Presents an exercise to be used after students have been introduced to Mendelian genetics and the Punnett square. Allows students to grasp the mechanics of Mendelian genetics. (DDR)

Presents a creative, hands-on activity for teaching measurement skills inspired by Antoine Laurent Lavosier and a product called polyacrylamide spikes for students to develop their metric measurement skills and boost their math proficiency as they interpret data and results from their investigations. (ASK)

Presents an activity in which students construct a roller coaster to illustrate the concept of physics as part of a forces, motion, and energy unit for their physics course. (ASK)

Describes an activity that reduces the biosphere to a water-filled jar to simulate the relationship between cellular respiration, photosynthesis, and energy. Allows students in high school biology and related courses to explore quantitatively cellular respiration and photosynthesis in almost any laboratory setting. (ASK)

Establishes whether the use of the newly developed audiopilot facilitates both hands-on exploration and the understanding of scientific principles in a science center. Suggests that auditory commentaries are a good way of communicating difficult scientific concepts, especially to girls. (Author/SAH)

Describes a directed research project that examines the territorial and aggressive behavior of crickets. Presents behavioral ecology laboratory experiments in which students test the hypothesis that crickets with established territories are more likely to win confrontations that intruding crickets. (Contains 11 references.) (ASK)

Describes an activity-based science program. Provides information on background thinking, selecting an activity, planning for instruction, and following up. Discusses choosing activities that meet the needs of students while still fulfilling curriculum requirements and reaching personal academic goals. (SAH)

Describes how to effectively get students who have difficulty listening, reading, and following directions to pay attention. Presents activities on making iced tea and covering a book. Activities include a materials list and a list of procedures with extension activities and conclusions. (SAH)

Reports the effects of Bacillus thuringiensis var. Kurstaki (BT), which is highly toxic, to a non-target lepidopteran, the Painted Lady butterfly. Indicates that BT kills some Painted Lady butterfly larvae at the lowest dilution tested after 48 hours. (ASK)

Describes a science experiment involving plant seeds where students observe the germination and plant growth. (YDS)

Describes the three stages of a field trip and reviews stage 1, weekend field trips, which focuses on an organism's morphology, behavior, and ecology. Presents activities on salamanders, small mammals, fish, birds, and bats. Explains the difficulties of weekend trips. (YDS)

Presents three quote box puzzles in which given letters are dropped vertically in each column (given order does not necessarily represent the appearance) and form a quotation when read from left to right, line by line. (YDS)

Explains the advantages and disadvantages of verification experiments in classrooms from the secondary school science teacher's point of view and discusses the reasons for difficulties and resistance in replacing verification experiments with inquiry experiments. (Contains 19 references.) (YDS)

Explains the benefits of using plastinated specimens on students' conceptual understanding. Argues for dropping the dissection component from introductory biology courses due to threatened animal populations and the high cost of providing some of the specimens. Describes how to use plastinated specimens in an investigative laboratory approach.…

Presents three biology activities involving insects that demonstrate basic ecological principles related to the forensic sciences. (Contains 15 references.) (YDS)
