SILVEIRA, Felipe Alves; VASCONCELOS, Ana Karine Portela  and  NUNES, Albino Oliveira. A didactic sequence on the study of acids and bases from the perspective of Critical Meaningful Learning theory: An analysis of this epistemological approach. Ciência educ. [online]. 2025, vol.31, e25005.  Epub Mar 11, 2025. ISSN 1980-850X.  https://doi.org/10.1590/1516-731320250005.

Experimentation in chemistry plays a crucial role in promoting learning by allowing the application of concepts, relating them to the real world, and bridging theory and practice. Based on the Critical Meaningful Learning Theory, this work aims to propose a teaching sequence that includes experiments that focus on ideas related to inorganic compounds (acids, bases, and oxides). The proposed activity seeks to integrate theory and practice by using a text entitled Understanding acid rain: Does it kill? and a concept map designed for secondary school students. By connecting their prior knowledge with new information, students will actively participate in the learning process, thereby stimulating curiosity and reflection. This approach facilitates the assimilation and retention of knowledge while considering cultural and social contexts and promotes values such as social responsibility through critical meaningful learning.

Keywords : Chemistry teaching; Secondary school; Critical meaningful learning theory; Acid rain; Didactic sequence.
