The main priority of the project was to support the subjects of natural sciences (mathematics, physics, chemistry, biology), ICT and technical education, and also to connect the concept of STEM to the development of creativity. Moreover, important elements of the project were linking up education to a real environment, and teamwork at school and international level. The vast majority of activities were focused on group and collective learning in different environments, so the number of pupils involved was high. The project was going on two levels, school and international. The school part of the project was based on regularity, everyday activities, pupil's own motivation and participation calls. The project consisted of a number of sub-activities that ran continuously throughout the school year and were presented on the project website. These activities included class projects focusing on natural sciences and ICT subjects, lectures, discussions, as well as exhibitions and excursions to museums and science centers. The second level was represented by cooperation with our partner schools. Each partner school chose one topic from STEM. The school together with the local community prepared a five-day conference programme on the topic. The programme included workshops, discussions, competitions, exhibitions, cultural events, museum visits, meetings with experts, etc. The project focused not only on cognitive educational goals, but also on affective and social ones. Pupils learned to use their abilities, skills and knowledge, to find creative solutions and to create a positive relationship and motivation to study natural sciences and technical subjects. Pupils also learned to present results of their work both in the school environment and at international events. Thanks to the project, pupils also developed their cooperative and communication skills and met pupils from other European countries and learned mutual respect.
