About the Project
What Is the HydroHeroes Initiative?
Through interdisciplinary STEM activities, students investigate local and global water ecosystems, test water quality, and develop solutions to real environmental hydrochallenges.
Participating schools share their findings through a shared digital workspace, exchange cultural perspectives on water use, and co-create resources that can be used by classrooms across Europe. The project is built on the belief that young people, when given the right tools and international connections, can make a meaningful impact on the world around them.

Learning Approach
How Students become HydroHeroes
LOCAL WATER ATLASES
Collaborative Global Research and map
Through the eTwinning platform, partner schools share global data on water issues, floodings, water shortage and compare results across regions Students learn to communicate scientific findings in English, building both language and research skills simultaneously.
STEM in Action
Core Scientific Themes Explored through experimentation
HydroHeroes integrates multiple STEM disciplines into a cohesive, inquiry-driven learning experience. Each theme connects directly to European curriculum standards while offering authentic, project-based engagement. Experiments follow!
Smart Irrigation
The smart irrigation system is designed by students that ensures sustainable watering in the school garden. The system combines simple materials with automated control to deliver water directly to the plants, reducing waste and supporting healthy growth.
The Water Filter
Student -made filtration systems improve water quality. Through hands-on experimentation the students construct and test their water filters using everyday materials, such as, gravel, cotton, activated charcoal and sand. they observe changes in color and clarity and they and they compare filter designs to see which construction works best.
Rotational Stem Stations
Water Scarcity solutions Lab
Pollution barrier blocking challenge
Schools create teams which rotate
throughout activities to construct and test water filtering methods and pollution barriers that block rubbish from entering
the sea.
AR for blue sustainability - mixed country teams
Webar studio is used for presenting a zero emission ship, a robot that cleans the ocean, a research base for marine science and a regenerative aquafarm.
Partnership & Collaboration
A Network of European Schools
Schools water Footprint report
Students record the water systems used at school. Partners create their presentations based on photos taken from their water systems at school and the following table that students complete, projecting their drinking water infrastructure, the ecological usage of water, automatic watering, hydroponics, and other means used at school for managing water.

The Budget-Friendly Methods (DIY)
These are ideal for individual student projects or classrooms with limited funding.
The Wick System (Easiest): How it works: A cotton wick connects the plant roots to a reservoir of water. Capillary action "pulls" the water up.
School Use: Students can build these using recycled 2-liter soda bottles (cut in half, top inverted into the bottom).
The Kratky Method (Passive):
How it works: Plants sit in net cups above a jar of water. As the water level drops, the plant develops "air roots" to breathe.
School Use: Perfect for "set and forget" classroom windowsills. It requires no electricity or pumps, making it silent and safe.
Deep Water Culture (DWC):
How it works: Plants float on a foam raft in a tub of water. An aquarium air pump and air stone keep the water oxygenated.
School Use: Highly visual. Students can lift the raft to see the massive white root systems. It’s the standard for teaching the importance of oxygen in root health.
Active Water Sustainability

Map of HYDROHEROES ACTIVE ROLE IN WATER SUSTAINABILITY!
Hydroheroes this is your time to embark on a campaign supporting the protection of water sustainability. Did you visit a beach or a river in oder to clean it? Did you create a water podcast? Maybe you have taken interviews of water experts, or fishermen, maybe you implemeted an experiment related to measuring water quality on a beach or a river? You are invited to share your Active Water Sustainability Actions and make your voices heard!
Students are invited to share their Active Water Sustainability Actions ON OUR COLLABORATIVE MAP, add links, videos and make their voices heard!
Blue Sustainability Pledges
Students exchange water sustainability pledges. The aim is to foster environmental responsibility and intercultural dialogue by exchanging personalized water sustainability pledges between partner schools.
