Presents activities that explore step-cut dissections of whole rectangles. Provides students with the opportunity to discover patterns, which allows them to solve more and more complex problems that offer a context within which students can think about and use different mathematical concepts. (JRH)

Presents activities that use the learning cycle to engage students in meaningful inquiries in the study of Mendelian genetics. Includes content-related background and teaching tips for each phase of the learning cycle. (JRH)

This publication is designed for both classroom teachers and nonformal educators of young people in grades 6 through 12. It can provide a 6- to 8-week course of study on the watershed with students participating in activities as they are ordered in the guide, or activities may be used in any order with educators selecting those appropriate for the…

The pocket-sized guide book is intended for law enforcement and land management agencies responsible for land-based search and rescue missions and is also useful for outdoor leaders. The information in the book is based on two premises, that a search is an emergency situation and that a search is a classic mystery. The guidebook contains…

Fieldwork provides an opportunity to reinforce previous class-based learning and presents students with an opportunity to encounter new ideas and practice new skills. In the K-12 classroom, however, the rhetoric-reality gap between the declared need for fieldwork and doing fieldwork is striking. This project seeks to narrow the gap between…

Although traditional instructional methods and textbooks mitigate against it, investigation can be a viable alternative strategy in the geometry classroom. Many theorems in geometry, such as Euclidean space, lend themselves easily to student experimentation. (Author/SJL)

Describes a project that uses a multidisciplinary approach to problem solving in analyzing a crime scene and suspect evidence. Requires each student to work effectively in a team, communicate in both written and oral forms, perform hands-on laboratory manipulations, and realize that the entire class was depending on their individual contributions…

Discusses ideas for water rocket investigations. Highlights safety precautions that should be considered when using water rockets with soda bottles. (JRH)

Describes the experiences of children in a program that highlights the process of inquiry by allowing and encouraging children to raise questions, develop investigation strategies, formulate theories, and report findings in a variety of ways. Discusses the teacher's role in observing, respecting, and supporting children's work. (JRH)

Described is a third-grade science unit using feathers. Children use the feathers to learn about measurement, observation, and inference. Procedures and results are discussed. (CW)

Explains how a school developed a model for ensuring progression in experimental and investigative science. Provides progression steps and examples of models. (CCM)

Presents examples of the types of investigations which exploit the tools now commonly featured in data-logging software. Emphasizes the importance of designing tasks that encourage pupils to think about the data and the principles which underpin worthwhile data-logging tasks. (Author/ASK)

Describes nine basic experiments that demonstrate the wave nature of light and the optical properties of water. Finds that a laser pointer works well as a light source in the laboratory. (CCM)

The theme of Scale and Structure (or simply Scale) appears in many state science frameworks and projects of national importance. The major idea of this theme is that a change in scale will affect the nature of the given structure. This book is designed as a guide and set of activities for third- through eighth-grade teachers. The activities…

This project is designed to engage students in investigating specific environmental problems through concrete activities and direct experiences. In doing so, it fosters an awareness of the importance of informed concern about environmental issues.
