It Is Now Time To Commence To Keep Your Bird Records

Science Bulletin

It is now time to commence to keep your bird records in order to follow the spring migration of birds.

Science Reading

Science Bulletin

One of the purposes of science teaching in the high school should be to train the pupils to appreciate and to read intelligently and critically the articles of scientific interest that appear in the public press.

Newton's Laws Of Motion, L. Begeman

Science Bulletin

In the study of Newton's Laws of Motion, it is more important to understand the concepts they embody than to be able to repeat them verbatim. Too frequently, in the teaching of high school physics, memory work is allowed to take the place of concrete information. This is particularly true with reference to these basic mechanical concepts of the physical universe known as Newton's Laws of Motion.

Health And Cleanliness, H. Earl Rath

Science Bulletin

A short time ago there was presented in the columns of this paper an article dealing with the methods of motivating a health program. This article dealt with the methods of gaining an interest in the subject of health. Once having gained this interest a program of education must be brought forward. Such a program may not be elaborate, in fact probably should not be. It is the opinion of the writer that most programs of health attempt to cover too wide a field and do not leave sufficient definite impressions.

In addition to the simple experiments already suggested attention is called to others which will show the common constituents of the air.

Household Insects, Roy L. Abbott

Science Bulletin

It was said above (see November Bulletin) that practically every animal is attacked by one or more kinds of insects. Man constitutes no exception to this statement, and it is my purpose in this article to deal with a few of the insects commonly found in or around our homes. Perhaps the most familiar of all household insects is the housefly.

Motion, L. Begeman

Science Bulletin

Motion is a general property of matter. There is no rest in the absolute sense. An object at rest with reference to the earth 's surface is in rapid motion with reference to the earth's axis of rotation just as a person may be at rest in a Pullman car and at the same time be in rapid motion with reference to the ground. All divisions of matter, - masses, molecules, atoms, protons, and electrons are moving relatively all of the time.

Astronomy, E. J. Cable

Science Bulletin

In the field of general science, astronomy offers projects for practical as well as very useful knowledge. One of the greatest values is its appeal to the intellect. Astronomy attempts to unravel the secrets of nature, not only on our planet, but also in the vastness of space around us that is within reach of man's powerful instruments. It acquaints man with what is going on around him as well as with what is happening in regions far removed from everyday experiences and personal contacts. Astronomy tries to make man feel "comfortable" and at "home" in his universe.

The Air We Breathe, S. F. Hersey

Science Bulletin

In an examination of recent texts in general science one is impressed by the place given to a discussion and study of air in its various phases and applications. The expression "air minded" does not apply in this connection, but perhaps it holds true that a great amount of interest is always developed in pupils whenever we introduce the subject.

Most teachers are exceedingly busy with their regular duties in the school. This leaves but little time to look up references or for that matter to plan the work once the school year has begun. Their success is largely determined by the preparation which has been made before the school year opens. The following references have been prepared for these busy teachers who would like to enrich their courses in agriculture, but who do not have time to study or select references.

Exhibits As An Aid In Teaching, O. B. Read

Science Bulletin

Complaint is often made that science subjects are difficult to teach. Many feel they are so abstract that there is nothing tangible with which to start. Since most of our industrial products are now very closely controlled by physical principles and chemical processes, it ought not to be difficult in the study of these subjects to arouse interest by calling attention to their uses in the industrial process.
