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.


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.


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.


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.


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.

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.

Improved Methods In Science Teaching, Louise Hearst Feb 1929

Improved Methods In Science Teaching, Louise Hearst

Science Bulletin

Pasteur has said that "in our century science is the soul of the prosperity of nations and the living source of all progress." Teachers of this important branch of knowledge, then, should carefully consider the methods of instruction in the science departments of our secondary schools. As these methods vary considerably, no general criticism of them will be attempted here. However there are certain fundamentals that merit attention, and in this paper we will examine three of them.


Plant Study In General Science, C. W. Lantz Feb 1929

Plant Study In General Science, C. W. Lantz

Science Bulletin

The general science course in most high schools is conspicuous by its lack of plant study. Usually there is a brief study of micro-organisms, but the higher plant is often completely ignored. Why is this? Is it because the subject matter of plant study is of a special nature and is not of general importance? Ts it because plant study is not of interest and cannot be adapted to beginners in high school? Perchance it is because most of our general science textbooks have been written by physicists and chemists.

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.


Simple Experiments To Show Atmospheric Pressure, L. Begeman Jan 1929

Simple Experiments To Show Atmospheric Pressure, L. Begeman

Science Bulletin

The teacher of general science in a small high school often lacks complete laboratory equipment, yet many experiments can be conducted, with simple, inexpensive, and readily available material. For the demonstration of atmospheric pressure, try the following experiments.


Cockroaches For Laboratory Study, Roy L. Abbott Jan 1929

Cockroaches For Laboratory Study, Roy L. Abbott

Science Bulletin

Teachers of high school biology are often handicapped by a lack of living material. This is particularly true in the teaching of insects. Most texts in biology use the grasshopper as a type of insect, largely, I suppose, because of its familiarity to the average pupil.


Laboratory Upkeep, R. W. Getchell Jan 1929

Laboratory Upkeep, R. W. Getchell

Science Bulletin

The article last month dealt with reagent bottles. Another problem is met in the proper care of iron ware - the special target of the corrosive laboratory fumes. To supply the pupil with rusty, oxide encrusted metal equipment is to encourage careless, slovenly work. An annual "paint day" is essential.
