General Science, L. Begeman
General Science, L. Begeman
Science Bulletin
What is General Science? It is wholly an environmental study-not merely one's natural environment but more particularly his man-made environment. In this day and age three-fourths of a man's existence is spent in an environment of invention whether it be in the home or on the street.

The Plight Of The Biologist: Editorial
The Plight Of The Biologist: Editorial
Science Bulletin
This is indeed an age of science! For the past three hundred years, man has wooed the Goddess of Nature and so ardent has been his wooing, like Sampson of old, she has finally told him her secrets of power.
The Story Of Steve, And Others, Roy L. Abbott
The Story Of Steve, And Others, Roy L. Abbott
Science Bulletin
Steve was a Leopard frog. I say "was" because he long since vanished into the maw of a snapping turtle, and would straightway have been transformed into a part of that twenty-pound bundle of ferocity, had not said turtle been thrown into a furnace by an irate janitor who was fond of Steve but disliked the snapper. Hence, the end of Steve was the occasion for this story of frogs in general and Steve in particular.
Further Observations On The Golden Digger, Roy L. Abbott
Further Observations On The Golden Digger, Roy L. Abbott
Science Bulletin
In two previous numbers of this journal, I have already given some of the results of my studies on the habits, instincts, and intelligence of the Golden Digger wasp. During the past summer I have again studied this wasp, but will give here only a few observations, reserving the rest for a more extended paper.
The State Course Of Study: Chemistry, R. W. Getchell
The State Course Of Study: Chemistry, R. W. Getchell
Science Bulletin
The State Department of Public Instruction has recently completed a far-reaching and valuable contribution to the curriculums of our state system of schools. With the cooperation of many prominent educators of Iowa, courses of study for the grades and departmental courses for the High Schools have been carefully prepared and made available to all teachers. Among these outlines is one for chemistry teachers. According to policy, these course outlines are distributed gratis to the school and become the property of the district.
The Beehive As An Aid In Biology, Winfield Scott
The Beehive As An Aid In Biology, Winfield Scott
Science Bulletin
The honey bee never fails to generate interest. She calls forth the instinct of curiosity in the daring and fear in the timid. She challenges the courageous only to teach him caution. She challenges the timid and develops confidence. To those who like to study instinct in relation to environment, she presents countless problems.

Torrid, Temperate And Frigid, Misleading Terms In Geography, Alison E. Aitchison
Torrid, Temperate And Frigid, Misleading Terms In Geography, Alison E. Aitchison
Science Bulletin
In the March, 1930, issue of the Science Bulletin there was published an article under the caption “Misleading Terms in Geography''. After a discussion of certain terms which had found their way into the science before the days of extended and careful exploration the authors presented an investigation which was being carried on and asked the help of Bulletin readers in furthering it. Since many of the readers of the Bulletin are new and many more have probably forgotten the article it might be well to re-state the problem.

Science In Seventh And Eighth Grades, Mabel Gauger
Science In Seventh And Eighth Grades, Mabel Gauger
Science Bulletin
Much value is obtained from clippings and pictures brought by the pupils and explained by them to the other members of the class. The article is discussed and then put on the bulletin board for two weeks where all may read it. Five or ten minutes of each class period are given over to "News", whether it be of the type above mentioned, or some personal experience, discovery or question along the line of the unit being studied.
Life In The Biology Laboratory, E. G. Brockman
Life In The Biology Laboratory, E. G. Brockman
Science Bulletin
Shortly before our class in 10th grade biology was formed, I started preparing a balanced aquarium for the laboratory. In it we have about a dozen small gold fish, several snails, two tad-poles, and a good growth of moss. This aquarium has provided us a great deal of pleasure, as well as many illustrations of life itself.
The Magnetic Effect Of An Electric Current, L. Begeman
The Magnetic Effect Of An Electric Current, L. Begeman
Science Bulletin
From a practical point of view, the magnetic property of an electric current is of great value to man. It is this property that is utilized in the dynamo for the generation of large currents of electricity. It is also this property that enables man to utilize the driving power of the electric motor in the manufacturing industries.

Stimulants, H. Earl Rath
Stimulants, H. Earl Rath
Science Bulletin
The state law requires the teaching of the effects of narcotics and stimulants. Most teachers would be glad to comply with the law if they were certain that they could present reliable information. The difficulty in the past has been that most of this information available was merely propaganda and not based on scientific fact. The tobacco companies have always been able to secure statements from people of prominence who were tobacco users to the effect that tobacco not only did them no harm but actually proved of value. Their statements were not based on scientific evidence, and many of …

Science Bulletin
The new state course of study in general science was reviewed by Dr. Lantz in the April number of the Science Bulletin. The state course in physics, also just recently published by the State Department of Public Instruction, is likewise an important contribution to science teaching.

The Project In High School Science, Don D. Pettit
The Project In High School Science, Don D. Pettit
Science Bulletin
The use of the project in teaching the high school sciences is one of the major means of holding the interest of those who are taking the course chiefly because of requirements for graduation or college entrance. No doubt it would be an excellent means of presenting an entire year's work but would require a good deal of the teacher's time to develop such a course of study. This obstacle might well be overcome by gradually introducing the project year by year until the complete field was covered.
The State High School Course In General Science, C. W. Lantz
The State High School Course In General Science, C. W. Lantz
Science Bulletin
The course of study in general science for high schools issued by the State Department of Public Instruction has recently come from the press. The course is divided into fifteen units. Of these, eight are devoted primarily to physical and chemical facts; five are of a biological nature; and two deal with facts of astronomy and meteorology. The authors, however, have succeeded well in constructing a course in general science and have not merely put together unrelated parts of physics, chemistry, biology, and astronomy.
Effects Of An Electric Current, L. Begeman
Effects Of An Electric Current, L. Begeman
Science Bulletin
In two preceding articles, the writer has discussed the nature of an electric current and the three practical ways of producing it. The question now naturally follows: What are the uses of an electric current? Speaking generally, we use an electric current for lighting, for heating, for chemical work, for mechanical work, and for therapeutic or physiological treatments of various human ailments.
Weather Lore, E. J. Cable
Weather Lore, E. J. Cable
Science Bulletin
Are you one of the great throng that believe in superstition? Do you look with gloom and dismay upon future weather if, on ground-hog clay, this harmless animal should be so unfortunate as to see his noon day shadow and then hie himself to mother earth for another six weeks I period? Do you think it makes any difference if you plant y our garden seeds in the light of the moon or lay shingles in the dark of the moon!
Cell Secrets, R. W. Getchell
Cell Secrets, R. W. Getchell
Science Bulletin
This is a true picture of one class of cell products, the enzymes; and it represents with considerable accuracy two other products of the cell, the vitamines and the hormones. These three wonderful agencies challenge our interest and provoke a tremendous amount of research at present because they are so far-reaching in their effects and because they hugely baffle any attempt to isolate or identify them.
