This article describes and analyses the results obtained in a didactical experimental strategy, structured in the Teaching and Learning model which is based on research. The students are involved in situations, where problems related with the soil are used in order to help the significative construction of the acid and base's concepts related to the Lewis' Theory in order to increase the students mental ability for analysing and synthesizing and also to develop their attitudes towards science.

The study of Lewis' acid-base theory from the reactions of phenolic substances in medicinal plants.This study is a proposal for a simple execution experiment, which uses easy to acquire, low cost materials, with the theme of medicinal plants, enabling approaches to Chemistry, Physics and Biology concepts.By infusion, six phenolic substances were extracted from six medicinal plants, which were made to react with a 1% (w/v) aqueous solution of ferric chloride to form salts of different colors, according ...
