Laboratory Experience: Comparison of Bovine Catalase Activity of Liver and Heart with the Support of Cell Phone Videos

Secondary school teachers need to acquire new tools to capture the attention of students and to be able to transmit the knowledge necessary to cover the contents of the curriculum. One of the methodologies we propose is the use of simple laboratory practices that allow teachers to demonstrate and incorporate knowledge through experimentation, trial and error. Therefore, the purpose of our work is to develop a simple laboratory experience for secondary school students. We also consider it relevant to incorporate technologies that motivate students in the study of subjects related to Biological Sciences, Physics, and Chemistry.
