This manual is part of a series of materials designed to reinforce essential concepts in physical science through interactive, language-sensitive, problem-solving exercises emphasizing cooperative learning. The manual is intended for limited-English-proficient (LEP) students in beginning physical science classes. The materials are for teams of two…

The goal of this activity is to solve problems encountered when preparing food for space flight. Includes student worksheets. (MKR)

A brief introduction to the broad field of curve-fitting is provided to help explain the reasoning behind least-squares data fitting, and also to provide useful equations for two functional forms of interest in chemistry. Appendices give program examples written in Fortran and detail the method of Guggenheim. (MP)

Provides a list of 33 problem-solving steps extracted from physics textbooks and arranged within the following 3 categories: setup, solution, and checks. (MDH)

This book contains hands-on science laboratory activities for grades 4 through 9 that use discrepant events to challenge students. All of the "puzzlers" are based upon science principles and include directions for building gadgets that explain the "puzzlers." Topics covered include: volume conservation, magnetic phenomena,…

Contains suggestions for students regarding making up nicknames for animals based on their observations. Also includes information about the overpopulation of pets and urges students to write letters to their newspaper editors about this problem. A sample letter is provided. (TW)

The case-based study, which presents students with a dilemma that encourages exploration, is becoming a popular method for teaching biology. This Web-based report offers one such case study that asks readers to solve problems and make decisions based on information gathered as they engage with characters or situations in the story. The basis for…

This article is a reproducible page for students in grades four through six. The stated objective is the student will organize information about unfamiliar animals and infer other information. Students read clues about five newly discovered species and use a chart to organize this information in a more meaningful way. (PR)

Presented is the learner's guide for a high school level independent study course in environmental studies. The manual is divided into two sections: (1) The Nature of the Environment, with lessons on ecosystems, limiting factors, interdependence and adaptation; and (2) Economic, Political, Behavioral, and Ethical Aspects of Environmental Studies,…

Models of the motion of an object through space are discussed. The material begins with the simplest view possible in which gravity is the only force examined. Discussion progresses to an examination of the drag force, which is the resistive air force of the wind. Suggestions for further improvements are made at the conclusion of the presentation.…

Describes the importance of estimation in science for planning projects, conducting experiments, and developing theories. Defines order of magnitude. Provides explicit mathematical equations and calculations to estimate answers for seven provocative physics problems. Includes nine additional open-ended problems with hints and solutions. (PR)

Resources that will help secondary students become more effective problem solvers are provided. The book describes techniques or tools and an overall strategy for solving problems. Throughout the book there are exercises that enable the student to practice the techniques. The first chapter provides an overview of the problem solving process.…
