Water catchment, also known as rainwater harvesting, is the process of collecting and storing rainwater for future use. This can be done using various methods and systems to capture rainwater from rooftops, landsurfaces, or rock catchments before it enters the groundwater. It is an important conservation and sustainability practice that can help reduce reliance on municipal water sources and alleviate pressure on natural water supplies.
There are several methods of water catchment, including:
Rooftop Catchment: This involves capturing rainwater from the roofs of buildings and storing it in tanks or cisterns for later use.
Surface Catchment: This method collects rainwater from landsurfaces such as paved areas or open fields and directs it to storage containers or reservoirs.
Rock Catchment: In this method, rainwater is collected from rocksurfaces or natural depressions and channeled into storage systems for use.
Compare and contrast the advantages and disadvantages of water catchment as a sustainable water management practice.
Identify and explain the steps involved in setting up a basic water catchment system for a residential or commercial property.
Understanding the principles and methods of water catchment is essential for promoting responsible water usage and environmental stewardship. By implementing water catchment practices, individuals and communities can contribute to sustainable water management and conservation efforts.
The Living Environment: Students understand that cells are the basic unit of life, that all life as we know it has evolved through genetic transfer and natural selection to create a great diversity of organisms, and that these organisms create interdependent webs through which matter and energy flow. Students understand similarities and differences between humans and other organisms and the interconnections of these interdependent webs.
Cells: Students describe how living things are made up of one or more cells and the ways cells help organisms meet their basic needs.
Give examples of organisms that consist of a single cell and organisms that are made of a collection of cells.
