One can use textbook exercises as a springboard for this process. A textbook exercise can be solved analytically first, then, it can be implemented in the laboratory for the purposes of testing and verification of analytical results. In this project, for example, the siphon was a textbook exercise that was solved analytically; first by assuming an ideal operation that neglected losses; then, by using a more realistic analysis that included the effects of losses. Implementation through an experiment allowed students to design, build and test a model of the textbook exercise by themselves and, subsequently, compare the experimental results to those obtained analytically. The end result was that students were able to assess the extent to which the results of their analyses were realistic [3].
