General biology courses should be planned and taught in colleges according to widely accepted theories and laws of biology. A list of 24 such principles is provided around which general biology courses could be structured. (PS)

A field camp was arranged to provide positive experiences in learning about the history, geography and ecology of an area. (PS)

The First Law of Thermodynamics is discussed based on childhood experiences such as playing with seesaws, falling balls, thrown balls, bouncing balls, friction, combustion, and arithmetic. (DF)

If physicists don't break away from their presently self-imposed restraints, others will take over as scientific generalist. (Author/DF)

Can health education at the elementary level provide total involvement of the student? The Ethel K.

The author points out that two models of creation and evolution designed to explain life forms are equally competent and one is not less scientific than the other. Both of the models should be included in school curriculum. (PS)

International Center of Insect Physiology and Ecology (ICIPE) is an organized effort to study physiology, endocrinology, genetics, and related processes of five insects. Location of the center in Kenya encourages developing countries to conduct research for the control of harmful insects. (PS)

Research for insect control has been quite complex. However, recent knowledge of using insect hormones against them has opened new vistas for producing insecticides which may be harmless to human population. Current areas of insect research are outlined. (PS)

Discusses the charge independence, wavefunctions, magnetic moments, and high-energy scattering of hadrons on the basis of group theory and nonrelativistic quark model with mass spectrum calculated by first-order perturbation theory. The presentation is explainable to advanced undergraduate students. (CC)

Using syringes, a hydraulic press was constructed and mechanical advantage and efficiency were calculated. (CP)
