Abstract:

Chemistry teaching provides for experiments that require laboratories and utensils that are not easily accessible, however, due to the pandemic, several experiments were rethought. In the current context, the execution of these experiments in other physical spaces (not the laboratories of educational institutions) as well as their execution by students in their homes, expand the possibilities of carrying out chemistry experiments in the context of hybrid education and/or distance education. In this perspective, the objective of this research was to identify chemistry experiments to do out of the laboratories. The methodology consisted of bibliographical research in the “Journal of Chemical Education”, in its publications/issues from the year 2020. A total of 15 articles were selected. The bibliographical research allowed identifying different proposals to bring chemistry laboratories to students' homes or to other physical spaces. In designing these experiments, the important considerations that were made included the elimination of potential safety issues in a home-based lab, ease of availability of reagents and labware, similarity to an experiment that would be done in a lab. Among the identified practices were: the use of individual kits that were created by the teacher and sent to students' homes to carry out experiments; the use of safe household items and no special equipment to carry out experiments; the creation of chemical models with materials acquired in supermarkets, pharmacies and stationery stores and these associated with activities mediated by Augmented Reality Application for teaching chemistry; and, remote laboratory with experiments delivered in real-time, using equipment controlled remotely via the internet. Among the topics addressed in the experiments were: intermolecular interactions, pH, acid–base titrations, solubility, phase equilibria, thermodynamics, precipitation reactions, endothermic and exothermic processes, study of the crystal structure of metals, analytical chemistry, quantitative analysis, instrumental analysis, biochemistry experiments. Experiments were identified aimed at high school students, as well as undergraduate students, whose approach was distinguished by the depth in terms of treatment and analysis of experimental data in activities applied to higher education. Most of these experiments were designed as an at-home experiment during the pandemic times, making them suitable for hybrid and distance education, as well as they could easily be adapted to use in typical school and/or undergraduate rooms. Details of these chemistry experiments will be presented in the final paper.
