Describes an application of solid-state memories in a laboratory course, which enables students to build electronic devices. Also introduces the fundamentals of analog-to-digital conversion and sampling theory. (CS)

Summarizes the advantages in using the Daedalon Air Table, which supplies compressed air to the pucks instead of the table surface itself. Describes methods for constructing an electronic null detector using a Weston type galvanometer and an integrated circuit operational amplifier. Also describes a redesigned and improved sound-level meter. (CS)

Since the major causes of accidents are carelessness and a negative or apathetic attitude towards safety, this guide was developed to facilitate safe, stimulating science laboratory activities by providing both general and specific safety information presented in 12 sections. Subject areas considered in these sections include: 1)…

Discusses and lists, in table form, the specifications and characteristics of 28 low-cost digital multimeters, including jacks, number of V ranges, max V, cost, approximate percent accuracy, current scales, display, battery life, volume, and manufacturers. Quality of construction, ease of repair, and similar characteristics not reported. (SK)

Outlines several laboratory procedures and demonstrations including electric fields using sawdust, experiments with capacitors, particle spacing in a vapor and a liquid, metrology, momentum, Moire patterns and interference fringes, equipping for practical electronics, and using programmable calculators for rapid plotting of graphs.
