The Physiology Of Physical Condition, H. Earl Rath

Science Bulletin

Some men willfully break training rules because they think more of their own personal pleasure than they do of the success of the team or their own success as athletes. The treatment, if any, for this sort of individual must be mental. Many boys fail to observe training rules because they do not know what good physical condition is, or because they do not see the necessity of doing certain things in order to obtain it. It is for this latter group that this article is written, with the hope that it will make easier the grind of training by …

The Questionnaire

Science Bulletin

The request for suggestions which was sent out with the September number of the Bulletin brought a flood of unexpected magnitude. The editor was quite inundated, and even now has only partially emerged. But it was a welcome flood, which showed clearly what the science teachers of Iowa wish in such a bulletin-wish individually. Collectively they are not in all respects agreed.

Environment As A Factor In The Growth And Distribution Of Plants, O. R. Clark

Science Bulletin

The form and appearance of plants and the activities which they carry on are due in large part to the inherited characteristics of their ancestors. The influence which heredity exerts should be clearly and forcefully presented to students. At the same time the expression of the hereditary traits may be greatly modified by the conditions under which! the plants grow.

Instinct Or Intelligence In The Great Golden Digger, Roy L. Abbott

Science Bulletin

''To know everything and to know nothing according as it acts under normal or exceptional conditions: that is the strange antithesis presented by the insect race.” So said that profound student of insects, Fabre, after an immense amount of experimentation.

Question Box, R. W. Getchell, E. J. Cable, O. B. Read, W. H. Kadesch

Science Bulletin

How can breakage fees be best handled in connection with the high school laboratory sciences?

Will you describe the method followed by the weather bureau in weather forecasting?

When you blow burns the better. or fan a camp fire it When you blow a candle it goes out. What is the reason for the difference?

Should static electricity be continued as a part of the high school physics course?

Outline For Elementary Physics, L. Begeman

Science Bulletin

In the September number of the Science Bulletin will be found the outlines for the subjects of Mechanics and Heat. We submit in this number the remaining outlines of the principal subjects that should be presented in a high school course in Physics.

The Romance Of The Great Golden Digger, Roy L. Abbott

Science Bulletin

Every year for the last fifteen years (and perhaps for much longer) a number of digger wasps have made their nests in the hard-packed sanely soil between Professor Fullerton's room and the heating plant on the campus of the Iowa State Teachers College.

Outline For Elementary Physics, L. Begeman

Science Bulletin

The outline below is submitted with the hope that it may be helpful particularly to the teacher of physics in the smaller high schools. The outline is arranged in the form of group projects and in the order which the writer thinks is best for good teaching results. The apparatus listed can be purchased in one form or another from such supply houses as the Central Scientific Co. or the Welch Apparatus Co. of Chicago, Ill.

Question Box

Science Bulletin

Questions submitted before the end of the month will be answered in the next number of the Bulletin.

General Science: Astronomy, E. J. Cable

Science Bulletin

General science is, as the name suggests, a study of the practical applications of the physical and natural sciences. To be a good teacher of the subject one should have a working understanding of the fundamental principles of physics, chemistry, biology, physiography, astronomy and climatology. General science, when taught as such in the grades or junior high school, should aid boys and girls to interpret, in an intelligent and meaningful way, the application of these principles to everyday life.

Natural Science: Seed Corn, Winfield Scott

Science Bulletin

Again we come to the annual problem of seed corn and show corn. In the first place good seed corn is important to all of us because missing hills and barren stalks mean wasted labor, wasted time, and wasted land. Since human labor and time are our most valuable assets why waste them through useless endeavor by planting corn which will not grow nor yield?

We, The Jury, R. W. Getchell

Science Bulletin

Iowa high schools may justly be proud of their chemistry courses and of their chemistry teachers. The state ranks low in the number of schools offering this science but high in the quality of its teaching staff. One sure criterion of instructional efficiency is growth - a growth based upon the frank recognition of mistakes and intelligent effort to correct them.

Planning The Year's Work

Science Bulletin

One of the important things for the science teacher to do at this season is to lay definite plans for the work of the semester or year. One way to do this is to entrust everything to the text book.

Insects And Man, Roy L. Abbott

Science Bulletin

Because of their relationship to dangerous human parasites, insects have been responsible for the death of more people than all other animals put together. Confirmation of this astounding statement can be seen in the close relationship between houseflies and typhoid fever, between rat fleas and plague, tsetse flies and sleeping sickness, and that between mosquitoes and yellow fever and malaria.

Care Of Laboratory Equipment, Harold E. Murphy

Science Bulletin

"We have good equipment, but no place to keep it arranged in order so that we have quick access to it." The above statement describes the condition under which some high school departments operate. A condition of this kind places extra work upon the teacher and uses valuable time that is needed in class room instruction.

The Conservation Of Wild Flowers, O. R. Clark

Science Bulletin

On almost any warm spring day when the first woodland flowers have made their appearance, it is a very common sight to see parties of children, and many older people as well, scouring the woods in search of wild flowers.

Joseph Henry, W. H. Kadesch

Science Bulletin

Have you ever asked your pupils the question, what American has contributed most to the development of electrical science? Very likely a great majority would answer without hesitation, Edison, the inventor of the incandescent light. Some might answer, Bell, the inventor of the telephone. A few, the radio fans, might say De Forest, the inventor of the three electrode tube. An occasional one might even answer Franklin, the first great American scientist, who drew electricity from the clouds, and showed that lightning and the "electric fluid" are the same. Not one, I am sure, would ever mention Joseph Henry.

This Number Of Science Bulletin Is The Last Number For The School Year 1929-30.

Science Bulletin

This number of Science Bulletin is the last number for the school year 1929-30. We hope that we have been able to give the high school teachers of Iowa material that they have found interesting and helpful. The responses that we have had from you lead us to believe that we have been able in some measure to do this.

At The Close Of The School Year You Will Be Making Your Plans For The Summer.

Science Bulletin

At the close of the school year, you will be making your plans for the summer. Teachers have an excellent opportunity during the summer to advance themselves professionally by study and travel. Most of our universities and colleges have summer schools planned especially for teachers and I know of no better way to spend at least a part of your summer than at one of these.

Chemical Lecture Experiments, R. W. Getchell

Science Bulletin

Lecture experiments demand more time, require higher technical skill, and afford greater pupil interest than any other phase of chemistry teaching. As a corollary, we may add that they are most neglected, but if you name the teachers who are noted for their interesting, instructive, and skillful classroom demonstrations, you are calling the roll of chemistry teachers of the first rank.
