Suggestions are presented for planning activities around the concept of endangered species. A sample of the classification system and a matching game are described. (SA)

An audio-autotutorial program for high school students is described which utilizes many appropriate audiovisual materials and serves as an alternative to the traditional lecture-discussion approach. (SA)

Describes an easy-to-use, inexpensive field trip/laboratory exercise designed to delineate the home ranges of small animals. Students participate in the design of the exercise; collection, analysis, and interpretation of data; and the presentation of results. Contains 19 references. (DDR)

Provides background information and detailed procedures for a lab involving pennies that enables students to discover information on scientific methodology, experimental design, and the determination of density. Contains 26 references. (DDR)

Presents the topic of linking the presence of life on Earth with the chemical evolution of the universe as a whole. The approach involves examining issues related to the biochemical unity of living matter and the chemical evolution of the galaxy. (DDR)

Describes a partnership between a teacher and a bus design engineer for the Flexible Corporation and the innovative, multidisciplinary unit on changes in invention and transportation that grew out of it. (JRH)

Recommends that teachers use real life opportunities and experiences to design experiments to motivate middle school science students. Focuses on the use of consumer testing to engage students in using the scientific method. (DDR)

Describes a simple computer-interface experiment for recording the response of an RC network to an arbitrary input excitation. The setup is used to pose a variety of open-ended investigations in network modeling by varying the initial conditions, input signal waveform, and the circuit topology. (DDR)

Argues that empowering parents is the first step toward improving females' achievement in science. Describes the Sisters in Science (SIS) program that aims to unite the role of parents with the other factors that promote female success in science. Discusses policy and practical implications that can be drawn from the work of the SIS program.…

Engages middle school students and preservice teachers in a long-term (16 weeks) investigation of the moon and provides an opportunity to share, via the internet, their observations with other students around the world. Explains the design of the study including multicultural connections, student observations, internet discussions, and…

Early and ongoing exposure to entomology promotes interest in insects, minimizes fear of nature, and instills appreciation for biodiversity. Three effective ways to introduce young children to the study of insects are: live collections for observation and investigation, re-creation of insects through artistic constructions to learn structure and…

Describes research that documents the falsification of laboratory results by chemistry and physics students. Discusses some factors that encourage students to fabricate results and why some students do not feel the need to falsify data. Contains 16 references. (DDR)

Describes an activity in which students reverse-translate proteins from their amino acid sequences back to their DNA sequences then assign musical notes to represent the adenine, guanine, cytosine, and thymine bases. Data is obtained from the National Institutes of Health (NIH) on the Internet. (DDR)

Describes an activity that teaches a number of scientific concepts including indirect measurement, Newton's third law of motion, manipulating and controlling variables, and the scientific method of inquiry. Uses process skills such as observation, inference, prediction, mensuration, and communication as well as problem solving and higher-order…

Discusses strategies to make life science classes more fun by planning activities that include preserved and live specimens. Discusses field trips and collections. (JRH)
