This storybook discusses the concepts of matter, energy, life, and time. The ideas of ecology, natural resources, and recycling are presented in a format which can be easily read by elementary school students. (CW)

Cognitive and affective outcomes of class visits to two participatory science museums were examined by comparing responses of fifth- and sixth-grade students randomly assigned to four conditions (control, exhibit only, lesson only, and exhibit followed by lesson) and two tests (verbal and visual). Students visiting a simple machines exhibit scored…

The article outlines an activity for providing a hands-on opportunity for elementary and middle school science students to study the theory of the earth's crustal change over the past several hundred million years. The theory of continents drifting away from one super continent is presented with the supportive evidence that scientists have…

The purpose of this study was to determine the level of reasoning of a convenience sample of all seventh through twelfth grade students (N=156) in a consolidated school district in rural Arkansas prior to the introduction of a thinking program in which logical thinking is one component. Four research questions were investigated: (1) What…

This practicum addressed the problem of decreased participation of fifth-grade students in the science fair. At this grade level, the science fair guidelines mandate that students enter a research-type project. For many fifth-grade students the desire to tackle this monumental task does not match their developing cognitive skills. The literature…

This study examined the effect of formal and concrete instruction upon science achievement and intellectual development of sixth grade students. Formal instruction, which emphasized oral and written language, included lecture, discussion, oral quizzes, written assignments, reading assignments, films, film strips, written tests, and quizzes.…

This educational packet consists of an overview, three lesson plans, student data sheets, and a poster. The overview examines estuaries and tidal or salt marshes by discussing the plants and animals in these habitats, marsh productivity, benefits and management of the habitats, historical aspects, and development and pollution. A glossary and list…

Presented are seven articles (reprinted from "The Exploratorium" magazine) which focus on the scientific explanations for the specific (and oftentimes peculiar) instructions and procedures called for in many recipes. "Baking, Boiling, and Other Hot Topics" (Joel Myerson) discusses different methods of cooking. "The…

The materials in this educational packet are designed for use with students in grades 4 through 7. They consist of an overview, teaching guides and student data sheets for three activities, and a poster. The overview discusses why, how, where, and when birds migrate as well as problems birds encounter while migrating; the importance of research…

This workbook contains 47 activities and exercises which reinforce lesson topics found in the grade 3 science textbook. These lesson topics, presented in nine sections in the textbook, focus on such areas as: (1) solar energy, electricity, and light; (2) solar system, planets, earth motions, and phases of the moon; (3) gravity, rocks, and erosion;…

This study examined the relationships between cognitive development, language acquisition, and socioeconomic class, as manifested in children's written language. Four classes of sixth-grade students participated in the investigation, a control class and an experimental class from each of two socioeconomic environments (low and high). The treatment…

Presented is a compendium of activities and reference materials in environmental education and energy education that was developed by participants in a year-long institute conducted by Tennessee Technological University and sponsored by the National Science Foundation. The manual is divided into three sections. The first consists of 111…

This environmental unit is one of a series designed for integration within an existing curriculum. The unit is self-contained and requires minimal teacher preparation. The philosophy of this series is based on an experience-oriented process that encourages self-paced independent student work. The purpose of this particular unit is to prove that…
