Describes a strategy to help students learn how to make detailed observations. Emphasizes making productive observations using complete, detailed, accurate statements or pictures. (SAH)

Describes a Standards-based activity entitled "The Limits of Learning" that is inquiry-based and designed for high school biology classes. The activity concerns how well repetitious material can be learned and improved upon. (YDS)

Introduces a bubble activity to teach about the nature of molecules, surface tension, light waves, and color. Explains how to make the bubble solution and includes a lab worksheet with answers to the questions. (YDS)

Presents science activities using material available in cafeterias. The quick activities entice students to investigate further the concepts introduced and also illustrate that common materials can behave in surprising ways. In addition, they make excellent at-home science experiments. (PR)

Describes an experiment that uses the cobra lily (Darlingtonia californica) and fruit flies (Drosophila virilis) to investigate predator-prey relationships in a classroom laboratory. Suggestions for classroom extension of this experimental system are provided. (ZWH)

Uses diagrams to aid in discussing how the English map of the human chromosomes, published by Offner in 1993, can be used to illustrate some important questions in evolution, as well as give students a glimpse into some of the mechanisms underlying evolutionary change. (ZWH)

Using the syllabus theme Insecta, strategies for implementing a holistic approach to teaching biology is described. This approach relies largely on self-activity, self-discovery, differentiation, and intrinsic motivation on the part of the student to enhance their learning experiences. (ZWH)

Describes historical accounts dating back to as early as 604-562 BC of the various uses of hydroponics. Throughout the article, diagrams and simple instructions are provided to aid in classroom use of hydroponics. (ZWH)

Students should have some experience with science carried out over time periods of several months or an entire school year. Presents suggestions to help teachers start their own bank of ideas for long-term science activities. (PR)

Presents detailed descriptions and diagrams for having students build their own hot air balloons. Describes the educational benefits of the balloon building. (PR)

Presents detailed descriptions and diagrams for having students build their own miniature box kites. Describes the educational benefits of the kite building. (PR)

Describes an integrated student-designed investigation in which students explore different aspects of the Chagrin River including the river ecosystem, velocity and average depth, river flooding, water quality, and economic and political factors. (JRH)

Presents an activity in which students attempt to keep water at a constant temperature. Helps students in grades three to six hone their skills in prediction, observation, measurement, data collection, graphing, data analysis, and communication. (JRH)

Describes a year-long process of inquiry and scientific learning with a class of fourth-grade students. Describes how the students observed, questioned, and wondered their way to new understandings of the life of birds and the nature of inquiry learning. (SR)
