We describe a polymerase chain reaction (PCR) protocol suitable for use in secondary schools and colleges. This PCR protocol can be used to investigate genetic variation between plants. The protocol makes use of primers which are complementary to sequences of nucleotides that are highly conserved across different plant genera. The regions of…

The two general concepts of how living organisms originated are defined: namely, common ancestry evolution and the abrupt appearance of completed organisms on earth. The fossil record is examined from the deepest first fossil-bearing rocks to the top of the geologic column. Evidence obtained from fossil museums is presented so students can…

Suggests instructional strategies for biology teachers confronted with creationism in the classroom and ways of dealing with the literal view of the public regarding the Bible. Supporting documentation (such as Christian ideas supporting scientific spirit and inquiry and definitions of the earth) is included in appendices. (JN)

To test the literal biblical account of Noah's flood, four sources of possible flood waters were evaluated to determine if a natural (as opposed to supernatural) explanation is possible. Sources include rain, hydrothermal springs, and two types of cometary impact. Thermodynamic constraints preclude a natural means of accounting for the flood.…

Discusses an Arkansas State law that required balanced treatment of creationism and evolution in the study of human origins. Describes arguments for and against the law as presented at a courtroom trial in which it was decided that the law was unconstitutional, and that creationism had no legitimate educational purpose. (Author/MJL)

The 1981 court trial concerning a challenge to the constitutionality of Arkansas' Act 590, the Balanced Treatment for Creation-Science and Evolution-Science Act, is described in detail. Arguments, courtroom strategies, and personalities are discussed, and the ruling of unconstitutionality is outlined. (MSE)

Reviews results of a California trial concerning the teaching of evolution in public school classrooms. Also lists recent legislation in the states of Florida, California, Minnesota, South Dakota, Kansas, Illinois, Iowa, Texas, and Arkansas. (CS)

Describes an exercise whereby a biology class used a stairway to illustrate how fossiliferous rock strata were deposited, the oldest on the bottom and most recent at the top. Each step represents a dated boundary between adjacent geological ages, and each riser is labeled as a geological unit. Geological time is compressed to 365 days. Offers…

Examines three anecdotal cases of the teaching of evolution theory in an exploration of the best approaches for teaching about evolution. Three instructional options are presented: (1) readings in natural history, (2) commercially prepared activities, and (3) the use of small-group (peer) discussions. (LZ)

Urges an approach to the teaching of history that takes the largest possible perspective, crossing time as well as space. Discusses the problems and advantages of such an approach. Describes a course on "big" history that begins with time, creation myths, and astronomy, and moves on to paleontology and evolution. (DK)

Relates the experience of students and a teacher in an alternative high school in designing a biology curriculum based on Foxfire practices. Describes student efforts to gain approval from school officials to study evolution and creationism and the conflicts in values and belief systems among the students. (LP)

In this article, the author presents a two-week evolution unit for his biology class. He uses Maria Sybilla Merian (1647-1717) as an example of an Enlightenment mind at work--in this case a woman recognized as one of the great artists and natural scientists of her time. Her representations of butterflies, caterpillars and their pupae, and the…

In this article, the author points out the decision of U.S. District Judge John E. Jones III, issued Dec. 20, regarding the constitutionality of Dover, Pa., district's policy that promotes "intelligent design" in public school sciences. In the ruling, Judge Jones not only found the district's policy promoting intelligent design…

This laboratory exercise introduces students to a fundamental tool in evolutionary biology--phylogenetic inference. Students are required to create a data set via observation and through mining preexisting data sets. These student data sets are then used to develop and compare competing hypotheses of vertebrate phylogeny. The exercise uses readily…

The presidency of George W. Bush has polarized the church-state debate as never before. The Far Right has been emboldened to use religion to govern, while the Far Left has redoubled its efforts to evict religion from public life entirely. Fewer people on the Right seem to respect the church-state separation, and fewer people on the Left seem to…
