The Inert Gases, R. W. Getchell
The Inert Gases, R. W. Getchell
Science Bulletin
Nitrogen gas is lazy. A chemical revolution may enlist and lead away nearly every other element and compound in the air, but nitrogen will stay at home and refuse to become excited. Less than forty years ago, Lord Rayleigh in England made use of this characteristic by removing the other components of the air and collecting the remaining supposedly pure nitrogen in order to study it.
We, The Jury, R. W. Getchell
We, The Jury, R. W. Getchell
Science Bulletin
Iowa high schools may justly be proud of their chemistry courses and of their chemistry teachers. The state ranks low in the number of schools offering this science but high in the quality of its teaching staff. One sure criterion of instructional efficiency is growth - a growth based upon the frank recognition of mistakes and intelligent effort to correct them.
Chemical Lecture Experiments, R. W. Getchell
Chemical Lecture Experiments, R. W. Getchell
Science Bulletin
Lecture experiments demand more time, require higher technical skill, and afford greater pupil interest than any other phase of chemistry teaching. As a corollary, we may add that they are most neglected, but if you name the teachers who are noted for their interesting, instructive, and skillful classroom demonstrations, you are calling the roll of chemistry teachers of the first rank.
Science Minded, Harold E. Murphy
Science Minded, Harold E. Murphy
Science Bulletin
When we are trying to be "air minded " and "peace minded" why not go a little further and be 'science minded"? The aeronautic field has as its champion, Colonel Lindberg; the Peace Federation has as its champion, Ishbell McDonald; but where is the youthful champion of the field of chemical science? In this day of scientific advancement, a champion is surely needed to bring t h e achievement of chemical science to the people. Someone has said, "Science is the Creator's chest of tools. Human progress is man's learning to use these tools."
Professional Growth, R. W. Getchell
Professional Growth, R. W. Getchell
Science Bulletin
The first class provides bits of scientific information which can be interspersed in class discussions. Such items will add interest to the class work and may indicate new and modern uses for chemical substances and appliances. They are found in such publications as Popular Science Monthly. The second class of articles are indispensable to good teaching.
Professional Growth, R. W. Getchell
Professional Growth, R. W. Getchell
Science Bulletin
An official in a small school system was discussing the requirements for a good teacher. "We prefer teachers," he said, "who will outgrow their position in our school." What greater challenge to professional growth could be offered to a teacher in service?
Laboratory Upkeep, R. W. Getchell
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.

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."
