Article Abstrct: We describe  an easy  and  fun  project  using  water rockets to demonstrate applications of single variable calculus concepts. We provide procedures  and a supplies list for  launching and  videotaping a water rocket flight to provide the experimental data. Because of factors such as fuel expulsion and wind effects, the water rocket does not follow the parabolic  model  of  a textbook  projectile , so instead we develop a one-variable height vs. time polynomial model by in­terpolating observed data points. We then analyze this model using methods suitable to a first semester calculus course. We include a list of questions and partial  solutions for our project  in which  students use calculus techniques to find quantities not apparent from direct observation. We also include a list of websites and other resources to complement  and  extend this project.

While this piece specifically does NOT use differential equations it is about how one could collect data to use in a differential equation model for projectile motion. Moreover, there are several excellent references.
