Resumen

A man is in the center of an ecosystem, everything that rounds him is potentially use
full. Man uses plants as a natural resource for survival as well as for learning of
scientific concepts, among others. ln the current work antocianidines present in summer
flowers (Bouganviliea Glabra) and egg plant peels (Solanum Melongena) were used as
pH indicators for strong acid-strong base neutralization reactions, replacing bromotimol.
As an alternative for the work, students were involved in an active and participating
process for solving problems through research based on F Coit Butler’s model, David
Ausubel’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, through
research, of a real life problem, the concept normality concept, the plants active
principles isolation such as the antocianidines, ant the neutralization concept.
