Demonstration kit Water supply
Investigating Water Supply Systems, Water Pressure and Storage
Grade level: Grade 3 and above
Use: Demonstrations on water supply systems, water transport using a centrifugal pump, pressure pipes, communicating vessels, elevated water tanks and the function of a water tower
With the Demonstration kit Water supply, students investigate how water can be transported, distributed and stored within a water supply system. The demonstration model illustrates fundamental principles of water supply and connects scientific concepts with technical applications.
A centrifugal pump transports the water through a pressurised pipe system. This demonstrates how water moves through pipes and illustrates the role of a pump in a water supply network.
The included elevated water tank allows students to investigate the principle of communicating vessels. At the same time, the model demonstrates how a water tower or elevated tank functions as a reservoir within a water supply system. A cutaway model of a water tap provides an additional view of an important technical component.
The kit also provides opportunities to address topics relating to drinking water and wastewater, encouraging students to consider water as an essential natural resource. A comprehensive teacher's guide with methodological guidance, experiment instructions and reproducible worksheets supports classroom use in primary education.
Technical specifications
Size of kit: 540 x 450 x 150 mm
Show that a significant quantity of water can be obtained from the taps even if the pump is turned off for a while.
Let the students examine the centrifugal pump first (construction and operation).
Show that a significant quantity of water can only be obtained from the taps while the pump is running.
