Clay Pot Filtration - Irina's team from Cornu Luncii Secondary School, Romania


Our method of water filtration was CLAY POT FILTRATION.

We did this activity in many days. First, we researched about this method. We found out that it was one of the oldest methods of cleaning water, dating back over 4,000 years. It was used by ancient civilizations such as the Egyptians, Indians, and Chinese to improve water quality. Although simple, this method is still effective today and continues to be used in modern forms to provide safe drinking water, especially in rural area.

In our activity, we used different clay pots: one of light color and one of dark color. We used tap water and dirty water. We filled these pots with water and we waited until the next day. In both case, we could noticed some impurities on  the surface of the water.

One of my classmate did this experiment at home and the result was the same.

This method is easy to use, needs low cost, does not require electricity and it is suitable for household use.

Unfortunately, this method does not completely remote all viruses and chemical contaminants.

Storing water in a copper or silver vessel - Nesreen Teacher’s Team -Al-khairya Primary Mixed School- Jordan

 What is the Copper or Silver Vessel Method? The copper or silver vessel method is a traditional way to make water cleaner and safer. In this method, water is stored in a vessel made of copper or silver for several hours. These metals help reduce harmful germs in the water. This method has been used for many years in different cultures. What Does This Method Remove? Storing water in a copper or silver vessel helps reduce many microorganisms. These include bacteria and some viruses that can cause diseases. The metal surface slowly releases natural ions that stop germs from growing, making the water safer to drink. How Do We Use This Method? First, we clean the copper or silver vessel very well. Then we fill it with drinking water. We leave the water in the vessel for about 6 to 8 hours or overnight. After that, the water is ready to use or drink. Advantages of the Copper or Silver Vessel Method This method is simple and natural. It does not need electricity or chemicals. It is low-c...

EGG WHITE METHOD_ KEMALETTIN TUGCU SECONDARY SCHOOL- MERVE TACAR'S TEAM (TÜRKİYE-İSTANBUL)

BEFORE THE EXPERIMENT STUDENTS DID RESEARCH ABOUT THIS METHOD AND DECIDED TO CHOOSE WHAT KIND OF WATER THEY SHOULD USE DURING THE EXPERIMENT EGG WHITE USE TO CLEAN WATER There is no evidence that people originally developed the egg-white method specifically to clarify drinking water. The earliest clearly documented use of egg white for clarifying liquids appears in early modern Europe, during 16th–17th century , mainly for food and drink (broths, wines), not water.   Egg white is used because its proteins coagulate when it is heated. The coagulated proteins trap impurities. The goal is clarity and refinement , not sanitation There are scientific references showing that egg white (or egg-white proteins) can serve as a coagulant to remove suspended particles from water or wastewater systems ,but these studies focus on a modified egg white or use it in combination with polymers not raw egg white alone. Although we know egg white can not be used to to make drinkab...

Melahat Yıldırım's Team, İlyaslı S.S Uşak, Türkiye

Melahat Yıldırım 's team Water Wisdom eTwinning project Activity Title: Plant based clarification method  Activity Description: In this activity, students first researched the cedar tree and its role in water purification. After the research phase, we collected cedar branches and leaves from the school garden. These materials were placed in a bottle filled with water. The students observed the water over time and shared their observations. This activity helped students learn about natural water purification methods and environmental awareness.
