”The SILENT SCREAM of WATER” is an international student communication and collaborative eTwinning project. In our project, teachers and students of 7 different countries, including Portugal, Romania, Bosnia and Herzegovina, Latvia, Spain, Poland and Turkey, conducted joint work on the theme of water literacy and water footprint. Our project consists of 137 students who study in high school and have an age range of 16-19 under the guidance of 19 teachers.

Importance Of water For Life

Water is the main source of life of living things. And nothing else can replace it. So it is the most important element after oxygen for human life. Water is an indispensable vital life support for all living things. It is found in the form of solid, liquid, gas in nature and exists in the life of living things with different sources.  In addition to its chemical and biological properties, water is an extremely effective value in the formation of civilizations, the formation of geographical and political boundaries.

Water Ratio in The World

Water covers three-quarters of the Earth’s surface. The total amount of water in the world is 1.4 million km3, and 97.5% of this water is salt water in the oceans. And of the remaining 2.5%, only 0.5% is available, while more than 90% of fresh water is at the poles and underground. We consume about 10% of the water in the world at homes, 70% in agriculture and 20% in industry.

On earth, especially drinkable water sources are rapidly polluting. Irregular urbanization, overpopulation, rising greenhouse gases and excessive industrialization are making the world increasingly “thirsty.” Some estimates suggest that over 3 billion people will face water shortages by 2025. What is happening is not a decrease in water, but an increase in the need for water. Due to the increasing population, climate change and rapid increase in consumption in economic processes, the future of water is negatively affected. Global warming and climate change are dragging the world into an uncertain future, threatening even water-rich countries.

Importance Of The Project:

Therefore, we must take care of the future of water and create urgent action plans. For this, we must support the training of individuals for careful use of water. Conscious use of water is only possible with knowledge of concepts such as water footprint and water literacy. We created this project to raise awareness about conscious water use for high school students. We aim for our students to learn the importance of water for living things. Also they will learn how it is polluted and how it should be protected. With water awareness, our students will also contribute to the conservation of the ecological system.

About The Event

Activities of our project in April were organized with the participation of students of the international mixed country team within the scope of “the 2021 STEM Discovery Campaign”. In the “Water and Life” study organized for this purpose, 5 different mixed country team students conducted studies together. Activities also defined special tasks related to the importance of water for living life and water sustainability. Team students performed tasks assigned by communication and cooperation.

“The SILENT SCREAM of WATER” Project 2. Team students ‘ studies on the importance of water in agriculture. Life is threatened by drought and it increases the salt content in the soil. Therefore 2.team students worked together to identify the effects of drought and salinity increases that threaten the soil on agriculture and to develop alternative solutions. This work will run from 1 to 30 April 2021 in the international 2. mixed country team conducted in collaboration with students

A Seed Story

Everything starts with a seed and the seed meets the soil. Then it takes the first life of water . It grows and becomes a seedling, then turns into a huge tree after many years. As the cycle continues in a way of health, soil, water and climate become friends with one another. A decrease in water resources causes drought in the soil but dry soil can not feed plants. A plant that cannot get enough water and minerals from the soil cannot continue to live . If the water runs out, the Earth dries up and then life ends. Project students drew pictures to tell the seed’s journey and they also created e-books by writing the story of a seed.


Alternative Farming Methods For Drought

We use 70% of fresh water in the world in the agricultural sector. 53% of this water is supplied from surface water sources and 38% from ground water. 82% of the irrigated agricultural areas are irrigated by Keel irrigation, 17% by sprinkler irrigation and 1% by drip irrigation. Numerical data show that irrigation used in agriculture threatens clean water skis. The establishment of economical irrigation systems in agriculture is of great importance. Project students explored alternative irrigation methods used around the world such as; rain irrigation, drip irrigation, desalination in water, collecting water in the air by conducting research on the irrigation techniques used to prepare an e-journal with sample applications.


A New Idea For Alternative Irrigation In Agriculture.

Project students developed solutions for creative irrigation methods using the knowledge obtained after their research. For this the students made agricultural field sketches using STEM knowledge to get products using less water in agriculture.

We generate energy by solar panels to convert solar energy into energy and we generate the stored energy by transferring it to the battery. When the humidity in the soil falls below the normal level, the battery activates and activates the cooling system. At this time, the moisture collector sheets begin to cool. Moisture in between hits this plate and turns into water. Water droplets accumulated in the plate and they are collected in the water container at the bottom. We send the water in this container to the drip system by the pump. In this way, we use energy with a closed-circuit energy system and turn the moisture in the air into water and water our field.

Intelligent Greenhouse Automation

At this stage, our students moved to the design department. They designed intelligent greenhouse automation with arduino for quality agriculture and irrigation. With the circuit they installed, they designed a greenhouse that accumulates rainwater or uses the water requirement by storing the humidity in the air. Smart greenhouse makes controlled irrigation according to the moisture value in the soil. It works to grow quality products by lighting Day and night with the right lighting technique. Students created circuit diagrams of the greenhouse they designed with Fritzing. Then they did the coding for the design with the Arduino program and the coding of greenhouse automation. They prepare a prototype prepared for the application. And our project is working.

Astro-Stem is an eTwinning project. Between September 2019 and May 2020, an international project that briought together astronomy and STEM disciplines were realized.

About The Project

The project is compatible with the educational curricula of 5 different countries: Turkey, Poland, Serbia, Bosnia and Herzegovina and Macedonia. The project was carried out with interdisciplinary interaction of teachers of Mathematics, Chemistry, Physics, Biology, Computer and Technology. See the map showing all schools involved.

Under the guidance of 24 teachers,187 students in the 15-18 age range participated actively in the project. The project designed astronomy activities with STEM aimed to raise awareness about space sciences in students. Thus, the project inspired them to become interested in the science of astronomy while planning future professional careers.

Mixed country teams were formed and students carried out their activities through collaborative activities. Thus, the communication of students living in different countries of the same age group was provided and foreign language development was supported. In addition, cultural ties between countries have been established and a democratic learning environment has been established.

The project included studies on astronomy, space, telescopes, constellations, black holes, other planets, our galaxy, the moon and solar eclipses, as well as information and crops. Each study started with STEM questions and continued with students’ research and applications. By using a different web tool at each event, students’ technology literacy skills were improved. In this project, Scientix Resources Building a Space Habitat in the Classroom and “The Solar System” were used.

The activities took place with two different working groups, school teams and mixed country teams.
