This paper seeks to contribute new insight to the process of learning during idea generation (i.e., brainstorming) by proposing and evaluating two alternative operationalizations for learning, which we refer to as connection-based learning and multi-perspective learning, during a carefully designed idea-generation task in the earth-sciences…

"Science Learning and Instruction" describes advances in understanding the nature of science learning and their implications for the design of science instruction. The authors show how design patterns, design principles, and professional development opportunities coalesce to create and sustain effective instruction in each primary scientific…

Describes a simple activity designed to show the effects of leaching and evaporation on salts in the soil. (CP)

This is the second in a series of guidebooks written for elementary school teachers to help improve their science teaching. The book emphasizes processes of science and creativity as well as science content. The book is divided into three sections--the atmosphere, the lithosphere, and the hydrosphere. Each chapter begins with simple concepts, and…

The mixing of sediments by organisms (bioturbation) is discussed. Research techniques are discussed and data on Atlantic bioturbation rates are provided. (CP)

The investigations for topics 9-14 in the earth science course developed by The University of the State of New York for secondary schools are contained in this supplement to the syllabus (ED 046 749). The topics in this supplement include the erosional process, the depositional process, the formation of rocks, the dynamic crust, interpreting…

Describes activities by which the porosity and permeability of materials with respect to water can be measured. (CP)

This publication is one of a series of single-topic problem modules designed for use in undergraduate geology and earth science courses. The first section, "Ain't It Flat? A Series of Experiments in Geodesy," presents various experiments for determining the earth's circumference (historically) and describes the use of satellites in determining the…

This booklet describes the results of NASA's Viking spacecraft on Mars. It is intended to be useful for the teacher of basic courses in earth science, space science, astronomy, physics, or geology, but is also of interest to the well-informed layman. Topics include why we should study Mars, how the Viking spacecraft works, the winds of Mars, the…

Up-to-date knowledge about Skylab experiments is presented for the purpose of informing high school teachers about scientific research performed in orbit and enabling them to broaden their scope of material selection. The second volume emphasizes the sensing of earth resources. The content includes an introduction to the concept and historical…

Utilizing scientific processes to build a comprehensive background in the area of air, weather, and man's use and misuse of his environment is the goal of this student text. Basic information introduces each of the 22 chapters, followed by classroom or laboratory experiments when appropriate, review questions, and ideas for further investigations…
