Project-Enhanced learning is an excellent way to facilitate student-centered learning along with traditional lecture-based learning. In this Class and Home problem, an example of Project-Enhanced learning is provided that can be used in the Mass and Energy Balances (MEB) course. The students solve this problem as part of a group while receiving…

To incorporate active and collaborative teaching methods early in our curriculum, we have developed a freshman design laboratory. The course introduces numerous core concepts and lab skills, by way of seven teaching modules, including spectrometer construction and a collaborative project with seniors. Survey data show students enjoyed and learned…

Described is an experiment which uses an autotrophic bacterium to anaerobically oxidize hydrogen sulfide to sulfate in a batch-stirred tank reactor. Discusses background information, experimental procedure, and sample results of this activity. (CW)

Described is a project where students gain experience in handling large volumes of hazardous materials, process start up and shut down, equipment failures, operational variations, scaling up, equipment cleaning, and run-time scheduling while working in a modern pilot plant. Included are the system design, experimental procedures, and results. (KR)

An activity in which students obtain a growth curve for algae, identify the exponential and linear growth phases, and calculate the parameters which characterize both phases is described. The procedure, a list of required materials, experimental conditions, analytical technique, and a discussion of the interpretations of individual results are…

Describes a simple thermodynamics experiment recommended for use in beginning chemical engineering laboratory courses. Outlines the theory behind the experiment, which determines the specific heat of a liquid. Discusses the construction, operation, and maintenance of the apparatus involved, along with the experimental procedure. (TW)

Described is a laboratory in which students are confronted with rigs built from full-sized industrial machinery and equipment. Students must draw a flow sheet, dismantle and draw key components, reassemble the parts, operate the rig, and interpret the run data. The laboratory and the course built around it are discussed. (KR)

Follows the increase of the pH in a solution of vinegar during neutralization with commercial antacid tablets. Provided are background information, equipment details, procedures, and details of the data analysis. (MVL)

Described is a membrane experiment that provides students with experience in fundamental engineering skills such as mass balances, modeling, and using the computer as a research tool. Included are the experimental design, theory, method of solution, sample calculations, and conclusions. (KR)

Focuses on the development of a pilot unit for use in an advanced separations process laboratory in an effort to develop experiments on such processes as reverse osmosis, ultrafiltration, adsorption, and chromatography. Discusses reverse osmosis principles, the experimental system design, and some experimental studies. (TW)

Describes an experiment developed and used in the unit operations laboratory course at the University of Wyoming. Involves the liquid-phase adsorption of an organic compound from aqueous solution on activated carbon, and is relevant to adsorption processes in general. (TW)

Described is a reliable and predictable laboratory experiment which represents the result of an integrated approach to design with an emphasis on teaching. Notes the flat-celled rig has logged over 100 hours service in 2 years without any problems. (MVL)

Discussed are problems encountered when a gas absorption experiment with strong measurement error is used. Notes students either avoid the experiment or report it as defective. Provides ideas to make lab experiments more instructive. (MVL)
