Undergraduate Laboratory

Undergraduate laboratory exercises in core engineering courses do not always subscribe to the Problem Based Learning approaches advocated by the educational community [1–3]. Common shortcomings include “cookie cutter” labs where students are not engaged in experimental design as well as a general detachment from the “real world” application of the laboratory exercise. Soft skills like proper documentation during experiments as well as scientific writing may also be overlooked in lab curricula. This is unfortunate, as the undergraduate laboratory experience is a perfect opportunity to develop essential research skills as well as inspire and excite students about their chosen field.

Whole Plants

A tissue culture laboratory exercise illustrating regeneration of whole plants from leaf segments of chrysanthemum by organogenesis is described. Using simple, common media, shoots can be generated in 5 weeks and rooted after an additional 3 weeks. Acclimatization of plants can be accomplished in a simple mistbed in the greenhouse. The exercise is adaptable to depict genotype differences among cultivars, optimization of shoot induction, effects of growth regulators, and experimental design. Callus is typically not formed during shoot formation; however, co-cultivation of leaf segments with a virulent strain of Agrobacterium tumefaciens produces callus with a strain of disarmed A. tumefaciens harboring NPTII construct affects regeneration of plants resistant to kanamycin.

Main Components

The formation of scales in pipes and on the surfaces of vessels is one of the major problems encountered by the mineral processing industry in Australia and elsewhere. A cursory study revealed that one of the main components of the scales was gypsum or calcium sulfate dihydrate. This paper discusses a typical undergraduate laboratory project to investigate the formation of calcium sulfate dihydrate scale on the surfaces of different types of pipes under isothermal conditions. This laboratory exercise is essentially a crystallization process and is suggested as one of the topics for final-year chemical engineering undergraduate project since it is a very important unit operation in the chemical, mineral, or pharmaceutical industries. Keywords: Calcium sulfate dihydrate, laboratory project, scale formation, and undergraduate curriculum..

Undergraduate Laboratory

A laboratory exercise is described that introduces the engineering student to design to meet a customer specification. The student learns to appreciate the system-engineering nature of design, where multiple objectives need to be satisfied. The design vehicle is one of the most conceptually simple instruments, namely a voltmeter based on a moving-coil movement. The student finds out how to reduce cost by making maximum use of the tolerance-forming part of the customer specification. He or she learns how both deterministic and statistical methods may be brought to bear. The statistical method applied may also be of more general interest to instrument designers working in industry.

Cutaneous Respiration

Gas exchange in animals is ultimately diffusion based, generally occurring across dedicated respiratory organs. In many aquatic amphibians, however, multiple modes of gas exchange exist, allowing for the partitioning of O2 uptake and CO2 excretion between respiratory organs with different efficiencies. For example, due to the physical properties of O2 being vastly different between air and water phases, the lung and skin play disproportionately important roles in O2 uptake. Many aquatic frogs are renowned for their cutaneous gas exchange capacity, where often the majority of CO2 is excreted across the skin. Furthermore, the roles of these gas exchange organs change with the animal's behavior. Under diving conditions, most of the frog's gas exchange needs must be met by the skin. In this article, we describe an interactive undergraduate laboratory that allows a class of students to share equipment while assessing pulmonary and cutaneous respiration in frogs provided with an air/water choice and under enforced dive conditions. Concepts explored in this laboratory exercise include animal energetics, diving reflex, pulmonary and cutaneous gas exchange processes, diffusion-based gas flux, and O2 debt.

Linear Induction Motors

The paper describes the results of an exercise on linear induction motors to demonstrate their principles in an undergraduate laboratory experiment. Basic linear motor characteristics are demonstrated and magnetic field strength measurements made. An equivalent circuit for the motor is derived from practical tests and results processed by a computer to predict motor efficiency and rotor thrust for various values of slip.
