2.3 Water systems
2.3 WATER SYSTEMS
Introduction
Our Earth looks blue from space because there is so much water in the form of oceans, seas and rivers, but also groundwater and clouds. People and most animals are also largely made up of water. Make pupils aware of the problems surrounding the availability of sufficient (drinking) water on earth, teach them about the water cycle and how we can all use water sustainably, and do so ourselves.
Relevance
Why?
The global water cycle is the bloodstream of ecosystems that allows nutrients to reach all its members, so we need to understand the fundamentals of how the water cycle works to know how to use water sustainably so that it is distributed to all members of the ecosystems.
How?
By learning about the limitations of water sources, we learn to find site-specific solutions to meet our water needs.
What?
Get to know your water needs and how to meet them without harming the others.
