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 compl...

CHARCOAL PURIFICATION - YUŞA BERGUT'S TEAM

Image
We researched about how this method works and then we carried out an experiment and tried to apply the method. Charcoal purification is a simple method used to clean a substance by using activated charcoal. Activated charcoal has many tiny pores on its surface, which allows it to trap unwanted impurities. It works by adsorbing substances such as color, odor, or harmful chemicals onto its surface. This method is commonly used in chemistry to remove impurities from solutions, as well as in water and air filtration systems to improve quality.  We hope you enjoy our video. 😊

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...

BOILING METHOD- GULSUM TEACHER'S TEAM- KEMALETTIN TUGCU SECONDARY SCHOOL-TÜRKİYE İSTANBUL

  , What is the Boiling Method? The boiling method is a way to clean water by heating it. When water is boiled, it becomes very hot. This heat helps to kill harmful germs in the water. Boiling is one of the oldest and easiest water cleaning methods. What Does the Boiling Method Remove? Boiling water kills many microorganisms. These include bacteria, viruses, and parasites. These germs can make people sick. After boiling, the water becomes safer to drink. How Do We Use the Boiling Method? First, we put the water into a clean pot. Then we heat the water until it starts to boil. We boil the water for about 5 to 10 minutes. After that, we let the water cool down and keep it in a clean container. Advantages of the Boiling Method The boiling method is easy to use. We do not need special tools. It is useful at home, in nature, or in emergencies. It is a good way to make water safer. Limits of the Boiling Method Boiling water does not remove dirt, chemicals, or heavy metals. Also,...

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.

Filtering Dirty Water with Pebbles🔬 Simple Water Filtration Experiment – Short Summary In this experiment, students made a simple water filter using clean pebbles and a cloth. Dirty water was poured through the filter to observe the changes. The pebbles trapped large pieces of dirt, and the water looked clearer after filtering. This experiment helped students understand how simple filtration works and how pebbles can remove visible dirt from water. Before students begin applying their chosen water purification methods, they tconducted thorough background research. They investigated questions such as: Where has this method been used? How old is the technique? Was it originally developed for drinking water purification or for general-use water? We had an amazing experiment experiences with my Team♥️ ✨Our School Principal supported us for our experiment process✨

Aerating The Water- YAVUZ SELİM SECONDARY SCHOOL - Emine Halıcı's Team

                 Water Wisdom    eTwinning Project                      Aerating The    Water     Methods   Activity 1- Cleaning  with water  aeration is a natural method used  especially  to increase  the drinking  water level. 2- First, we     did    research    how to purify   the water system. Our process : We   recorded the purification process of our experiment. Students    collected   rain   water   and examined   the rain water   drop under the misroscope. There was something alive in   the rain   water.  3 -Students  used  a clean glass bottle  for experiment. 4-   Students filled the bottle with rain water. 5- They mixed the water for 30 seconds to 1 minute. 6- After mixing, w...

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

Image
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...
