International School students from Years 1–9 exchanged their usual classroom environment for a day surrounded by nature during a visit to Radmilovac, organised as part of the school’s Classroom Without Walls programme.

The visit took students to the Mali Dunav Centre for Fisheries and Applied Hydrobiology, located within the Radmilovac experimental estate of the University of Belgrade Faculty of Agriculture. Designed as a place where visitors can discover the life of the Danube and its surroundings, the centre combines education, science and nature in an engaging outdoor environment.

Discovering the Life of the Danube
During their time at Radmilovac, students had the opportunity to explore an environment inspired by the Danube ecosystem and learn more about the rich plant and animal life connected with water. The centre’s “Mali Dunav” is a model river stretching for more than 1,000 metres and includes a variety of educational areas dedicated to aquatic life and the importance of water.
Among the centre’s attractions are an aquarium featuring fish species from the Danube, a small aquatic botanical garden, areas with water birds and turtles, as well as spaces dedicated to fishing traditions and life by the river. Together, these features provide an engaging setting in which students can discover how different species live and interact within aquatic ecosystems.
Being able to encounter these topics outside the classroom offered students a different perspective on the natural world. Exploring the surroundings together encouraged observation, curiosity and discussion, while giving younger and older students alike the opportunity to connect scientific ideas with real-life examples.
Learning Through Nature and First-Hand Experience
The Classroom Without Walls programme is all about expanding learning beyond textbooks and school desks, and Radmilovac provided an ideal setting for doing just that. Surrounded by greenery, water and diverse wildlife, students were able to experience how learning can become more memorable when it is connected with direct observation and exploration.
The visit also encouraged students to think about the importance of ecosystems, biodiversity and the relationship between people and the natural environment. Experiences like these can help develop environmental awareness while inspiring students to ask questions and take a closer interest in the living world around them.
Spending the day together outside school also offered plenty of opportunities for students from Years 1–9 to share impressions, communicate and enjoy learning in a relaxed setting. The combination of education, exploration and time in nature made the visit a rewarding experience for all age groups.
The trip to Radmilovac was another enriching Classroom Without Walls experience, giving International School students the chance to discover the natural world from a new perspective and reminding them that some of the most interesting lessons can begin simply by stepping outside the classroom.
