Artesian Well: Functional Model

Artesian Well: Functional Model for Geography Lessons

Artesian well model demonstrating how to apply the laws of physics and connecting vessels to obtain water from underground aquifers. The model also demonstrates the operation of a subartesian well, whose resources are often used, for example, in farms and places where access to municipal water is difficult.

In addition to the artesian and subartesian well operation, the model includes two water supply zones, which, thanks to rainfall simulated by pouring water into the funnels, visually illustrate how aquifer layers function, based on the principles of the principle of communicating vessels. The set includes three interchangeable backdrops and colorants, which allow demonstration of pollutant penetration, which then enters groundwater. On the backdrops the arrangement of layers is shown.

The model-mock-up is an excellent way to visually present during lessons the differences and similarities in the functioning of artesian and subartesian wells, their definitions, as well as the cycle of contaminants, which enter water as a result of human activity.

Contents of the set:

• Model of the well with two supply zones and interchangeable backdrop for demonstrating the operation of artesian and subartesian wells
• Three interchangeable waterproof backdrops illustrating the diagrams of the aquifer layering, supply zones and the well, including one backdrop depicting environmental degradation due to pollution
• Plastic beaker (2 pcs) • Stirrer • Storage container for the model, serving as the base of the model and as a water reservoir
• Dyes: blue and red
• Instruction with teacher's notes
• Student assessment card
