Seven activities are included in this 10 day secondary school science unit in which students determine the effect that auto exhaust fumes have on the air they breathe by utilizing laboratory experiences, independent research, and in-class discussions. Rationale, objectives, and instructional strategies are provided for each activity. Following two…

The major objective of this module is to help students understand how water from a source such as a lake is treated to make it fit to drink. The module, consisting of five major activities and a test, is patterned after Individualized Science Instructional System (ISIS) modules. The first activity (Planning) consists of a brief introduction and a…

This report presents the methodology and findings of a national survey of the performance of approximately 9,000 11-year-old children in science. Performance was assessed in six categories: (1) symbolic representation (reading information from graphs, tables, and charts); (2) use of apparatus and measuring instruments; (3) observation; (4)…

Listed in this science syllabus are concepts and understandings in five areas of astronomy (earth, studying the heavens, earth's moon, the sun and other stars, and the solar system) and two areas of aerospace science (flight in air and flight in space). Included with these The booklet also includes questions for students to answer and, when…

Since the major causes of accidents are carelessness and a negative or apathetic attitude towards safety, this guide was developed to facilitate safe, stimulating science laboratory activities by providing both general and specific safety information presented in 12 sections. Subject areas considered in these sections include: 1)…

"Science for the Seventies" (SFTS) is designed to aid teachers and administrators by helping them select materials from available elementary science programs, modify on-going science programs, or develop a better science curriculum. SFTS encompasses 16 televised programs which provide introductory experiences appropriate for launching a…

Construction of laboratory equipment from earthenware clay uses art as a way to incorporate the element of science history into an Introductory Physical Science (IPS) unit on distillation. Classroom techniques for working with clay to construct distilling apparatus are outlined. Other supplementary material from the arts, including slide…

Describes a simple thermodynamics experiment recommended for use in beginning chemical engineering laboratory courses. Outlines the theory behind the experiment, which determines the specific heat of a liquid. Discusses the construction, operation, and maintenance of the apparatus involved, along with the experimental procedure. (TW)

Contains 31 activities and experiments from the biological and physical sciences. Addresses such areas as reproduction, biotechnology, ecology, proteins, nitrates, aerosols, metal crystallinity, circuit boards, and photoswitching. (ML)

Provides suggestions for two exercises designed to assist and involve students in understanding chemical concepts. Includes a laboratory experiment for determining the Ksp of a saturated solution of calcium sulfate and a scheme for naming oxyacids and their salts. (ML)

Presents as part I of a two-part series a study involving the intercellular transfer of bacterial DNA that codes for the resistance to antibiotics. Demonstrates to students that such transfers occur. Discusses laboratory procedures, materials and results. (CW)

Describes two experiments for demonstrating the properties of osmosis and semipermeable membranes. Gaseous and liquid osmosis are studied through the use of common laboratory chemicals and equipment. Offers explanations for the phenomena with diagrams. (ML)

Demonstrates a method of measuring the acceleration due to gravity. Provides an illustration of the apparatus and the data analysis. Suggests four different variations of this experiment. (YP)

Discusses the need for student research-type chemistry projects based upon "unknown" metal complexes. Describes an experiment involving the product from the reaction between cobalt(II) chloride, ethane-1,2-diamine (en) and concentrated hydrochloric acid. Outlines the preparation of the cobalt complex, along with procedure, results and…
