The Migration Of Birds: Part I, O. R. Clark
The Migration Of Birds: Part I, O. R. Clark
Science Bulletin
Among the most characteristic and familiar activities of our birds are their regular seasonal movements between their winter homes and their summer nesting sites.
The Nature Of Adaptations, O. R. Clark
The Nature Of Adaptations, O. R. Clark
Science Bulletin
In the October number of this bulletin, in a discussion of the influence of environment upon the growth and development of plants, the statement was made that, on the whole, plants are quite well adapted to the conditions under which they grow. As to the manner by which this ''fitness” has arisen there are some differences of opinion and, in the opinion of the writer, a great many misunderstandings. This is a question to which no ''cut-and-dried'' answer can be given but to which a fundamental principle of biology may be applied.
Environment As A Factor In The Growth And Distribution Of Plants, O. R. Clark
Environment As A Factor In The Growth And Distribution Of Plants, O. R. Clark
Science Bulletin
The form and appearance of plants and the activities which they carry on are due in large part to the inherited characteristics of their ancestors. The influence which heredity exerts should be clearly and forcefully presented to students. At the same time the expression of the hereditary traits may be greatly modified by the conditions under which! the plants grow.
Insects And Man, Roy L. Abbott
Insects And Man, Roy L. Abbott
Science Bulletin
Because of their relationship to dangerous human parasites, insects have been responsible for the death of more people than all other animals put together. Confirmation of this astounding statement can be seen in the close relationship between houseflies and typhoid fever, between rat fleas and plague, tsetse flies and sleeping sickness, and that between mosquitoes and yellow fever and malaria.
Winter Birds Of Iowa, O. R. Clark
Winter Birds Of Iowa, O. R. Clark
Science Bulletin
The study of birds should certainly form an important unit of every course in high school biology. Furthermore, this study should be continued through the entire school year in order to secure the most desirable results. The fall is an excellent time to begin the study because the number of birds to be found is not so great as to ca use confusion and the students will be able to become familiar with the means of identification and the common recognition marks of many of our common birds.
Household Insects, Roy L. Abbott
Household Insects, Roy L. Abbott
Science Bulletin
It was said above (see November Bulletin) that practically every animal is attacked by one or more kinds of insects. Man constitutes no exception to this statement, and it is my purpose in this article to deal with a few of the insects commonly found in or around our homes. Perhaps the most familiar of all household insects is the housefly.
Living Material In The Laboratory, O. R. Clark
Living Material In The Laboratory, O. R. Clark
Science Bulletin
Living plants and animals serve as valuable aids in stimulating interest in the biology course and, during that part of the year when field trips are impossible, provide material for the study of habits and the relation of organisms to their environment. Laboratory conditions are of course artificial but they should be made as nearly natural as it is possible to make them.
Insects And Man, Roy L. Abbott
Insects And Man, Roy L. Abbott
Science Bulletin
Biologically speaking, insects may be called a highly successful group, and much of this success is due to their adaptability to the conditions of their environment. They are found everywhere, and eat almost everything. All of the large groups of insects are world-wide in their distribution, though the most widely distributed are the beetles.
Insects And Man, Roy L. Abbott
Insects And Man, Roy L. Abbott
Science Bulletin
Mrs. Jiggs, in the cartoon, "Bringing up Father," frequently calls her husband an insect. This is a flagrant misuse of the term as an insect never has fewer nor more than six legs. It may be wingless as are the bedbugs, two winged as are all flies, or four winged as the grasshoppers, but no normal insect ever has more or less than six legs and by this one positive character you may know them.
Collecting Specimens At Night, Roy L. Abbott
Collecting Specimens At Night, Roy L. Abbott
Science Bulletin
Many teachers of biology don’t realize how much valuable biological material may be collected after dark. In fact, certain specimens, as grasshoppers, earthworms, and various species of amphibia, are most easily captured then.
Introducing The Biology Course In The Classroom, Roy L. Abbott
Introducing The Biology Course In The Classroom, Roy L. Abbott
Science Bulletin
The success of any course in high school science often depends upon the interest aroused in it during the first days of its presentation. This interest is particularly easy to arouse in biology, chiefly, l suppose, because people are always interested in living things, or things that have been alive. Moreover, though he does not recognize it as such, nearly every pupil has considerable biological knowledge when he first comes to class, and it is this preliminary knowledge which can be made a strong entering wedge into his interest in the subject.
Cockroaches For Laboratory Study, Roy L. Abbott
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.
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.
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, …
