World Water Day is celebrated on March 22 every year to draw the attention of people around the world to the importance of conserving drinking water. The theme of this year's celebration is "Groundwater", and the name of the campaign is "Groundwater - make it invisible".
Groundwater is invisible, but its impact is visible everywhere. They feed springs, rivers, and lakes and penetrate the seas and oceans.
Almost all liquid fresh water in the world is groundwater, and life without it is not possible. It is used for drinking water supply, sanitary systems, agriculture, industry and ecosystems. Unfortunately, human activities overuse and pollute groundwater.
What can we do? We need to protect groundwater from pollution and use it sustainably, balancing the needs of people and the world.
This year we marked World Water Day by researching water and its properties. By conducting experiments, fifth graders learned what buoyancy is and why they are "lighter" in seawater than in a swimming pool. The students discovered why fish move through the water more easily and quickly and what adaptations allow them to do so. They peeked into a drop of swamp water with a microscope and discovered various single-celled organisms. They examined the surface tension of water and how a man can destroy it by releasing detergent into the water, and how this has a detrimental effect on the living beings that live in it.
Through the research, students gained new knowledge about water - the fluid of life and its importance for all living things on Earth.
