be found in your vicinity during the winter months? We would like to have observers from different parts of Iowa report to us a list of the winter birds they find, giving us the date of observation and the locality. We will be glad to publish your reports.

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

Science Bulletin

I. Community Poultry Survey. The following outline will serve as a basis for the survey. After the completion of the survey make a study of data and draw conclusions as to cause of the failure of some flocks and the success of others.

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.

Our Weather, E. J. Cable

Science Bulletin

There is probably no subject which so fully occupies our attention or is of more significance to us than is the weather. It is also probably true that there is no subject about which the average individua l knows less. Superstition and ignorance run riot in the minds of those who know little about the cause of our weather. To the end that a little light may be shed in darkened minds where superstition plays havoc, the writer ventures this short article. The suggestion may give the teacher of general science a new urge to carry on along this line …

Nature Notes

Science Bulletin

There are many fallacies concerning nature that are commonly believed by many people. It is the duty of science to correct these fallacies and superstitions. Below are listed a few very common ones.

A Health Program, H. Earl Rath

Science Bulletin

Now that school is well started, suppose we stop and make an inventory of our health to see how well we are equipped to carry forward a successful year.

Mechanics Of Solids, L. Begeman

Science Bulletin

According to the traditional arrangement of subject matter in textbooks on high school physics, it is customary to introduce the treatment of mechanics of so-lids by beginning with the subject of motion, force, and Newton's laws of motion. This at once leads the immature student into a labyrinth of abstract conceptions that is generally disheartening. It would show better judgment on the part of the teacher to begin the subject of mechanics with material that is more concrete to the student and which is continually before him in his environment.

Last Year Science Bulletin Made Its Appearance

Science Bulletin

Last year Science Bulletin made its appearance. Your response was such that we feel encouraged to continue, and after one year's experience we should be able to make the bulletin more of a real service bulletin to the teachers in the field. We invite your suggestions and criticisms. While we all like commendations, yet we realize that unfavorable criticism is sometimes most helpful. Let us have your "brickbats" as well as your "bouquets."

The Use Of The Football Squad As Laboratory Material For Physiology, H. Earl Rath

Science Bulletin

As school is getting under way for the new school year, the teacher of physiology or hygiene is probably busily engaged in looking over the laboratory equipment to see what can be found to demonstrate the functioning of the human body. In all probability many instructors will decide that there is not enough material on hand to justify an attempt at demonstrations, while regular laboratory work will be considered out of the question.

Suggestive Procedure In Presenting A Course In Profitable Corn Production, Winfield Scott

Science Bulletin

Community Survey

1. How many acres of corn are grown on the home farm? 2. How many acres of corn grown on farms not represented in class? (This answer can be secured by assigning to each pupil a definite number of farms which are not represented in class) 3. What is the yield per acre of (a) the home farm? (b) the assigned farm? 4. What is the total yield on (a) the home farm? (b) the assigned farm?

Insects And Man, Roy L. Abbott

Science Bulletin

Mrs. Jiggs, in the cartoon, "Bringing up Father," frequently calls her husband an insect. This is a flagrant misuse of the term as an insect never has fewer nor more than six legs. It may be wingless as are the bedbugs, two winged as are all flies, or four winged as the grasshoppers, but no normal insect ever has more or less than six legs and by this one positive character you may know them.

Has Commercial Geography Been Left On Your Doorstep, Alison E. Aitchison

Science Bulletin

If one of the chief aims of a teacher is to induce her pupils to know and love a subject which she herself knows and loves, then commercial geography in many an Iowa high school is in a sorry plight. In cases too numerous to cite, the home econ- omics teacher, the mathematics teacher, the physics teacher, the English teacher, - in fact anyone who is so unfortunate as to have one period of the day unfilled by his or her own special subject, - Is likely to have that foundling child, commercial geography, left on the doorstep.

Anniversaries Of Science, O. B. Read

Science Bulletin

To know biography is to have a knowledge of history. By a study of the biography of our scientists we may secure a very satisfactory knowledge of the development of most scientific discoveries. The life and works of many of the noted scientists present a story of adventure and achievement which to the young may become a great inspiration.
