The province of Tierra del Fuego, Antarctica and South Atlantic Islands is the southernmost province of Argentina. Its capital is the city of Ushuaia, also known as the southernmost city in the world. The secondary school presents challenges such as low levels of promotion, overage, repetition and dropout. With this in mind, it is important to think about programmes to improve teaching, such as the Science Fair Programme. In relation to science teaching in Tierra del Fuego, it is worth asking how they conceive the study of science-related subjects; what is the link they establish between the study of science and the preservation of the environment and the care of their health; how do they perceive science classes in relation to their interest in studying; what is their opinion about science fairs and their participation in a school investigation to be exhibited at the science fair; and what is their opinion about science fairs and their participation in a school investigation to be exhibited at the science fair. These are the questions that motivate us to carry out this research in order to obtain concrete data that will allow us to make decisions in the future on the basis of certainty about what is happening.
