Discusses a new program at the University of Michigan in hazardous waste management. Describes a laboratory demonstration that deals with the reactivity and potential violence of several reactions that may be encountered on a hazardous waste site. Provides criteria for selecting particular compatibility testing methods. (TW)

Describes apparatus for use in high school chemistry instruction. Provides instructions and lists of materials needed for building a homemade sand bath for use in experiments that demonstrate the slow evaporation of a solvent. Plans for the construction of a low-cost conductivity apparatus are also included. (TW)

Nearly 100 teachers worked with staff members at the Exploratorium museum in San Francisco, California, to create scaled-down versions of Exploratorium exhibits that teachers could make on their own using common, inexpensive, readily-available materials. The experiments--called "snacks"--are divided into easy-to-follow sections that…

Developed by classroom teachers during the development phase of Minnesota's Graduation Standards, this performance package is made up of locally designed assignments that, taken together, show whether a student has learned and can apply the knowledge and skills related to comprehending technical information from documents or electronic media and…

"How Students Learn: Science in the Classroom" builds on the discoveries detailed in the best-selling "How People Learn." Now these findings are presented in a way that teachers can use immediately, to revitalize their work in the classroom for even greater effectiveness. Organized for utility, the book explores how the principles of learning can…

Presents two examples of laboratory exercises using the World Wide Web for first-year medical students. The first example introduces the physical laws that apply to osmotic, chemical, and electrical gradients and a simulation of the ability of the sodium-potassium pump to establish chemical gradients and maintain cell volume. The second module…

Describes a unit that applies constructivist teaching methods to a science concept. Contains mini-lessons in math that present to students information that they need to know in order to perform their experiments. Gives students the opportunity to construct their own knowledge about the natural phenomenon of light as they apply their mathematical…

Described are some commonly encountered chemistry experiments that have been modified for computerized data acquisition. Included are exercises in radioactivity, titration, calorimetry, kinetics, and electrochemistry. Software considerations and laboratory procedures are discussed. (CW)

Advocated is the use of interactive centers to supplement existing classroom laboratory experiences. Activities found in the center and modified classroom versions are described. The problems that arise when primary students meet sophisticated exhibits is discussed. (KR)

Discussed are the advantages and processes of making collections with children. An activity for making a classroom collection (herbarium folios) is described and includes materials and procedures. The processes of collecting and classifying are stressed. (CW)

Presents an activity that models the changes in the concentration of carbon dioxide gas in the atmosphere during the last 200 years as determined from glacial records. (PR)

A new classification of rocks that requires no tools other than a hand lens and that is both comprehensive and informative is described. Each of the three main rock groups is treated in two-dimensional, rectangular charts with additional appended boxes that provide optional mineralogical and textural terms that can be used in rock names. (PR)

Describes an activity where students generate a plan and test their ideas on trying to cope with a small oil spill. (PR)

This packet contains four science learning activities that can be used in agricultural education courses. The activities cover these topics: (1) determining the effect of air pressure on fluid flow; (2) how lubrication and oil viscosity affect friction; (3) determining relative strengths of wood fasteners; and (4) determining the effects of…

The Zimbabwe Secondary School Science Project (ZIM-SCI) developed student study guides, corresponding teaching guides, and science kits for a low-cost science course which could be taught during the first 2 years of secondary school without the aid of qualified teachers and conventional laboratories. This teaching guide, designed to be read in…
