This paper presents educational material that has been developed and will be utilised in an Environmental Education program entitled “Young researchers in a countryside path”. It pertains to primary school pupils of 5th and 6th grade, who, as young researchers, follow a countryside path, use the Global Positioning System (GPS) and perform specific activities, collect data and record their observations on worksheets. On their return to the PC lab, they put the data collected in the field into a Geographic Information System (GIS) in order to visualize their findings and create their own thematic map. Through these activities and the use of new technologies, students acquire knowledge, develop skills and abilities, and become aware of environmental issues always in accordance to the goals and objectives of Greek Cross Thematic Curriculum Framework for Compulsory Education and subjects syllabi. By observing, recording, managing and analyzing their spatial and environmental data, and forming cases that are verified in the dynamic nature of space and time, students go on to make suggestions and drawing conclusions from their work.
