Simple Radiation Studies In Biology, C. L. Christensen, D. J. Schmidt

Iowa Science Teachers Journal

Radioisotopes are a part of modern biological science. Radiation studies can be carried out without great expense. Thus they are available for the secondary level. Projects are easy to develop and can be adapted to any area of biological science. We would like to encourage all biology teachers to incorporate the use of radioisotopes into their programs.

Junior High Science As A Foundation, Leona K. Adler

Iowa Science Teachers Journal

Science programs designed for junior high school are usually based upon the assumption that this level includes grades 7, 8 and 9 - although, of course other types of groupings have been explored. We must also recognize the assumption that junior high school science is neither the first nor the last exposure of students to science.

Resource Heritage And Conservation Education, Arnold O. Haugen

Iowa Science Teachers Journal

Good conservation involves wise use of resources. Consideration must be given to long-time use by people of both this and future generations. In some cases good conservation dictates that we make only limited or no use of a particular resource. Examples of the latter are Iowa's few remnant native prairie areas and relatively undisturbed forest areas. Iowa's resources also include its soils, water, woodlots, wildlife, fishes, and geological, paleontological and historical sites. Availability of Iowa resources for future use will depend on how we manage to use or abuse them today.
