• Resumen

  • Instrumentation available for teachers and students has changed considerably during the last 20 years. The data logger-sensor system has the advantage of taking reliable measurements over time with suitable sample rates. This experiment is not an open-ended investigation but an opportunity to explore the established relationship between the pressure exerted by a fluid above a point in a cylinder of water and the height of water above that point. Both motion and pressure sensors1 are employed, leading to a measurement of the acceleration due to gravity. Earlier electronic data sampling techniques have been used to investigate fluid properties in a variety of experiments.2
