The “Clean Water” project aims to increase children's awareness of the importance of clean water for health, the environment and life on Earth and to encourage them to take actions to protect water. These can be simple steps such as saving water at home, separating garbage or planting coastal plants. Through education, practical activities and a creative approach, children will learn how to care for water and protect it from pollution. They will discover the secrets of water, its life cycle and its impact on the environment. They will learn about the richness of the water ecosystem in their immediate surroundings: river, lake, sea. They will learn what organisms live in these environments and how they are related to them. The project will use the STEAM teaching model. Students will perform exercises to find a solution to the problem. During the project, sample activities are proposed: collecting information, art works, experiments, coding, the "Clean River" campaign, water quality testing, building a mini sewage treatment plant, information campaign to save water, stories about a drop of water - to be agreed upon jointly.
