Describes an activity comparing incandescent bulbs and LEDs powered by dc and ac voltage sources to illustrate properties of matter and the interactions of energy and matter. Includes both instructor information and student activity sheet. (Author/YDS)

Explains how to use galvanotaxis and mutagenesis experiments to study Paramecium's swimming behaviors and ion channel functions. (YDS)

Presents demonstrations of chemical reactions by employing different features of various compounds that can be altered after a chemical change occurs. Experimental activities include para- and dia-magnetism in chemical reactions, aluminum reaction with base, reaction of acid with carbonates, use of electrochemical cells for demonstrating chemical…

Presents a laboratory exercise that allows students to investigate the principles of hormone release from endocrine cells, which is highly relevant to students' everyday lives. (Contains 17 references.) (ASK)

Describes a laboratory experiment in which students identify 11 white solids readily available in drugstores and supermarkets. Investigates solubility, pH, copper reduction, evolution of carbon dioxide bubbles, formation of starch-iodine complex, and formation of an insoluble hydroxide. (YDS)

A laboratory activity that can be used at a number of levels from high school to college is discussed. This activity can be used to teach chemical concepts such as oxidation and reduction, stoichiometry, acids and bases, pH, nucleophilic reactions, conjugation, leaving groups, complexation, solubility, and reversibility.

Science projects which can be used by high school students who have minimal experience with computers or electronics are presented in this book on laboratory interfacing. These laboratory interfacing projects include either the connecting of measuring instruments directly to a computer or using a computer to control external devices. All of the 14…

This sourcebook for chemical activities is designed to be used as a student laboratory book for both junior and senior high school students. The student's role as a knowledgeable consumer and informed citizen is stressed. Each activity includes a list of needed materials, procedures, reactions, questions, and notes for the teacher which include…

This book provides laboratory experiments to enhance any food science/botany curriculum. Chapter 1, "Introduction," presents a survey of the techniques used in plant biotechnology laboratory procedures. Chapter 2, "Micronutrition," discusses media and nutritional requirements for tissue culture studies. Chapter 3, "Sterile Seeds," focuses on the…

Explains the techniques of experimenting with the protozoan Colpoda cucullus to learn about its habitats, dispersal and adaptations. (LS)

Describes an experiment that gives useful insight into ideas of solvation and polarity of solvents. (GS)
