Project WET (Water Education for Teachers) is a nonprofit water education program for educators and young people. This curriculum and activity guide for kindergarten through twelfth grades is a collection of innovative, water-related activities that are hands-on, easy to use, and fun. The activities incorporate a variety of formats such as large…

This book consists of four sections: (1) "Supplemental Materials"; (2) "Supplemental Investigations"; (3) "Test Item Bank"; and (4) "Blackline Masters." The first section provides additional background material related to selected chapters and investigations in the student book. Included are a periodic table…

Describes methods to redevelop lab activities for use in schools with limited resources for proper facilities and equipment. Discusses take-home labs, paper-and-pencil labs, and lab station activities. (JRH)

Examines the phenomenon of water drops that float on water at room temperature. Describes experiments that have been done to study this phenomenon. (MA)

Presents seven notes on new equipment, techniques, or materials of interest to teachers of physics. A circuit of a low-cost computer terminal to audiovisual device interface, and a demonstration of the buoyancy of air are among notes presented. (HM)

Presents nine physics notes for British secondary school teachers. Some of these notes are: (1) speed of sound in a steel rod; (2) physics extracts-part four (1978); and (3) a graphical approach to acceleration. (HM)

Describes some undergraduate laboratory experiments in acoustics which involve the analysis of speech and musical instrument sounds and the general analysis of the frequency range of complex sounds. (HM)

The standard addition titration is a precise and rapid method for the determination of the acidity in rain or snow samples. The method requires use of a standard buret, a pH meter, and Gran's plot to determine the equivalence point. Experimental procedures used and typical results obtained are presented. (JN)

Presents the following three biology notes: (1) a low cost variable temperature incubator; (2) projects on the ecology of freshwater mussels (Unionidae); and (3) studies on urease. (HM)

Presents 12 chemistry notes for British secondary school teachers. Some of these notes are: (1) a simple device for testing pH-meters; (2) portable fume cupboard safety screen; and (3) Mass spectroscopy-analysis of a mass peak. (HM)

Presents six middle school science notes for British science teachers. Some of these notes are: (1) fingerprints; (2) the floating magnet; and (3) the production of electricity using a lemon. (HM)

Describes a biochemistry class project which allows students to investigate independently the separate aspects of a common complex problem. The basic experimental procedure is detailed for obtaining information about the structure and geometry of L-ornithine carbamoyltransferase. (CS)

Describes an experiment which makes use of a number of concepts from geometrical optics. The apparatus and method which is intended for students in elementary college physics classes are included. (HM)

The rhizosphere is the area directly surrounding the roots of a plant and an area of tremendous microbial growth. This article described techniques for studying this soil biome. Illustrations are included. (MA)

Contains a reading list of articles published in 1985 covering 14 biological topics. Includes descriptions, procedures, and references for 26 experiments. These investigations deal with selected concepts in biology, ecology, chemistry, and physics and include computer-based instruction. (ML)
