Simple Experiments To Show Atmospheric Pressure, L. Begeman

Science Bulletin

The teacher of general science in a small high school often lacks complete laboratory equipment, yet many experiments can be conducted, with simple, inexpensive, and readily available material. For the demonstration of atmospheric pressure, try the following experiments.

The Teaching Of Physiography, E. J. Cable

Science Bulletin

It is quite unfortunate that a subject as valuable as physiography finds such a small patronage among our high school pupils. This is probably due partly to the fact that there is still a lack of agreement among teachers as to the content or classification of the subject. In some high schools physiography is required of all freshmen. Often it goes under the title of "general science" or "modern geography."

Cockroaches For Laboratory Study, Roy L. Abbott

Science Bulletin

Teachers of high school biology are often handicapped by a lack of living material. This is particularly true in the teaching of insects. Most texts in biology use the grasshopper as a type of insect, largely, I suppose, because of its familiarity to the average pupil.

Winter Study Of Trees, O. R. Clark

Science Bulletin

One often hears the idea expressed that there is little to be done during the winter months in the way of field or laboratory studies of trees. In reality there is a wealth of material available and the following suggestions are offered in the hope that they will be helpful in calling attention to the possibilities of winter tree study.

Hydrostatics, L. Begeman

Science Bulletin

The classroom apparatus necessary for an effective, interesting presentation of hydrostatics includes: pressure tubes, manometer tubes, pressure syringe, Pascal's vases and equilibrium tubes. All of these are listed in the apparatus catalogs found in every high school.

Laboratory Upkeep, R. W. Getchell

Science Bulletin

The article last month dealt with reagent bottles. Another problem is met in the proper care of iron ware - the special target of the corrosive laboratory fumes. To supply the pupil with rusty, oxide encrusted metal equipment is to encourage careless, slovenly work. An annual "paint day" is essential.

Editorial

Science Bulletin

We enjoyed a visit the other day with the representative of a company which supplies files for government publications. This reminds us of how essential to good teaching is supplementary material. It both instructs and offers variety. Too often, in the mind of the pupil, the words schoolroom and monotony are synonyms.

An Experiment In Hydrostatics, L. Begeman

Science Bulletin

Individual laboratory work in hydrostatics is not very essential if the teacher is properly equipped for classroom demonstration. However, it would be interesting and profitable in communities where gas is sup- plied to the laboratory, to have the student measure the gas pressure by means of a water column.

Atmospheric Pressure, L. Begeman

Science Bulletin

Having learned the meaning of "pressure" from the study of hydrostatics, the pupil is easily led to understand the striking phenomena of atmospheric pressure. He should readily appreciate that the term refers to the gravity pressure of the atmosphere.

What Are We Teaching In Biology?, C. W. Lantz

Science Bulletin

This subject in order to be of real value must be an actual study of plants and animals. I have observed in my teaching that pupils, when given recognition characters of trees, may be able to pass a satisfactory examination on these characters, but fail to recognize the trees they describe when they see them in the field. They have simply memorized words that mean nothing to them.

Stress Pertinent Facts In Health Teaching, Belva W. Swalwell

Science Bulletin

In the past, much of the health information which high school pupils acquired was handed down to them traditionally. They listened to what their elders had to say and seldom questioned the validity of it. Assertions to the effect that a buckeye carried in one's pocket would prevent rheumatism; that a piece of salt fat pork bound about the neck would counteract diphtheria; or that some malodorous substances would, if breathed, ward off certain communicable diseases were considered as truths and were passed on to the next generation. Since health is now taught in our high schools by teachers adequately …

Highway Signs In Science Teaching, Winifred Gilbert

Science Bulletin

Let me assume that the General Science teachers of the state have been well prepared for their work and that at the present time they are more or less efficient teachers. Still there is the ever present task of keeping up with the curricular and learning studies that are going on in the field of General Science. New texts are appearing, yearly, new studies on content and methods seem to be on the increase and it takes rather nimble stepping on the part of the teacher to keep pace.

A correspondent reminds us that some teachers of science leave the impression in the class that our present knowledge of science was given to the world ready made or grew out of the presses that printed the text.

Laboratory Equipment And Experiments For Determinations Of Density, L. Begeman

Science Bulletin

Laboratory experiments in Density require the following apparatus: beam balances, meter sticks, graduates, calipers, tumblers, test tubes, and hydrometers. There should be as many of each as possible· in order to reduce the amount of group work. The objects for study should include pieces of lead, zinc, marble, paraffin, beeswax, glass stoppers, shot, gasoline and solutions of salts such as blue vitriol.

Hydrostatics, L. Begeman

Science Bulletin

The teacher may introduce this subject to the class by reference to the meaning of "pressure" as used in mechanics. Explain to them that the gauge pressure in a steam boiler or auto tire refers to the number of pounds pressure on each square inch of inner surface. Sometimes a problem will make it clear.

Something From Nothing, W. H. Kadesch

Science Bulletin

Matter made while you wait-hydrogen, helium, oxygen, iron or what will you have? No, it has not quite come to this! But the time-honored law of conservation which states that matter is neither destructible nor creatable is no longer accepted as unquestionably and universally true.

Laboratory Upkeep, R. W. Getchell

Science Bulletin

Proper care of the laboratory is the phase of the high' school chemistry teacher's task most apt to be neglected. This and later articles will point out some of the " little things that make perfection."

Fall And Winter Material In Animal Husbandry, H. Earl Rath

Science Bulletin

Swine are now going to market in large numbers. This offers an excellent opportunity to study market types as represented in the herd and compare them with the sows from which they were produced. If brood sows for spring litters have not all been selected, the teacher has some valuable work for pupils in selecting the better prospects from the available groups.
