To expertly solve engineering and science problems one needs to know science and engineering as well as have a tool kit of problem-solving methods. This book is about problem-solving methods: it presents the methods professional problem solvers use, explains why these methods have evolved, and shows how a student can make these methods his/her…

Uses the context of rock climbing to discuss the science concept of friction. Presents the mathematics equations that describe the concept. Examines the physics of different rock climbing situations encountered and equipment used. A series of related problems with answers is provided. (MDH)

Two computer-generated star charts that can be used as overlay transparencies to show an expanding universe are presented. Directions on how to use the star charts to determine the Hubble constant and the age of the universe are provided. (KR)

A method for demonstrating eutrophication that can be used as a simple illustration of the phenomenon or as a basis for problem-solving activities is presented. A sample worksheet with procedures for this activity and discussion questions is included. (Author/KR)

An activity in which students use a rubber band and flexible straws to pull a dynamics cart so that the cart has a consistent angle and, therefore, a consistent horizontal component of force is described. A copy of the handout for the activity is included. (KR)

This teacher's guide contains activity modules designed to help explain present energy use patterns and basic concepts in energy use. Also covered in the manual are suggestions for energy-related field trips and strategies for successfully conducting such trips. The activities are presented according to grade level, including primary,…

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

Slope Stability is one in a series of single-topic problem modules intended for use in undergraduate and earth science courses. The module, also appropriate for use in undergraduate civil engineering and engineering geology courses, is a self-standing introduction to studies of slope stability. It has been designed to supplement standard…

This unit describes four secondary school activities related to the geography of the Great Lakes. In Activity A students develop map skills as they study the lakes' positions and associated cities; these skills are applied to the St. Lawrence Seaway in Activity B. Activities C and D involve learners in solving perimeter, area, distance, rate,…

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 are six modules designed to help junior high school students develop the skills needed to study and take action with respect to environmental problems. The first five modules cover basic investigation skills: identifying environmental problems, using secondary sources, conducting surveys, interpreting data, and studying environmental…

Presents six learning activities dealing with planetary motion, the launching of satellites, and Halley's comet, all of which utilize the three laws of Johannes Kepler. These three laws are discussed in detail, and answers to the activities are provided. (KR)

The relationship between specific gravity, salinity, and density in brine solutions is investigated. Students construct hydrometers to reinforce concepts learned in oceanography. Background information, salt requirements for the unknowns, directions, and reproducible worksheets are included. (KR)

This is the second sourcebook that has been produced by members of the Council of Elementary Science International (CESI) in cooperation with the ERIC Clearinghouse for Science, Mathematics, and Environmental Education. This sourcebook is focused on activities designed to enhance children's thinking. Activities emphasizing creativity,…

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)
