An assessment of the progress of the regional educational laboratories created under Title IV of the 1966 Elementary and Secondary Education Act. Specific information on 12 laboratories is included. (AP)

Describes a "flat" linear air track, glider and spark timer system for use in the physics laboratory. The results of experimental tests using the system are briefly stated. (SA)

Information is given on the basic chemistry of fire and on the characteristics of flammable liquids. (BB)

Describes a laboratory exercise containing a practical series of experiments that novice students can perform within two hours. The exercise provides a confirmation of van't Hoff's law while placing more emphasis on osmotic flow than pressure. Students can determine parameters such as the reflection coefficient which stress the interaction of both…

Recommends some measures to take to ensure that demonstrations are carried out safely. Includes a sample checklist to be completed before and after demonstrations. (DDR)

Explains how to maintain biosafety in high school level biotechnology and microbiology courses. Focuses on laboratory skills, biohazard containment, and defense perimeters. (YDS)

Presents the script of a skit designed to engage beginning students in a contest to identify and list the most safety violations they observe during the skit. Includes a list of 37 safe laboratory practices. (MKR)

Reports the use of a heavy duty hacksaw blade and a 1000 turn pick-up coil to form the basis of a mechanical oscillator for a laboratory exercise in mechanical resonance designed for either the elementary undergraduate course or in association with an upper level mechanics course. (LZ)
