A man is in the center of an ecosystem, everything that rounds him is potentially usefull. Man uses plants as a natural resource for survival as well as for learning ofscientific concepts, among others. ln the current work antocianidines present in summerflowers (Bouganviliea Glabra) and egg plant peels (Solanum Melongena) were used aspH indicators for strong acid-strong base neutralization reactions, replacing bromotimol.As an alternative for the work, students were involved in an active and participatingprocess for solving problems through research based on F Coit Butler’s model, DavidAusubel’s fundamental principle on educational psychology and research activities.The methodology used includes performing a pre-test to determine the students’knowledge level, followed by four learning activities that Iead to the solution, throughresearch, of a real life problem, the concept normality concept, the plants activeprinciples isolation such as the antocianidines, ant the neutralization concept.
