Introduces an inquiry-based laboratory experiment in which students identify an unknown bacterial species by using techniques such as Gram staining. Uses an authentic problem solving approach in a scenario entitled, "What poisoned the apple juice?" (YDS)

This publication is intended to be a resource for teachers and administrators who are responsible for the safety of students, and others, in the general areas where science instructing is occurring. The handbook is designed to assist teachers of science regardless of their background in science. Particular concerns such as laboratory safety…

The trend toward inquiry-based learning is providing today's students with a more enriching education. When implementing inquiry it is important to recognize the great number of safety concerns that accompany this paradigm shift. Fortunately, with some consideration, teachers can shape students' laboratory experiments into safe and valuable…

An environment appropriate for activity-oriented science is one that contains sufficient work space, equipment, and materials for students to practice and master the essential elements. This publication was developed to aid Texas school administrators, teachers, and architects to upgrade existing science facilities or plan new ones for…

This guide is designed to assist teachers in involving students in individual or small group laboratory investigative experiences in the life sciences. Each of the 22 experiments contains a prelab and postlab section for teachers and a detailed procedures section for students. (Author/CO)

This document describes ways to work with DNA and host organisms in precollege classrooms. The guidelines are intended to assist the teacher who already has training in working with microbes, DNA, and associated chemicals. The contents of the guidelines include: (1) Permitted DNA molecules, vectors, and recommended host organisms for constructing…

Describes procedures for two demonstrations: (1) photochemical energy conversion using ferric oxalate actinometry and (2) liquification of gases using Freon 114. Safety precautions are given for both demonstrations, as are procedures and material specifications. (JM)

Discussed are the potential hazards associated with nitric acid, inorganic and organic nitrate salts, alkyl nitrates, acyl nitrates, aliphatic nitro compounds, aromatic nitro compounds, and nitration reactions. (CW)

Lab safety begins with the teacher. Teachers must make learning how to be safe an integral and important part of their professional development and work. Teachers who are unfamiliar with laboratory instruction should take whatever steps necessary to prepare for the unique challenges associated with safety in conducting laboratory investigations…

The problems involved when radiation-producing devices of our contemporary technology are used in the teaching of science at the high school and undergraduate college level are discussed. Information is provided on the hazards involved in the use of radiation-producing equipment or radioactive materials in science demonstrations and experiments…

This handbook is based on a list of essential topics that should be mastered by the student who subsequently plans to pursue college chemistry. Chapters include: (1) "Introduction" (describing a position paper and the background of the handbook); (2) "Essential General Topics and Objectives"; (3) "Testing Students"…

Designed for high school science teachers, the document warns of potential health threats of performing certain experiments and using certain chemicals or chemical combinations in their courses. Following a rationale for more carefully considering health dangers, the document gives suggestions on what can be done by teachers. Reports such as a…

Describes the use and handling of alkali metals in school laboratories and seeks to reexamine precautions which one may reasonably take before executing routine procedures since their use, even by skillful teachers, occasionally results in accidents in the form of violent explosions. (Author/SK)

Notes that this experiment takes safety and noncarcinogenic reactants into account. Demonstrates the use of diazonium salts for the replacement of an aromatic amine group by a phenolic hydroxyl. Involves two pleasant-smelling organic compounds, methyl anthranilate (grape) and methyl salicylate (oil of wintergreen). (MVL)
