This work took place in two public schools located in the city of Giruá, RS. Teachers and students from both the elementary school and high school participated actively in the process of studying the Santo Cristo River. Groups of teachers and teachers' assistants were selected to help devising a series of activities such as: theoretical classes on watersheds, applying protocols on characterizing watersheds, gathering and analyzing the quality of water from the river, writing educational guides, and presenting the ongoing work in local and regional seminars. The students also answered a questionnaire to check their knowledge before and after the activities developed. Students' participation revealed the importance of this learning process and knowledge systematization in the corresponding presentations to the community. Hence, it is really important to consolidate groups of teachers and teachers' assistants to improving knowledge generation of local environment and community participation in the environmental issues.
