We present in this paper a class work for solving investigative problems, inserted into the theoretical constructivist context. We have chosen the topic «Dye wool with natural dyers», for its relevance in Organic Chemistry and also for its cultural and social interest, showing an actual perspective of Science.On the other hand, we develop the class performance with emphasis in assessment.
