General aims The general objective is to make the students understand the strong interdependence between photosynthesis and respiration, processes that are the basis of the natural carbon cycle. Photosynthetic organisms using solar energy convert carbon dioxide and water into carbohydrate molecules, such as sugar and starch, with the release of molecular oxygen. Living organisms that are capable of using oxygen reverse this process with respiration: in fact, thanks to the presence of oxygen, they use carbohydrates and other organic molecules in order to produce the energy necessary for their life, simultaneously eliminating water and carbon dioxide. Linguistic aims • To improve language skills in L2 • To enrich scientific vocabulary • To know how to move from one linguistic register to another • To produce clear and coherent texts in L2 • To summarize written texts Subject specific aims • To write the general equation of glucose oxidation • To compare the energy gain resulting from complete oxidation of glucose and fermentation • To describe the role of NADH and FADH2 • To summarize the process of glycolysis by highlighting the most important reactions and compounds • To explain the structure of the mitochondria • To describe how the formation of acetyl-CoA takes place • To analyze the main stages of the Krebs cycle • To summarize how NADH's high-energy electrons drop energy levels along the transport chain • To explain the fundamental role of oxygen at the end of the final electron transport • To describe the mechanisms that regulate chemosmotic processes Target group age 15-16 age Level of competence in English (CEFR) B1 Time required to use the resource with the students 4h 3 h resource analysis 1 h comparison and discussion How to use it (prerequisites: oxide reduction reactions) The teacher presents the resource and explores the topic using suitable images After this, the students are divided into groups and invited to work on them with a flipped classroom approach. In the next class meeting each group, using both the material provided by the teacher and doing personal research, involves the other groups through quizzes, crossword puzzles, discussions. The material provided by the teacher will include images closely related to the video, but more explanatory. All the work carried out will be included, then, in the final one which will include all the material related to the biogeochimical cycle of carbon, the green house effect and global warming. The work will be presented to different classes Possible difficulties for the students The difficulties are represented by understanding the mechanisms of biochemical reactions, it is necessary to reread and listen to the resources several times and work on the images provided and explained by the teacher
