Describes a process known as parthenogenesis which produces cloned, early-stage embryos and human embryos generated only from eggs. Speculates that this technology puts therapeutic cloning within reach. (DDR)

Presents techniques used for disinfestation of plant material, preparation of equipment and media, and laboratory procedures for tissue culture using cauliflower. Details methods for preparing solutions and plant propagation by cloning. (CW)

Describes a basic biotechnology investigation that includes restriction and ligation of plasmid DNA, transformation of bacteria and cloning of these bacterial cells. Discusses laboratory procedures and another activity in the identification of unknown plasmids by studying agarose gel electrophoresis photographs. (CW)

Describes an activity used at the Washington Park Arboretum that helps students understand cloning through plant propagation. Students also learn how to make a pot from recycled newspapers and how to make soil that is appropriate for the plants. (DDR)

Describes the use of an oven bag as a sterile chamber for culture initiation and tissue transfer. Plant tissue culture is an ideal tool for introducing students to plants, cloning, and experimental design. Includes materials, methods, discussion, and conclusion sections. (SAH)

Discusses the legitimacy of teaching about astrology, extrasensory perception, UFOs, touch therapy, cloning dinosaurs, or any other unusual claims in the classroom. Suggests that bringing unusual claims to the science classroom is an opportunity to motivate students in the principles of scientific thought. (SAH)
