The paper gives the result of an experiment in which 24 high school students in the final year (age 18-19) calculated limits originated in reality and modelled the limiting process with an Excel application. The students answered a questionnaire to find out if they found the lesson interesting, understood the mathematics involved and if the models benefited the learning. The result is discussed.
