Biology Or Chemistry? Which Should Come First?, Gerald H. Krockover

Iowa Science Teachers Journal

With the many changes that are takin g place in our science curriculum, many of us tend to forget the necessity of analyzing the sequence in which these science courses are offered. Of particular importance is the sequence of chemistry and biology offerings to the student and our reasons behind one sequence over another.

Optic Nerve Size In Blind And Normal Mice, Margaret L. Watson, Jean E. Mckinnie, Donald M. Evans Jan 1965

Optic Nerve Size In Blind And Normal Mice, Margaret L. Watson, Jean E. Mckinnie, Donald M. Evans

Proceedings of the Iowa Academy of Science

Measurements of eyes and optic nerves of blind and normal mice were taken at ages ranging from 1-60 days. The mice used were from a Bagg albino strain in which a dominant mutation for blindness had occurred. The size of the optic nerve appears to be dependent upon the development of the eye. Optic nerves from blind eyes are smaller than those from normal eyes, and optic nerves from blind eyes without a lens and with a folded retina are smaller than those from eyes with a lens, even though the lens is vacuolated and the cornea is thickened.

Labless Laboratory In High School, Mary Nicholas Jan 1965

Labless Laboratory In High School, Mary Nicholas

Iowa Science Teachers Journal

The modern innovations in the science curriculum - Chem-Study, BSCS, and PSSC - are all seemingly orientated to the larger high schools with large enrollment and well-developed laboratories and equipment. Are the small, underdeveloped schools being bypassed in the necessary imparting of scientific knowledge?

The Histological Effects Of Tapazole On Rat Thyroids, Hearts, And Adrenals, Wade L. Collier Jan 1965

The Histological Effects Of Tapazole On Rat Thyroids, Hearts, And Adrenals, Wade L. Collier

Proceedings of the Iowa Academy of Science

The anti-thyroid drug Tapazole, when fed to white rats at the dietary level of 0.1% Tapazole in finely ground laboratory meal, produces changes in body weight, thyroid weight and in the histological composition of the thyroid. Histological examination shows that the affected thyroids have undergone hypertrophy and hyperplasia. Tapazole does not seem to affect rat hearts or adrenals.


Sexual Dimorphism In The Dorsal Fins Of Ollentodon And Skiffia, Mexican Goodeid Teleosts, Guillermo Mendoza Jan 1965

Sexual Dimorphism In The Dorsal Fins Of Ollentodon And Skiffia, Mexican Goodeid Teleosts, Guillermo Mendoza

Proceedings of the Iowa Academy of Science

The dorsal fins of males of Ollentodon multipunctatus, Skifiia lemae and Skifiia variegata differ from the dorsal fins of the females. The first 4-5 rays of the male dorsal fins have a spine-like appearance and are separated from each other by a deep notching at the periphery of the fin membrane. The female fin is undifferentiated. The male dorsal is generally higher and longer at the base than the female fin. Similarly, the rays in the male fin are thicker than those in the female. Whereas most rays in the fin are bifurcated twice to form three or four terminal …


The Development Of Critical Thinking Through Science Instruction, Gerald H. Krockover Jan 1965

The Development Of Critical Thinking Through Science Instruction, Gerald H. Krockover

Proceedings of the Iowa Academy of Science

One of the major goals in science teaching is to develop critical thinking in each student. After instruction in science, we as science teachers, hope that students have learned to analyze scientific data, to interpret data which will allow them to arrive at reasonable conclusions, and to evaluate approaches to problem solving in science. At Middle School, Bettendorf, Iowa, one of our major goals is to develop the ability of each student to think and analyze problems in relation to his or her ability. To go along with this, each course in science is designed with an attempt to continually …
