The Farm Apple Orchard, Winfield Scott

Science Bulletin

Apples can be produced in Iowa on a profitable basis. They are a wholesome and a health producing food. They carry important minerals and vitamins. They are refreshing and palatable. Good apples will sell well. Good apples are those which possess quality, flavor uniformity, and which are free from disease and insects.

The More Scientific Tests, E. O. Finkenbinder

Science Bulletin

Scientific testing has contributed several things that may be recalled here with profit. First of these, it has given us much more reliable measures of pupils' abilities and accomplishments than by the "old-type" tests we were able to get. Reliability of a test refers to its accuracy in measuring. It means that if a written test shows a pupil to have a score of, say, 85, another pupil's written test of equal ability the same score, and it will give the same score whether marked by one teacher or any other.

Magnetism, L. Begeman

Science Bulletin

Interstellar space is characterized by the existence of three all pervading fields of force denoted respectively as gravitational, electric, and magnetic. Einstein in his general theory of relativity demonstrates mathematically that these three force fields are but different aspects of one universal field. To the average man, however, these three natural forces will always appear as separate distinct entities.

Newton's Laws Of Motion, L. Begeman

Science Bulletin

Newton's second law of motion states the relation between force and momentum. From this law we learn how to measure a force in terms of the momentum it creates in a unit of time or a second.

Suggestions For Health Classes, Belva L. Swalwell

Science Bulletin

The classes in high school conducted primarily for the purpose of imparting health knowledge which will lead to action are confronted with the problem of securing suitable material for supplementing the textbook work.

Winter Birds Of Iowa, O. R. Clark

Science Bulletin

The study of birds should certainly form an important unit of every course in high school biology. Furthermore, this study should be continued through the entire school year in order to secure the most desirable results. The fall is an excellent time to begin the study because the number of birds to be found is not so great as to ca use confusion and the students will be able to become familiar with the means of identification and the common recognition marks of many of our common birds.

Misleading Terms, Alison Aitchison, Marguerite Uttley

Science Bulletin

"Tradition is the enemy of progress." Dr. Julius Klein, Assistant Secretary of Commerce, advises young people to adopt this as their slogan if they wish to make for themselves successful pl aces in the business world. To train these embryo business men and women is the business of the public schools. Geography contributes to training for commerce more than any other science. Have geography teachers adopted the same slogan?

It Is Now Time To Commence To Keep Your Bird Records

Science Bulletin

It is now time to commence to keep your bird records in order to follow the spring migration of birds.

Science Reading

Science Bulletin

One of the purposes of science teaching in the high school should be to train the pupils to appreciate and to read intelligently and critically the articles of scientific interest that appear in the public press.

Newton's Laws Of Motion, L. Begeman

Science Bulletin

In the study of Newton's Laws of Motion, it is more important to understand the concepts they embody than to be able to repeat them verbatim. Too frequently, in the teaching of high school physics, memory work is allowed to take the place of concrete information. This is particularly true with reference to these basic mechanical concepts of the physical universe known as Newton's Laws of Motion.

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.

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

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.

Building The School Entertainment Day By Day: Cooperating Rather Than Competing In Play, Jennie Moore

All Faculty Scholarship for the College of Education and Professional Studies

To justify any school entertainment as an educational instrument, it must be rich in the learnings gained by day in the school through careful teacher guidance. How well does the average athletic meet express sound educational practice?

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.
