Anniversaries Of Science, O. B. Read May 1929

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.


Molecular Forces, L. Begeman May 1929

Molecular Forces, L. Begeman

Science Bulletin

The three states of matter denoted as solids, liquids and gases are different phenomena of matter arising from a change in the intensity of molecular attractions.


Teachers' Courses May 1929

Teachers' Courses

Science Bulletin

Special courses for teachers of science are offered at this college.


Editorial May 1929

Editorial

Science Bulletin

Nothing will more largely contribute to the teacher's peace of mind or to the pupils' efficiency than proper foresight for the fall. A two or three day incarceration in your empty and silent laboratory and classroom some time between the closing and reopening of school should represent a good investment. During this voluntary exile, put to yourself a few questions and motorize the answers.


Has Commercial Geography Been Left On Your Doorstep, Alison E. Aitchison May 1929

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.


Capillarity, L. Begeman May 1929

Capillarity, L. Begeman

Science Bulletin

One of the best practical illustrations of the effect of surface tension is found in capillarity. For this topic the instructor will do well to base his teaching upon surface tension. It is this force that raises the water in a clean glass capillary tube and that depresses the mercury in such a tube.


New-Type Tests In Agriculture, Winfield Scott May 1929

New-Type Tests In Agriculture, Winfield Scott

Science Bulletin

Modern methods of testing a pupil's knowledge have been applied successfully in the teaching of agriculture. The writer submits a few sample question sets as illustrative material.


Crystallization, L. Begeman May 1929

Crystallization, L. Begeman

Science Bulletin

One of the most interesting molecular phenomena in nature is known as crystallization. It is brought about in the arts of man and in nature by three methods. When a chemical salt, such as table salt, is dissolved in water and allowed to stand in a shallow dish until it dries, it will be observed that the solid residue appears as crystals. Those from common table salt will be cubical in form. However, every different salt will yield its own distinctly shaped crystal.


Collecting Specimens At Night, Roy L. Abbott May 1929

Collecting Specimens At Night, Roy L. Abbott

Science Bulletin

Many teachers of biology don’t realize how much valuable biological material may be collected after dark. In fact, certain specimens, as grasshoppers, earthworms, and various species of amphibia, are most easily captured then.

Presenting The Problems Of Feeding, H. Earl Rath Apr 1929

Presenting The Problems Of Feeding, H. Earl Rath

Science Bulletin

It has been the experience of the author that the teaching of feeding taxes the ingenuity of the agricultural instructor more than most other agricultural topics. The mere statement of principles without application or proof offers little of permanent value to the pupil. On the other hand, an attempt to pursue all, or even a small part, of the mass of data necessary to prove even a single principle, leaves the student groggy and confused. Neither is there time allowed in most courses for such procedure.

A Plea For The Boys, Belva L. Swalwell Apr 1929

A Plea For The Boys, Belva L. Swalwell

Science Bulletin

Have you ever raised the question why high school boys are not allowed, as a rule, to take courses of the type of Personal Hygiene, Home and Community Hygiene, First Aid, Home Care of the Sick, Clothing, Foods, and the like - courses now open almost exclusively to girls?


Static Electricity, S. F. Hersey Apr 1929

Static Electricity, S. F. Hersey

Science Bulletin

There is ample evidence that many electrical phenomena were observed in early times. Thales, of Greece, about 600 B.C., observed that amber when vigorously rubbed would attract light bodies such as scraps of thin paper. When a piece of magnetic iron found in Asia Minor was seen to attract bits of iron it was suggested that the two phenomena might be identical, but early in the seventeenth century Dr. William Gilbert pointed out the difference and brought the words "magnetism" and "electricity" into use.


Molecular Forces, L. Begeman Apr 1929

Molecular Forces, L. Begeman

Science Bulletin

One of the characteristic properties of molecules assembled in masses is their attraction for one another. While it is customary to classify these attractions under two heads, cohesion and adhesion, it is well understood that there is in reality only one form of attraction.


Professional Growth, R. W. Getchell Apr 1929

Professional Growth, R. W. Getchell

Science Bulletin

The first class provides bits of scientific information which can be interspersed in class discussions. Such items will add interest to the class work and may indicate new and modern uses for chemical substances and appliances. They are found in such publications as Popular Science Monthly. The second class of articles are indispensable to good teaching.


