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.

Butterflies Taste With Their Legs

Science Bulletin

Miss Almeda Anderson, of the University of Minnesota, has discovered that Monarch butterflies taste with their legs.

Text Books In Physics

Science Bulletin

In the November number of the Science Bulletin a list of text books on General Science was given, with a brief statement concerning each. Below is given a list of high school texts on Physics.

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.

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.

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.

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.

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.

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.

Practical Methods Of Producing A Current Of Electricity, L. Begeman

Science Bulletin

Currents of electricity as utilized by the electrical engineer fall naturally into three classes, viz.: those produced by chemical action in batteries; those produced by magnetic induction in dynamos; and those produced by the direct action of heat in thermo-cells.

Question Box, W. H. Kadesch

Science Bulletin

What is Huyghens's theory of the transmission of light? What objections to this theory have been advanced? How have these been met?

Scrap Books In Science Teaching, James Kercheval

Science Bulletin

Scrapbooks may become a very valuable connecting link between science in the classroom and science in everyday use.

The Migration Of Birds: Part Ii, O. R. Clark

Science Bulletin

The migration routes are without doubt the result of a long evolution and it is thought that birds may be gradually changing their routes today. A number of factors are involved in determining the routes which different species follow.

A Field Trip In General Science, Russia Harris

Science Bulletin

Yesterday my General Science classes visited the water plant to learn how Iowa City secures and prepares its water supply. In preparation for this I made a preliminary visit to the plant and prepared a skeleton outline, as given below, of the information to be gained.

Science In The High School Curriculum, C. L. Jackson

Science Bulletin

“What sciences should be offered in a consolidated high school?” “Our high school school enrollment is about three hundred. What sciences should we include in our course of study?”

For several reasons no dogmatic statement will be made in answer to such questions, but it is hoped that we may be able to offer some suggestions which may help the individual superintendent or principal in deciding the questions for himself.

Makers Of Science, S. F. Hersey

Science Bulletin

In the November number of the Science Bulletin the suggestion was made with reference to science clubs that "Human interest biographies of noted scientists'' would be interesting and helpful. This idea has appealed to the writer as a sound one and has inspired the writing of the present article.

The Migration Of Birds: Part I, O. R. Clark

Science Bulletin

Among the most characteristic and familiar activities of our birds are their regular seasonal movements between their winter homes and their summer nesting sites.

The Planetesimal Hypothesis, E. J. Cable

Science Bulletin

In a former article the writer called attention to the fact that the La Placian hypothesis has been abandoned by scientists because of the serious astronomical, biological, dynamical, and geological difficulties encountered. The Planetesimal or Accretion hypothesis, which has superseded it, is the gift of Doctor T. C. Chamberlin, formerly head of the Department of Geology at the University of Chicago and Director of the United States Geological Survey.

Plant Disease Control, C. W. Lantz

Science Bulletin

In the November issue of the Bulletin some idea of the crop losses due to plant diseases was given. Obviously the farmer should be concerned in preventing these losses if he is to profit most from his labor. The control of plant disease lies in prevention rather than cure. In most cases, the individual plant is not of sufficient value to warrant an attempt to cure it. The exceptions would be in those cases where a valuable individual plant such as a shade tree becomes diseased and it would be desirable to save it.
