Describes an activity in which students receive individual questions (i.e., What is a sparkler made of and what makes it sparkle?) to answers from their "Aunt Gladys." Students must research the everyday question, discover the answer, and then translate the answer into the common language of the masses. (PR)

Discussed are the results of a test administered to nonmajor biology students on the topic of natural selection. The description of student conceptions, effects of instruction, and the effects of a belief in evolution are included. (KR)

A phenomenological explanation of this effect is provided. Suggestions for the inclusion of pyroelectric effects into a unit on electrostatics are given. (CW)

Explains how radiographs (from X-rays) can be used in elementary and middle-school curricula. (PR)

Reviews international studies that show that girls have a poorer command of physical concepts than boys. Examines factors that might explain this phenomenon and discusses whether or not boys have different learning styles than girls. Recommends that science course content must be structured to fit girls' skills and interests. (CFR)

Surveyed 232 college students in an introductory biology course on their attitudes and perceptions on aspects of biology that they should have covered in high school science. Results indicated majority of students felt very or somewhat familiar with the topics covered in the survey. A sizable majority of students were only somewhat familiar with…

Garlic is an ideal plant for the elementary classroom. It grows rapidly in water without aeration for several weeks and remains relatively free of microbial contamination. Simple experiments with garlic purchased at grocery stores can illustrate various aspects of plant growth. (PR)

Describes the construction of a variety of inexpensive, escape-proof, and safe insect homes--each complete with window, ventilation screen, and cover--so students can observe firsthand the intriguing world of insects. (PR)

Describes hands-on physical anthropology activities for teaching students about evolution. Using evidence found in hominid skulls, students conduct investigations that involve calculating ratios. Eight full-page photographs of skulls from the program Stones and Bones are included. (PR)

Describes children's books, songs, and innovative activities for introducing students to paleontology and skeletal structures. (PR)

Presents a series of exercises to help students understand the importance of the limits of taxonomic keys and to identify the appropriate levels. Introductory activities include having students classify screws, "gummy bears," and beans. (PR)

Considers topics about cell function often misunderstood, misrepresented, or omitted from biology textbooks: enzyme catalyzed reactions; RNA as a catalyst; protein levels in cells; amino acids; organic acids; glucose and fructose; gluconeogenesis; fatty acids and ketone bodies; diffusion; and transport across membranes. (Contains 25 references.)…

Describes an approach to teaching the scientific method where an outbreak of cholera within the school is simulated. Students act like epidemiologists in an attempt to track down the source of the contamination. (PR)

Describes a unit of hands-on activities on the corrosion of iron and steel. The unit uses the learning cycle and the science/technology/society approach. Three activities are presented. (PR)

Students discover science resources in their neighborhood that help them see the relevance and long-term applications of concepts learned in the classroom. Students explore people, objects, and geographic resources beginning in the school and extending out into the community. (MDH)
