Describes a semester-long project in which students designed, built, and operated an apparatus to separate particles by fluidization principles. Each laboratory group worked on a separate step of the design in a sequence selected by the instructor in a manner similar to the way a design team might function. (JN)

Describes a drying experiment useful in presenting the concept of simultaneous heat and mass transfer. Background information, equipment requirements, experimental procedures, and results are provided. The reasonably good agreement in the calculated rate of drying and that observed experimentally makes students feel confident in applying…

A number of classroom aids are described and sources given. Included are microscopes, films, minicomputers, balances, catalogs, and information bulletins. (RH)

Discusses the designs for an inexpensive table for analytical balances, a safety pipet for reagents, and permanent models for determining absolute configurations. (MLH)

Describes experiments that utilize unsophisticated equipment to measure the elastic constants of thin flexible strips of material. The attainable accuracy is limited by the measurement of the material's thickness. (MLH)

The universities and institutions that deal with undergraduate education generally have a traditional organizational structure: their human resources are allocated to departments which are structured on subjects, and the persons are grouped according to their specialization profile. As a result of this, it has been observed that many groups are…

Several suggestions are made for using empty duplicating fluid containers in science experiments and activities. (JR)

Describes responsibilities of travelling director in terms of teacher training, language laboratory maintenance, and audio skills and audio reference. (RL)
