Abstract
The fight against the popular belief about the widespread presence of underground rivers and lakes is addressed by formal education through the early introduction of the aquifer concept. Knowledge of the hydraulic parameters (porosity, permeability, etc.) is necessary for the correct understanding of the behavior of geological materials as such water reservoirs. At this stage, in addition to adequate basic information, an experimental visualization of what these parameters represent is necessary to achieve a full understanding of the subject. Generally, when experiments are carried out at school, measurements are made with different devices and materials and in a non-integrated way, what works against the construction of an integrated conceptual model by the student. A simple activity (and inexpensive in terms of the necessary equipment) is proposed so that students can perceive how the hydraulic parameters are linked to each other and observe the hydraulic behavior of different geological materials.
