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.

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.

Suggestions For Health Classes, Belva L. Swalwell

a. If one has been exposed to smallpox should he be vaccinated at once? Smallpox, I; Smallpox, III.

b. What factors should one look for in buying a new pair of shoes? Shoes, I.

c. A child has been bitten by a dog which is suspected of being mad. How can it be determined H the dog really has rabies? What should be done with the dog? What should be done with the child? Rabies, III; Rules and Regulations of the State Board of Health, III.

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?
