In particular, the experiment confronts themisconception that in a stationary fluid the pressure at a given depth is determined by the weightof the water above that depth. The measurements and the apparatus are very simple. It is possiblefor students to complete the exercise with only a basic knowledge of physics and without anyprior exposure to fluid mechanics. Figure 1 shows the apparatus for the tank-filling experiment. Two cylindrical tanks made ofacrylic are placed side-by-side on the workbench. One tank has a uniform diameter and the otherhas a step change in diameter. Both tanks have a pressure transducer (Omega PX181B-001G5V)on the side at a distance H from the base.

certainly not without itschallenges. While it is a common practice at many Universities to require engineeringstudents to take courses in the liberal arts, the opposite is often not the situation. AtUSMA, however, all graduates receive a Bachelor of Science degree regardless of theiracademic major. With this in mind, students who choose to major in the liberal arts arerequired to take, at a minimum, a three-course engineering ‘core’ sequence from one ofthe Academy’s eight engineering programs in order to graduate. Table 1 shows the three-course core sequence for the Mechanical Engineering Department: Table 1. Mechanical Engineering Three-Course Core Sequence Course Content

Withproject-based learning students shift from a passive to an active learning pattern that is likely toimprove knowledge retention as well as the ability to integrate material from different courses[1]Like many undergraduate engineering schools in the nation, our university emphasizes a hands-on approach in engineering education. From the beginning of the freshman year to the senioryear, students participate in different levels of engineering projects, from LEGO Mindstormsdesigns, to conducting a research project.

and safety concerns of using Class 4 lasers prevent this technology being used in the undergraduate and graduate laboratory teaching. Recently, however, a relatively inexpensive, and safe for classroom use ‘educational Particle Image Velocimetry’ (ePIV) system with web based interactive software was developed. This novel technology is an instrument that can be used in diverse educational settings because of its effectiveness as an education tool, high-tech appeal, compact size, low cost and safety. In this paper we introduce ePIV, describe its components in detail and provide examples of how it can be used to enhance undergraduate and graduate laboratory experience.1.

A project—design of a controller for a coupled-tankapparatus—was used as the hands-on experience for making connections between the theorydiscussed in the lectures and the implementation of the control concepts, such as transferfunctions, performance, and stability of feedback control systems, in the laboratory. During thefive-week project, students were required to: 1) characterize level sensors and variable speedpumps; 2) mathematically model the coupled tanks; 3) design a closed-loop transfer function; 4)design the controller for the system; and 5) implement the controller using LabVIEW.

well as to analyze and interpret data.”ABET EC2000 presented a paradigm shift in dealing with engineering laboratories. Studentshave to design their own experiments instead of only conducting recipe-type experiments anddealing with collected data. In doing this, the students can achieve several outcomes and beprepared for the profession.For an engineering program seeking ABET accreditation, several questions related toundergraduate laboratories need to be answered: 1. Why is it important for professional engineers to be able to design and conduct experiments? To which extent can the undergraduate lab experience simulate the professional engineering practice? 2. What are the fundamental objectives that could be met through the
