Examines the content knowledge of genetics as it is organized for solving effect-to-cause problems. Reviews proposed reasons explaining why students find genetics difficult to learn. Explains dominant and codominant inheritance patterns, multiple alleles, and X-linkage. (RT)

Described is an activity used to introduce the anatomy of the skeletal and muscular systems. A teacher conducted, video enhanced demonstration and a student activity are discussed. Included is a sample student laboratory paper. (CW)

Examines the procedural and philosophical perspectives taken by science in examining human characteristics. Discusses the different levels of accuracy of various scientific fields. Encourages discussion of what biological and behavioral sciences can and cannot reveal about complex human nature. Considers some characteristics of quality science…

Presents information on owl's taxonomy, characteristics, and influences on man. Describes owl pellets, which are digestive discards, and explains how they can be used to determine the owl's diet as a science activity. (PR)

The carpel is a highly modified leaf enclosing the ovules. This article describes methods for teaching about the evolution of the carpel and the nature of carpel fusion. Presents an illustration of the evolution of the most common types of compound pistil arrangement from the ancestral single-carpel marginal type of placentation. (PR)

Presents a directed-inquiry activity to take students one step beyond observation of how living organisms capture prey. Uses a field lab based upon predator-prey relationships to enliven the teaching of food web concepts to non-science-major freshman undergraduates. Can also be used in teaching high school biology students through college science…

Two statistical tools, the Chi-square and standard error approaches, are compared for use in Mendelian genetics experiments. Although the Chi-square technique is more often used, the standard error approach is to be preferred for both research investigations and student experiments. (BB)

Using aerial photographs to study shrubs biomass allows students to avoid unpleasant working conditions and to study communities that are inaccessible or distant. (BB)

A broad range of present microbiological work is discussed in order to indicate the many possible careers now open in microbiology. Some areas are immunology, environmental microbiology, agricultural, industrial, and food microbiology, and space microbiology. An employment outlook is also given. (MDR)

Some of the work of a modern medical geneticist is described. Also included is an employment outlook summary in medical genetics. (MDR)
