In the presented study, an experimental set-up for use in an undergraduate fluid mechanics laboratory was designed, built and constructed by a graduate student. Two basic educational objectives were determined for this study: to give a good education to the graduate student as both a graduate teaching assistant and as an engineer, and to create a laboratory experiment for undergraduates. Important aspects of experimental studies were introduced to the undergraduate students by using the built set-up, from understanding the basic theory to performing error calculations. The objectives that were fulfilled for the graduate student's education were evaluated using Bloom's taxonomy. The improvement in undergraduate knowledge on the subject was examined by comparing the scores that the undergraduates attained in oral exams that they took before they conducted the experiments with the scores that they achieved from the reports they prepared after they had conducted the experiments.