Maps As Laboratory Material, E. J. Cable Apr 1929

Maps As Laboratory Material, E. J. Cable

Science Bulletin

If the study of physiography is to be made real, vital and practical, the classroom recitation should be ac- companied by some kind of well-planned laboratory work. The nature of the exercises should vary with the region in which the teacher works. Where it is possible to take classes out of doors to see the action of the various agents that are at work changing the surface of the earth, the classroom recitation is motivated in a way that cannot be secured from a mere verbal discussion. To make the study broader, the teacher should use the topographic map.

Introducing The Biology Course In The Classroom, Roy L. Abbott Mar 1929

Introducing The Biology Course In The Classroom, Roy L. Abbott

Science Bulletin

The success of any course in high school science often depends upon the interest aroused in it during the first days of its presentation. This interest is particularly easy to arouse in biology, chiefly, l suppose, because people are always interested in living things, or things that have been alive. Moreover, though he does not recognize it as such, nearly every pupil has considerable biological knowledge when he first comes to class, and it is this preliminary knowledge which can be made a strong entering wedge into his interest in the subject.


The Structure Of Matter, L. Begeman Mar 1929

The Structure Of Matter, L. Begeman

Science Bulletin

At the present time, physical science recognizes the following divisions of matter: masses, molecules, atoms, electrons and protons. Matter appeals to us directly in the form of masses. We can readily sense a mass of water, a mass of air or a mass of iron; but it is quite different with the other divisions of matter. Molecules are so small that it takes about seventy billion billion of them laid side by side to extend through the length of one inch.


Misconceptions Concerning Respiration, C. W. Lantz Mar 1929

Misconceptions Concerning Respiration, C. W. Lantz

Science Bulletin

The respiration of plants is misunderstood by a large majority of the students who enter our general botany classes in college. This misunderstanding is about as common among students who have had biological training in high school as among those who have not. I am also convinced that a very large majority of people, in general, not excluding college graduates, have the wrong conception of plant respiration. It seems that there must be something wrong with the teaching of this subject in our schools.


The Open Season For Teachers: An Editorial Mar 1929

The Open Season For Teachers: An Editorial

Science Bulletin

The next three months arc anxious ones among our teachers. Some are seeking advancement; others are hoping for re-election; and many are looking for their first school. Chance will play an important part in many cases. The "influential third party" will land positions for some. But for most applicants desirable qualifications will be the largest factor.


The Molecular Kinetic Theory, L. Begeman Mar 1929

The Molecular Kinetic Theory, L. Begeman

Science Bulletin

Every teacher of elementary physics should have a thorough understanding of the molecular kinetic theory of matter since it is so indispensable in the explanation of various phenomena in physical science. One might even divide contemporary elementary physics into three divisions, viz: mass physics, molecular physics and electronic physics.


Professional Growth, R. W. Getchell Mar 1929

Professional Growth, R. W. Getchell

Science Bulletin

An official in a small school system was discussing the requirements for a good teacher. "We prefer teachers," he said, "who will outgrow their position in our school." What greater challenge to professional growth could be offered to a teacher in service?


A Bird Study Plan, Winifred Gilbert Mar 1929

A Bird Study Plan, Winifred Gilbert

Science Bulletin

Examination of the subject matter of the most commonly used general science texts in Iowa shows the topic of "bird life" to be meager or wholly lacking.

Measuring The Stars, W. H. Kadesch Feb 1929

Measuring The Stars, W. H. Kadesch

Science Bulletin

Walking out on any clear and moonless night, one is thrilled at the sight of the seeming myriad of twinkling stars. To the artistically inclined, there is beauty and majesty, to the philosophically minded, food for speculation. ·where a r e these stars, what are they, whence come they, and ·whither do they go? Are they unchangeable through the aeons or do they progress through youth, maturity, old age, and finally into stellar death and oblivion? We ca n follow briefly only one or two of these speculations in these few short paragraphs.


Health Education, Belva L. Swalwell Feb 1929

Health Education, Belva L. Swalwell

Science Bulletin

Health work is so fundamental and so important that it cannot be left out of the high school course without seriously handicapping the individual, the state, and the nation. The recent state Iaws regarding health education place it, in effect, on a basis with other subjects. In other words, health education becomes one of the five major subjects running through the entire curriculum.
