The design of a bio-infiltration pond and associated monitoring systemalso requires the students to develop a set of experiments that can be applied consistently byfuture students to monitor the effectiveness of the pond (enhancing outcome b). Finally, thestudents must effectively communicate with local stormwater managers to ensure that theirdesign is meeting jurisdictional needs (enhancing outcome g). Overall, this senior design casestudy project satisfies the necessary ABET student outcomes, while allowing the students toachieve a few of the outcomes (b, c, g, i, and j) at a higher level when compared to

Once the hammer has made contact with the EM, the circuit isthen opened due to the discontinuity between the bell and metallic ring, and the EM is no longermagnetized enough to hold the attraction of the hammer, thus the hammer returns to its originalposition, re-closing the circuit and starting the whole process over again. a b c Figure 1: Electric bell.
