Presents an activity that is part of a unit on topography and land masses in the earth science curriculum. Involves students learning about scientific inquiry, comparing a model with what it represents, making and interpreting scale drawings, learning how to use new instruments, and learning about computation and estimation. (JRH)

Addresses the facilitative role of teachers in helping students develop the ability to evaluate ethical issues that arise from transplantation technology. Describes the implementation and evaluation of a bioethics unit. Findings indicate that student-centered strategies can provide opportunities for students to clarify, reflect critically on, and…

Describes an activity that engages students in the outdoors and provides them with the opportunity to stop and observe the world unedited for a few minutes. Involves students narrowing and then broadening the focus of their senses. (JRH)

Describes a method for using cardboard and paper to make a pump for blowing up balloons. Includes construction diagrams, suggestions for application, and comparison of this force pump with those made commercially. (DDR)

Outlines a workshop for teachers that illustrates a method of extracting DNA and provides instructions on how to do some simple work with DNA without sophisticated and expensive equipment. Provides details on viscosity studies and breaking DNA molecules. (DDR)

Presents experiments that introduce natural product chemistry into high school classrooms. In the laboratory activities, students isolate and analyze the oil in orange peels. Students also perform a steam distillation and learn about terpenes. (DDR)

Presents two activities, the "Super Bubble" that challenges students and parents to blow the biggest bubbles and "For Fingers Only" that asks them to duplicate a pattern of blocks using only the sense of touch. (JRH)
