Enough Already? Linking Science, Geography, Mathematics, And Sociology Through Population Study, Roxanne Greitz Miller, Lilian M. Were
Enough Already? Linking Science, Geography, Mathematics, And Sociology Through Population Study, Roxanne Greitz Miller, Lilian M. Were
Education Faculty Articles and Research
In several previous Issues In-Depth columns, science topics deeply affected by population size--such as climate change, fuel and agricultural resources, and ecology--have been discussed. In this column, we will discuss the issue of population growth in developed and developing countries, why this is an important topic to discuss with young adolescents, and how interdisciplinary connections can be made between science and several other subject areas through an examination of populations across the globe.
How Do We Know There Is A Population-Environment Problem?, Peter J. Taylor
How Do We Know There Is A Population-Environment Problem?, Peter J. Taylor
Working Papers on Science in a Changing World
Five fictional friends of the author have agreed to meet and talk, hoping that he was right when he claimed that discussion crossing the usual boundaries of their fields would enrich their different inquiries and concerns. Ecolo, a natural and human ecologist, breaks the ice. He wants to marshall scientific knowledge to persuade others of the seriousness of the population problem. He is questioned by Philoso, whose philosophical bent leads her to observe the models that people use and to ask how they support the claims they make. In turn, the other three join in: Activo, an activist who is …
Higher Population And Twin Row Configuration Does Not Benefit Strip Intercropped Corn, M. M. Harbur, R. M. Cruse
Higher Population And Twin Row Configuration Does Not Benefit Strip Intercropped Corn, M. M. Harbur, R. M. Cruse
Journal of the Iowa Academy of Science: JIAS
Increased corn (Zea mays L.) grain yield with strip intercropping, made possible because of increased edge effects, makes this soil-conserving crop production system appealing to farmers. The objective of this study was to determine the population and row configuration needed to optimize the additional yield potential in each outside corn row. Treatments 'included: 74, 99, and 124 thousand plants ha-1 were grown in twin rows and 74 thousand plants ha-1 grown in single rows. Single rows or twin row centers were spaced 0.76 m. The experiment was conducted at four central Iowa sites during 1996 and 1997. Grain …
Secondary And Elementary School Use Of Live And Preserved Animals, Marvin B. Emmons
Secondary And Elementary School Use Of Live And Preserved Animals, Marvin B. Emmons
Education Collection
The broad use of living animals in elementary and junior school programs that are currently in vogue will be discussed as well as their use in biology classrooms at the senior high level. A comparison will be made of the present use of animals in the biology curriculum at the high school level, both living and preserved, with the use levels some ten and fifteen years ago. The implications of wildlife habitat encroachment and subsequent depletion of native species of classic animal models as well as some alternatives will be reviewed.
