Laboratory Equipment And Experiments For Determinations Of Density, L. Begeman
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.
Fall And Winter Material In Animal Husbandry, H. Earl Rath
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.
Hydrostatics, L. Begeman
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.
What Are We Teaching In Biology?, C. W. Lantz
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
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 …
Something From Nothing, W. H. Kadesch
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.
A Correspondent Reminds Us . . .
A Correspondent Reminds Us . . .
Science Bulletin
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.
Editorially Speaking
Science Bulletin
We greatly appreciate the friendly comments on the first issue of the SCIENCE BULLETIN from our readers; and we have tried to answer your questions. In these first issues we are of necessity "feeling our way in the dark". You only, friendly reader, can give us light.
Laboratory Upkeep, R. W. Getchell
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."
Highway Signs In Science Teaching, Winifred Gilbert
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.
Introducing Ourselves
Science Bulletin
With this issue of the Science Bulletin, the Iowa State Teachers College enters upon a definite program of class-room service to the teachers of high school sciences of the state. This big family of fifteen hundred science teachers arc handling a b ranch of instruction which is unsurpassed, not only in its fascination but in its rapid development and change in teaching methods and subject matter. You, fellow science teacher, as a member of our great state educational system, are entitled to all of the assistance which this state supported Teachers College can offer you.

Some Suggestions For Fall Laboratory Work In Animal Husbandry, H. Earl Rath
Some Suggestions For Fall Laboratory Work In Animal Husbandry, H. Earl Rath
Science Bulletin
Now that the seed corn is selected for next spring, and the frost has put an end to grasses and other outdoor crops, the agricultural instructor often feels that little outdoor material is available for further study. With this in mind I would like to present a laboratory exercise that will provide for some valuable outdoor work, and can be used as the basis for much classroom study as well.
Some Suggestions For Winter Study Of Biology In High Schools, Roy L. Abbott
Some Suggestions For Winter Study Of Biology In High Schools, Roy L. Abbott
Science Bulletin
Considerable criticism has recently been directed against the commonly accepted methods of teaching Biology in our secondary school and colleges. John Burroughs once re- marked that he had never dissected an animal and was glad of it, implying by this, I take it, that we do not learn Nature by dissecting her children. Recently Wheeler of Harvard, has voiced a similar criticism by saying that our teaching of Biology is suffering from academic dry rot; that laboratory dissection of a dead animal gives the student a knowledge of the details of structure of that animal without giving any knowledge of, …
Organize That Club!
Science Bulletin
Now is the time to organize your Science Club. The cold months are club months. With the closing of the out-door athletic sports the pupils naturally turn to inside activities as outlets for their energies.

What is a perfect recitation? In the fifteenth chapter, page 201 of Dewey's "How We Think" will be found a statement of Herbart's formal steps of instruction. They have been designated as the five perfect steps of a recitation. As Dewey says, "These five steps have had greater and better influence on the 'hearing of lessons' than all other methods put together." Dewey further states "that the underlying notion of these steps is that no matter h ow subjects vary in scope and detail there is one and only one 'best' way of mastering them since there is a 'single …

The Beginning Course In High School Physics, L. Begeman
The Beginning Course In High School Physics, L. Begeman
Science Bulletin
All authorities on the teaching of physics are agreed that the beginning work of a class in high school physics should be distinctly concrete in nature. It should consist of such subject matter as will readily connect up with the acquired concepts of the student. It is best not to begin with the unfamiliar, abstruse concepts of force, motion and acceleration usually placed first in the high school text.
