A Not-So-Obvious Solution To The Black Beetle Puzzle Jan 1972

A Not-So-Obvious Solution To The Black Beetle Puzzle

Iowa Science Teachers Journal

True or false: Most desert animals whose life styles keep them out and around during the day are light in color because, as scientists know, light coloration reflects heat and desert animals would naturally evolve in that direction?


A Comparison Of Girls' Achievement In Unisexual And Bisexual Physics Classes, Robert L. Hare Jan 1972

A Comparison Of Girls' Achievement In Unisexual And Bisexual Physics Classes, Robert L. Hare

Iowa Science Teachers Journal

A battle cry heard for the past few years is, "Why have physics enrollments not increased?" There have been many possible solutions to the problem, and many of them have had some success. For example, the Physical Science Study Committee and Harvard Project Physics have done much in creating interest in physics and thus have helped to increase physics enrollment. Also, the emphasis on laboratory experiences and the increase in audiovisual aids have contributed in making the physics classroom more enticing. It is the writer's opinion that a possible source of physics students might come from those of the female …

Lightning Jan 1972

Lightning

Iowa Science Teachers Journal

Lightning supposedly does not strike twice, but once is too much for the more than 100 humans and thousands of animals that die each year from lightning bolts. University of Wisconsin-Madison electrical engineer Theodore Bernstein told scientists gathered at the American Association for the Advancement of Science conference recently how electricity affects living things.


Group Independent Study: A Unique Approach To Undergraduate Research, James E. Privett Jan 1972

Group Independent Study: A Unique Approach To Undergraduate Research, James E. Privett

Iowa Science Teachers Journal

Briar Cliff College has a program of independent study in the student's major field during the junior and senior years. In the past the program was used for library research projects and independent laboratory projects. In all cases the projects were truly independent, that is, separate projects for different students with no interconnections between projects. The investigator felt that it would be advantageous if all of the senior chemistry majors and some of the junior chemistry majors who felt ready for the experience would work on the same general research project but with each student studying just one aspect of …


Do Birds Have A Built-In Magnetic Direction Finder? Jan 1972

Do Birds Have A Built-In Magnetic Direction Finder?

Iowa Science Teachers Journal

How do birds find their way south in the fall? Some may have a built-in magnetic compass to help them find the way. At least there is an upsurge of scientific interest lately in the possibility that birds can orient themselves for their seasonal migrations by using the earth's magnetic field as a navigation aid.

Seeking The Meaning Of The Missing Bones Jan 1972

Seeking The Meaning Of The Missing Bones

Iowa Science Teachers Journal

What a scientist doesn't find at an archeological dig can be just as important as what he does find, if he can figure out what is missing and why. The search for just such missing evidence and its meaning has set University of New Mexico archeologist Lewis R. Binford roaming Alaska's Brooks Range, interviewing Nunamiut Eskimos and exploring ancient Eskimo dwelling sites there.


Hunting Ddt In Small Birds: Migratory Fowl Could Be A Link Between Pesticides And Hawks, Falcons Jan 1972

Hunting Ddt In Small Birds: Migratory Fowl Could Be A Link Between Pesticides And Hawks, Falcons

In the past two years at The University of Iowa, we have developed an offering in science education for in-service elementary teachers which provides the elementary school teacher with both an empathy for science and some security with the process-oriented technique.


Science For The Educationally Uninvolved Student, Joe R. Moore Jan 1972

Science For The Educationally Uninvolved Student, Joe R. Moore

Iowa Science Teachers Journal

In looking at science in today's high schools, one can come up with the following statistics. There are approximately four million students at each grade level between grades nine to 12. In biology classes we find 1.85 million students, in chemistry about 1.25 million and in physics only .25 million students. Over half of these students are enrolled in terminal or "slow-track" science courses, where they are neglected or forgotten, taught by the beginning teacher in a non-lab-oriented classroom. Almost every high school has a science course where the so-called "slow-learners" have been placed. These courses may come under a …

A Comparison Of The Effects Of A Team Approach And A Conventional Approach On Achievement In High School Biology, Paul Joslin, John Montean, John Schmitt Jan 1972

A Comparison Of The Effects Of A Team Approach And A Conventional Approach On Achievement In High School Biology, Paul Joslin, John Montean, John Schmitt

Iowa Science Teachers Journal

It is very easy to come by reports in support of almost any new practice in education. Teachers would rather report favorable results and journals would rather print them. It was the many published reports enumerating the advantages of team teaching that first interested us in a team teaching experiment. At the time we started in 1964, we summarized 141 publications with team teaching in their titles. There are only a limited number of advantages and disadvantages that can be hypothesized for any particular practice. It was not surprising, therefore, to find that recent reports tend to merely reassemble what …


What Is A.T.T.V. Biology?, Charles Frederick Jan 1972

What Is A.T.T.V. Biology?, Charles Frederick

Iowa Science Teachers Journal

A.T.T.V. Biology (Audio-tutorial Television Biology) is an approach to teaching a subject which is paced by closed circuit educational television. The curriculum material of the course is divided into units of work (modules). Each module consists of one week's classroom activities. For each module there are objectives and learning experiences to be completed within that week. The module suggests the minimal work expected of the student, and the student works directly from the module guide. When the student has completed the minimal learning experiences, he is free to pursue additional activities that are listed in the module. This is where …


Rebuilding A Tornado To See What Makes It Tick Jan 1972

Rebuilding A Tornado To See What Makes It Tick

Iowa Science Teachers Journal

Hurricanes can be studied from airplanes flown through them and from instruments located in their paths. But even if a meteorologist or engineer could predict the narrow path of a tornado, any instruments he might place in its path would be swept away by the force of the storm.


A Simple Machines Lab For Seventh Grade Students, Peter H. Sweedy Jan 1972

A Simple Machines Lab For Seventh Grade Students, Peter H. Sweedy

Iowa Science Teachers Journal

Having taught physical science for two years at the high school level, my new assignment to teach seventh grade science was met with mixed emotions. I had heard that junior high students were very energetic (mostly for mischief) and were very limited in learning ability, due to a low reading level and a lack of mathematical skills. I know I had also wondered, like many of you in high school and college teaching, just why did high school age students have such poor concepts of motion, energy, light, sound and graph interpretation and use.

A Learning Activity Package Approach To Junior High School Science, Jerry Cunningham, Ross Iverson Jan 1972

A Learning Activity Package Approach To Junior High School Science, Jerry Cunningham, Ross Iverson

Iowa Science Teachers Journal

Our goals were to have a low-structured student centered program that made the best use of our physical facility, equipment, and teacher power. As a result, we formulated a design which included a format, procedures, and a set of materials. We feel that our design is adaptable to many situations and may provide some ideas for you. The courses we teach are exploratory. We hope to offer the student a wide variety of new experiences while developing a continuing interest in the study of science and a systematic approach to solving problems.

So You Want To Be An Outstanding Teacher!, Barton Philipps Jan 1972

So You Want To Be An Outstanding Teacher!, Barton Philipps

Iowa Science Teachers Journal

Great teachers are great because of the long vacations, short working day, easy work (if you call it work), and good pay. WHAT? Who said that? Truly GREAT teachers rarely take a vacation and work overtime without pay, to guide the students in learning situations. And as for the pay, the garbage collectors in many areas make more than the teachers.
