1. UMA PROPOSTA PARA O ENSINO DE LABORATÓRIO DE QUÍMICA ANALÍTICA QUALITATIVA
Teaching laboratory of qualitative analytical chemistry is still a controversial issue in chemistry courses. However, important researchers and educators in chemistry recognized and highlighted the importance that the contents of this discipline represent in the formation of chemists, once it can provide handling and understanding of microscopic phenomena ba

2. APLICAÇÃO DE CONDIMENTOS NA REVELAÇÃO DE IMPRESSÕES DIGITAIS LATENTES: UM EXPERIMENTO NO ENSINO DE QUÍMICA
The development of fingermarks is an important step in criminal cases. Latent fingermarks require applications of reagents to be developed before they can be visualized. Different techniques to enhance fingermarks’ visualization have been employed and the powder dusting is the most common among them. The use of food spices as latent fingermarks developers

3. ENZYMATIC RESOLUTION OF ANTIDEPRESSANT DRUG PRECURSORS IN AN UNDERGRADUATE LABORATORY
The use of biocatalysts in synthetic chemistry is a conventional methodology for preparing enantiomerically enriched compounds. Despite this fact, the number of experiments in chemical teaching laboratories that demonstrate the potential of enzymes in synthetic organic chemistry is limited. We describe a laboratory experiment in which students synthesized a

4. Un método para enseñar el porqué suceden las reacciones químicas
A methodology is proposed for explaining one of the central questions in the teaching of general chemistry courses to freshman students: why do chemical transformations occur? The answer to this question is based on thermodynamics but we propose arriving at an answer in a more intuitive way by using computational tools in a bid to increase the motivation of

5. Físico-química experimental: uma proposta para abordar equilíbrio de fases em sistemas ternários
On undergraduate courses, practical classes represent periods in which students can verify the concepts presented in theoretical classes. Conversely, the teaching internship in graduate programs allows these students to incorporate pedagogical practices into their experience, predominantly involving observation and reproduction of methods adopted by supervis

9. O trabalho experimental no ensino de Química
This article deals with conceptions of the experimental work in the Chemistry teaching, developed among teachers and students. The research was carried out using qualitative methodology, based on Gaston Bachelard's thoughts. The results showed dispersion of conceptions among both students and teachers. This dispersion, interpreted as a profile of conceptions
