Guardians of the Streams engaged children from Kweebus, in partnership with Toverbos, in the exploration of local freshwater ecosystems near Beersel, Belgium. Over several months, the children visited rivers and streams such as the Zenne, Geleytsbeek and Linkebeek, across different seasons and weather conditions.
Through repeated field visits, they learned to observe and measure key indicators of water quality, including temperature, turbidity, pH and nitrates. They also explored biodiversity, identified visible pollution, and reflected on the impact of human activities on river ecosystems.
The project combined scientific inquiry with outdoor learning and environmental responsibility. Children collected data, compared results between sites, and developed hypotheses about water quality and ecological changes. Some outings also included litter collection and sorting, reinforcing the connection between observation and action.
By working directly in nature, children developed ecological awareness, scientific curiosity and a sense of responsibility toward their local environment. The project demonstrated that meaningful water education can be achieved through simple, regular engagement with nearby rivers. It encouraged children to become active, attentive and caring guardians of the streams around them.
The following scores were calculated using a statistically-driven machine-learning approach, a type of AI that learns to perform a task by analysing patterns in data. This is an experimental approach to citizen-science impact assessment, and the exact reasoning behind the scores is not explainable. The scores represent a best guess of the impact the project is having in each domain. Scores are recalculated and updated when “View impact report” is clicked.
Proportion of questions answered in each domain.
This is the beginning of a journey (some would say a "trajectory" ) along more than 200 questions. Don't worry; you don't have to answer them all at once. Do something, and come back some other day. You will find a lot of help along the way, and if you're generally happy to start, just click on "Ok, I got it!" below. If you're unsure how to answer a question, again, don't worry, answer it in the way that makes most sense to your project and you can always come back and change it later. If you still have doubts about life, the universe and everything, now or later, head to where to find help for advice and all the clarity you might look for.
