Describes a series of activities designed to help students understand the dynamics of flowing water. Includes investigations into determining water discharge, calculating variable velocities, utilizing flood formulas, graphing stream profiles, and learning about the water cycle. (TW)

Determined which of 10 rational thinking powers are measured by 12 commercially-available standardized science tests. One result reported is that 90 percent of the test items required only recall. The conclusion was drawn that the producers of standardized tests are not concerned with measuring student achievement of the rational powers.…

Highlights a workshop utilizing a four-volume sourcebook for K-12 science teachers and naturalists. The volumes contain 38 units focusing on land, water, atmosphere and weather, plants, animals, energy, natural ecosystems, urban areas, unusual and rare features, and problems and issues. A sample interdisciplinary activity on bullfrog development…

Results of this study confirm discrimination of the intensive time-series design and indicate that it can be used to distinguish differences in learning (comprehension and knowledge) between eighth-grade earth science students (N=95) having formal cognitive tendencies and those having concrete cognitive tendencies.

Whether you're a stream studies novice or a veteran aquatic monitor, "Watershed Dynamics" gives you abundant practical resources to extend your students' investigations into local water quality and land-use issues. This two-part set is ideal for teaching biological and ecological concepts and research techniques. It also shows how the interplay…

Get students into math using outer space! Mission Mathematics translates the NASA experience into language and experiences appropriate for young learners, and provides teachers with mathematics activities that complement many of the available NASA resources for students and educators. In these motivating investigations, young children engage in…

This book is designed for middle school students to learn scientific literacy through event-based science. Unlike traditional curricula, the event-based earth science module is a student-centered, interdisciplinary, inquiry-oriented program that emphasizes cooperative learning, teamwork, independent research, hands-on investigations, and…

This book is designed for middle school earth science teachers to help their students learn about problems with hurricanes and scientific literacy through event-based science. Unlike traditional curricula, the event-based earth science module is a student-centered, interdisciplinary, inquiry-oriented program that emphasizes cooperative learning,…

The purpose of this book is to suggest an alternative approach to the teaching of elementary science in light of more contemporary definitions of both reading and science. This method utilizes well-selected and conceptually and factually correct works of narrative children's literature. Although the method is most easily applied with picture books…

This 23-minute videotape gives children (grades K-4) a close-up look at what makes the third planet from the sun so special. The answers to the following questions are discussed: (1) Why is there life on Earth? (2) What is our planet made of? and (3) How does the Earth fit into the rest of the universe? A hands-on activity that describes how to…

The videos in this educational series, for grades 4-7, help students understand the science behind weather phenomena through dramatic live-action footage, vivid animated graphics, detailed weather maps, and hands-on experiments. This episode (23 minutes) gives concise explanations of the various types of precipitation and describes how the water…

The videos in this educational series, for grades 4-7, help students understand the science behind weather phenomena through dramatic live-action footage, vivid animated graphics, detailed weather maps, and hands-on experiments. This episode (23 minutes) discusses how clouds form, the different types of clouds, and the important role they play in…

Field studies are a primary means of obtaining scientific knowledge about earth science concepts. This paper discusses why a teacher might choose a field trip as an educational strategy important to the teaching and learning of earth science. Reasons to choose field trips as a teaching strategy, factors that influence learning on a field trip, and…

This book consists of two complete units on soil. The first unit is created for lower elementary students and the second one is for upper elementary grade levels. The units are designed for gifted students and encourage students to be responsible for their own education. Each unit is based on an interdisciplinary approach. Suggestions for…

Discusses how the earth is a dynamic system that maintains itself in a steady state. Areas considered include large/small-scale earth motions, geologic time, rock and hydrologic cycles, and other aspects dealing with the changing face of the earth. (JN)
