Bruna M. Damm; Izabela de F. Schaffel; Gabriel F. S. dos Santos; Lilia E. S. Azevedo; Rafael de Q. Ferreira; Paulo R. G. de Moura – Journal of Chemical Education, 2023
Antioxidants are molecules that act against free radicals, and this effect can bring many benefits to health and society. Antioxidants can be found in various matrices of nature, such as fruits and plants. Some studies have shown that "Rhizophora mangle," a typical mangrove plant, is rich in antioxidants. People report its use for…

Mikeas Silva de Lima; Lilian Pozzer; Salete Linhares Queiroz – Journal of Chemical Education, 2023
The mining industry in Brazil, despite contributing to economic growth, is one of the human activities that negatively impacts the environment. This situation can be contextualized in discussions of several curricular chemistry topics. One way in which science, technology, society, and environmental issues can be discussed in classes is through…

da Silva Costa, Mauricio Bruno; dos Santos, Bruno Ferreira – Chemistry Education Research and Practice, 2022
The learning of scientific concepts is one of the main research subjects in science education. Although little used, the theory of conceptual profiles allows the study of this knowledge, taking into account the presence of different ways of thinking about a certain concept in the same individual. This study aimed to build a conceptual profile for…

Schmitz, Gabriela L.; Nogara, Pablo A.; Medina, Natiéle; da Rocha, João Batista T.; Vargas Barbosa, Nilda; Segatto, Ana Lúcia A.; Oliveira, Cláudia S. – Journal of Biological Education, 2022
Enzymes are organic molecules known for their catalytic nature because they accelerate metabolic reactions in organisms. The study of enzyme functions and modes of action is essential to understand Biochemistry. This study aimed to analyse the acetylcholinesterase enzymatic activity, as well as the enzymatic inhibition mechanism in practical…

Gomes, Victor V.; Cavaco, Sofia C. F.; Morgado, Carmen P.; Aires-de-Sousa, João; Fernandes, Julio C. B. – Journal of Chemical Education, 2020
This work describes a simple talking calorimeter for the visually impaired based on the Arduino Uno without any shield. An electronic interface was designed using a Wheatstone bridge, a thermistor, or an operational amplifier (opamp). The temperature values are communicated by a loudspeaker connected to pulse-width modulation (PWM) digital output…

Anjos, R. M.; Amaral, S. S. G.; Muniz, M. C.; Cardoso, R. P.; Bernardo, T. A. S.; Guerrieri, A.; Lage, L. L. – Physics Education, 2020
Harmful plastic debris found on beaches and in the oceans are not limited to drinking straws or bags. There are several synthetic organic polymers that can be used to make different kinds of plastic materials and have resulted in billions of tons of waste that can reach the aquatic biome and are harmful to freshwater and marine communities as well…
