Introducing The Biology Course In The Classroom, Roy L. Abbott
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
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
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
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
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
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
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
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
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.
Plant Study In General Science, C. W. Lantz
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.

Editorial
Science Bulletin
Scientific standardization, both of materials and labor, is one of the most outstanding developments of the last decade in the industrial world. Apparently the last group of people to apply this method to their own problems are the very ones who originated the principle. We refer to the scientists and especially to the teachers of science. Our study of the science course offered in secondary schools and our experience with college students in science emphasize the entire lack of uniformity among high school science courses.
Improved Methods In Science Teaching, Louise Hearst
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.
Laboratory Work In Poultry, H. Earl Rath
Laboratory Work In Poultry, H. Earl Rath
Science Bulletin
It is probable that the winter feeding, housing and management problems of poultry have been taken up in class before this time. If not, the alert agricultural instructor can develop some very practical laboratory work by conducting a survey in the community of the conditions under which poultry is kept, and then comparing the results obtained from flocks cared for under varying conditions.
Atmospheric Pressure, L. Begeman
Atmospheric Pressure, L. Begeman
Science Bulletin
An account of the experiment reached Paris the next year and came to the notice of Pascal. He could not try the experiment until 1646 when glass tubes were available to him. Pascal reasoned that if the atmosphere supported the mercury column, the height of the column should be lessened when the apparatus was carried to a high altitude.
Simple Experiments To Show Atmospheric Pressure, L. Begeman
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.
The Teaching Of Physiography, E. J. Cable
The Teaching Of Physiography, E. J. Cable
Science Bulletin
It is quite unfortunate that a subject as valuable as physiography finds such a small patronage among our high school pupils. This is probably due partly to the fact that there is still a lack of agreement among teachers as to the content or classification of the subject. In some high schools physiography is required of all freshmen. Often it goes under the title of "general science" or "modern geography."

Cockroaches For Laboratory Study, Roy L. Abbott
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.
Editorial
Science Bulletin
We enjoyed a visit the other day with the representative of a company which supplies files for government publications. This reminds us of how essential to good teaching is supplementary material. It both instructs and offers variety. Too often, in the mind of the pupil, the words schoolroom and monotony are synonyms.
Atmospheric Pressure, L. Begeman
Atmospheric Pressure, L. Begeman
Science Bulletin
Having learned the meaning of "pressure" from the study of hydrostatics, the pupil is easily led to understand the striking phenomena of atmospheric pressure. He should readily appreciate that the term refers to the gravity pressure of the atmosphere.
Winter Study Of Trees, O. R. Clark
Winter Study Of Trees, O. R. Clark
Science Bulletin
One often hears the idea expressed that there is little to be done during the winter months in the way of field or laboratory studies of trees. In reality there is a wealth of material available and the following suggestions are offered in the hope that they will be helpful in calling attention to the possibilities of winter tree study.
Hydrostatics, L. Begeman
Hydrostatics, L. Begeman
Science Bulletin
The classroom apparatus necessary for an effective, interesting presentation of hydrostatics includes: pressure tubes, manometer tubes, pressure syringe, Pascal's vases and equilibrium tubes. All of these are listed in the apparatus catalogs found in every high school.

Laboratory Upkeep, R. W. Getchell
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.
An Experiment In Hydrostatics, L. Begeman
An Experiment In Hydrostatics, L. Begeman
Science Bulletin
Individual laboratory work in hydrostatics is not very essential if the teacher is properly equipped for classroom demonstration. However, it would be interesting and profitable in communities where gas is sup- plied to the laboratory, to have the student measure the gas pressure by means of a water column.
