Molecular Forces, L. Begeman May 1929

Molecular Forces, L. Begeman

Science Bulletin

The three states of matter denoted as solids, liquids and gases are different phenomena of matter arising from a change in the intensity of molecular attractions.


New-Type Tests In Agriculture, Winfield Scott May 1929

New-Type Tests In Agriculture, Winfield Scott

Science Bulletin

Modern methods of testing a pupil's knowledge have been applied successfully in the teaching of agriculture. The writer submits a few sample question sets as illustrative material.


Collecting Specimens At Night, Roy L. Abbott May 1929

Collecting Specimens At Night, Roy L. Abbott

Science Bulletin

Many teachers of biology don’t realize how much valuable biological material may be collected after dark. In fact, certain specimens, as grasshoppers, earthworms, and various species of amphibia, are most easily captured then.


Crystallization, L. Begeman May 1929

Crystallization, L. Begeman

Science Bulletin

One of the most interesting molecular phenomena in nature is known as crystallization. It is brought about in the arts of man and in nature by three methods. When a chemical salt, such as table salt, is dissolved in water and allowed to stand in a shallow dish until it dries, it will be observed that the solid residue appears as crystals. Those from common table salt will be cubical in form. However, every different salt will yield its own distinctly shaped crystal.


Editorial May 1929

Editorial

Science Bulletin

Nothing will more largely contribute to the teacher's peace of mind or to the pupils' efficiency than proper foresight for the fall. A two or three day incarceration in your empty and silent laboratory and classroom some time between the closing and reopening of school should represent a good investment. During this voluntary exile, put to yourself a few questions and motorize the answers.


Capillarity, L. Begeman May 1929

Capillarity, L. Begeman

Science Bulletin

One of the best practical illustrations of the effect of surface tension is found in capillarity. For this topic the instructor will do well to base his teaching upon surface tension. It is this force that raises the water in a clean glass capillary tube and that depresses the mercury in such a tube.
