This article derives from a broader investigation carried out as part of the doctoral research “Digital relations between families and school. Technologies and social participation for learning in High School” which took place at Colegio de Bachilleres del Estado de Hidalgo (COBAEH), México, Téllez campus. The inquiry that followed a qualitative perspective from action research had the participation of 35 students and their families and was carried out from March to June of the year 2020. Regarding the methodology and from the research perspective, questionnaires were used to approach the students as well as to review the grades obtained in the subject taught. The health crisis caused by the appearance and spread of SARS-COV-2 led to the use of technology for educational purposes, to cover a subject at the upper secondary education level, it was possible to use the Schoology learning management system that allowed the process to continue training of students during the health contingency. Thus, the most significant findings are presented based on school achievement, failure rate and opinions of the analysis group that made it possible to know the achievements of the intervention.

This paper describes a laboratory activity that reproduces the biological production of hydrogen sulphide to microscale and the basic study of microbial metabolism. This activity helps to high school students to understand why some types of sedimentary rocks produce a fetid smell when they are hit, such as some dolostones, and the impact on their formation.

The fixation of atmospheric nitrogen by microorganisms has significant environmental and industrial importance associated with increased in fertility and productivity in soils, supporting plants and its derived food webs. This paper shows a simple laboratory protocol, together with its theoretical foundations, in order to observe the responsible microorganisms of the nitrogen fixation in the nodules of legumes.

Molecules with antimicrobial activity, especially antibiotics, are studied in Compulsory Secondary Education. In this practical activity we show an act of serendipity, through the observation of antibiotic activity by bacteria on fungi in a sampling of heterotrophic microorganism colonies, as well as its impact and discussion on the teaching of science.

The study of sexually transmitted diseases is integrated in the Compulsory Secondary Education Curriculum. In this experience we present a simple experiment to show the HIV transmission chain, from a basic perspective, through the help of recreational science. [ABSTRACT FROM AUTHOR]

This paper presents the necessary guidelines to achieve the observation of the inhibition of sugar metabolism in yeast cells by means of the compound sodium fluoride. This activity is appropriate for the subject of Biology in Secondary Education as well as High School. [ABSTRACT FROM AUTHOR]

In this paper we show the necessary guidelines to ensure the observation, in the Biology laboratory of compulsory secondary education, of antimicrobial capacity of some compounds, especially antibiotics, and their impact on the strengthening of science education on health. [ABSTRACT FROM AUTHOR]

This communication shows the indications to achieve the success in the hydrogen microbiological production (to microscale) as an experience in the compulsory secondary education laboratory and the social repercussions as a renewable energy source. [ABSTRACT FROM AUTHOR]

This paper shows the guidelines to ensure the observation in the Biology laboratory of compulsory secondary education one of the resulting products of the glucose fermentation by Saccharomyces cerevisiae yeast, the partial study of its metabolism and the effect on the Biology discipline on the "Bachillerato" (A-level).

El artículo presenta un experimento de laboratorio para ser utilizado en la enseñanza secundaria de microbiología. Describe la construcción de la columna de Winogradsky, comenta sobre sus características didácticas y describe los cambios microbióticos y químicos observables.

The theoretical development of climate change in the Secondary Education classroom requires recreational experiences that demonstrate -in situ- different aspects of the global process. This research shows a laboratory activity, and the subsequent work of the student, to verify the reduction of greenhouse gases through the application of a basic technology, of low cost and which can be performed with material available in any school laboratory. The didactic analogy carried out between the CO2 produced by the microbial metabolism inside a closed bottle and its reaction with a strong base generating a below atmospheric pressure (as a consequence of the reaction of carbon dioxide with a base), visible with a simple U-gauge, will be the subject of debate between teacher and student, analyzing and speculating its capture with the worlwide impact of improvement in global warming.
