and experiments in fluidmechanics, they generally do not possess the capabilities to perform hydrodynamic testing. Thispaper will present the work by the authors to develop a water flume that would allowhydrodynamic testing at velocities up to 2.0 m/s. The flume was constructed by anundergraduate and at a cost lower than commonly available commercial units. Both thefabrication process and the potential experiments that the flume could house are designed toimprove student learning in the area of fluid mechanics. The design is developed to be relativelycompact, with a 7’x3.5’ footprint and utilizes a commonly available single-stage centrifugalpump. Flow velocities in the test section can be varied passively by changing the insertcontaining the

or other dataacquisition tools and analyzed.The technical objectives are achieved as follows:Experimentally, determine stress in a part by measuring strain (understand relationship betweenstress and strain in linear elastic materials): A laboratory handout was developed to allowstudents to calculate the bending stress in the beams based on an applied load (most of thestudents have not yet completed strength of materials course). Students put various loads on the 3beam (50g, 100g, 200g, 500g) and record the corresponding strain values. They calculate stressbased on beam bending theory (s=Mc/I) and compare that with the experimentally determinedvalue from the strain measurements (s=Ee).Be able to

because it provided training inobservation, supplied detailed information, and aroused pupils’ interest.” [4] According to Blosser,however, the value of teaching labs was questioned in the 1970’s and 1980’s by several studiesthat examined student achievement, attitudes, critical thinking, cognitive style, scienceunderstanding, skill development, interest level, retention in courses, and the ability to workindependently. Some studies found no significant differences between groups who had labexperiences verses groups that did not. [5] However, in the intervening period of the early 21stCentury, numerous reviews and studies (more than can be cited practically here) refuted the late20th Century view and confirmed that laboratories are an important

car and hallway used for testing are shown in Figure 4. During the test, thecar is placed in various lateral starting positions and orientations on one end of the hallway. Thehallway used for testing is 7.5 feet wide by 43 feet long. When the car started with a clear viewof both sides of the hallway, it was able to stay close to the center of the hallway most of thetime. However, sometimes the car would travel in an S or zig-zag pattern, by overcorrecting inone direction and then overcorrecting again in the opposite direction about the center of lane.The zig-zagging resulted in lateral deviations of up to 1 foot on either side of the center of lane,and crossing the center of lane up to 13 times while traveling down the hallway.

Students voluntarily completed an end-of-semester survey on their achievementof the intended goals. Forty-seven students completed the course (eight were not declaredchemical engineers or freshmen); an additional five dropped the course within the first fewweeks of class. Thirty working solar-panel boxes were completed for twenty-three individual orteam projects (all students completed initial machine shop training), and thirty-seven surveyswere completed (79% response rate).

tocommunicate with the Arduino is extremely easy to install because it is an Add On inMATLAB®. The code to set up the input and output channels is simpler to understand sostudents would hopefully not be frustrated by a bunch of pre-written code that seemedmysterious. The wiring would be simpler since students would not have to use a screwdriver tosecure wires into a terminal. The Arduino is significantly cheaper than the myDAQ so it wouldbe possible to purchase additional units, allowing students to work in groups of two rather thanthree.Bibliography1. M. J.

Suchexperiments are typically found in curricula at both 4-year universities and 2-year colleges andare sometimes performed as part of an experimental sequence in physics courses as well. Inmany cases, they are part of a first or second course in electrical and computer engineering andall too frequently are presented in a somewhat superficial manner. Furthermore, the transformeris often assembled in an ad hoc fashion, and students are advised to be aware of safety

These blocks allow the instructor and any students who havecompleted the task to easily identify students who may need assistance.To accommodate this type of instructional arrangement, classes meet for longer periods of time(equal to the combined total of lecture plus lab hours allotted per week when those are taught asseparate classes in different rooms on different days and usually taught by different people).These longer class periods are assembled to align with university
