There are 8 partners schools involved in the project ,, Nature detectives '': Publiczne Gimnazjum im.płk. K.

Our schools are located in different sites, starting from villages and finishing in big cities, they are of a different size and number of pupils but in general the project involves 300 students aged 9-16 and 50 teachers. The main goal of the project is to increase our pupils' interest in nature balance and its lack influence on our life; nature is considered as local and global ,, treasure'', herritage . We focus on investigating ''alien'' expansive plants and animals, which are not natural in local/regional habitat, looking for impact of those species on environment , marking places of their appearance and informing local community about the influence of growing/having such ,,aliens''on local environment . The idea of the project appeared to investigate whether a friendly in one country animal or plant species can be friendly or harmful in another ( like snails from Portugal :-)). The project includes science, geography, allows to develop language skills, do a lot of outdoor activities, develop artistic and ICT skills. The first part of the project is going to focus on doing research in all partner schools environment what specific animals, plants could be the subject of our investigations (limited number). We also intend to learn about biodiversity of our places located in such different corners, even edges of Europe and about good practice solutions in ecology field if possible. It is an opportunity for those who are creative as the results of our work will have to be published, presented and documented in many different ways: photographs, drawings,PPt presentations, graphs, school and local magazine issues, school webpages, project blog, documentaries. It will also be a challenge and a great chance for students with some specific problems ( learning difficulties, social and economical problems) for developing language skills and improving ICT skills.
