Uses alkaline phosphate to remove the phosphate group from phenolphthalein diphosphate. Discusses problems which include the interference of ambient light and temperature variation. Provides detailed information about the apparatus and the experimental procedure. (ASK)

This book is part of the series "Explorations in Science" which contains enrichment activities for the general science curriculum. Each book in the series contains innovative and traditional projects for both the bright and average, the self-motivated, and those who find activity motivating. Each activity is self-contained and provides everything…

This document provides biology experiments designed for students who have completed a first year biology course. This self contained laboratory booklet contains four sections. In section 1, "Instrumentation in the Study of Cells," discussion sections and suggestions for teacher demonstrations are provided. It also includes some basic materials…

States the procedure for isolating actinomycetes from soil and testing for antibiotic growth. (LS)

This booklet discusses some of the basic facts about nuclear energy and provides eight experiments related to these facts. The experiments (which include lists of materials needed and procedures used) involve: (1) an oil-drop model of a splitting atom; (2) a domino model of a chain reaction; (3) observing radioactivity with an electroscope; (4)…

Describes some of the scientific experiments of Joseph Henry, his role as a scientist and an educator, his contributions to physics teaching both at the precollege and college levels. (GA)

Two physics experiments are described, One, involving a laboratory cart accelerated along a level surface, examines the concept of inertial mass in translation and the other, using a solid cylinder, measures the moment of inertia of a wheel. Equations and illustrations are included. (MA)

The mini-course offers unusual opportunities for teachers and schools that wish to experiment with new forms. Certain very significant characteristics have to be present in order for the mini-course to be productive and eight important ingredients are listed here. (Author/RK)

Discusses limitations and corrections to be made in physics experiments involving the investigations of drag and terminal velocity on spheres falling through a liquid in accordance with Stokes' law. (SL)

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

Describes how to make an electroscope from aluminum soft drink or beer cans. Also describes several electrostatic experiments using the easily constructed apparatus. (JN)

Describes some laboratory projects to enable high school students to learn about bromelin, a protein-digesting enzyme. (PS)

Describes laboratory activities using algae as the organisms of choice. These include examination of typical algal cells, demonstration of alternation of generations, sexual reproduction in Oedogonium, demonstration of phototaxis, effect of nitrate concentration on Ankistrodesmus, and study of competition between two algae in the same environment.…

Describes the collection and culturing of microscopic molds that feed mainly on tiny nematodes in the soil. Includes bibliography. (MA)
