Geology, as a basic science within the natural sciences, is one of the key areas of knowledge for students in both, primary and secondary education. However, when teaching the areas related to geology, many doubts arise both, for teachers and students. In the case of students from the Canary Islands, who live literally on volcanic islands, geology becomes even more important and its teaching becomes mandatory. Geological concepts and processes form part of their environment, their heritage and it is also relevant in terms of the exploitation of natural resources and ecosystems around them.
During the 2021-2022 academic year, and within the educational project “Ciencia a lo grande” (Science in a big way), a number of practical workshops on volcanoes have been designed and developed in 9 primary schools in Tenerife, with the target audience being either, students or teachers, who also received specific training to be able to continue on their own the activities in the following years. The workshops were very successful, partly due to the interest around all the information surrounding the last eruption that took place in the Canary Islands archipelago, Tajogaite volcano in the neighboring island of La Palma. For this reason, there was great motivation between teachers and students. The workshops have been focused on the activation of perception and awareness of our environment, highlighting the volcanic structures that each center has around it and their morphological characteristics, differentiating them from other prominent volcanoes in the Canary Islands and all around the world. In addition, these activities aimed to develop their understanding of the different types of lava, its viscosity and the connection between this parameter and the explosiveness of eruptions, using experiences with low cost materials that were familiar, manipulative and interesting and accessible for the pupils. A set of worksheets adapted to each educational level was also created to carry out a practical activity to recognise and identify different types of volcanoes using aerial imagery. Finally, the results of the experimental activity were used to talk to students about volcanic risks according to the viscosity of the lava in the area where they live and how to act in the event of a possible volcanic emergency. In this work, the achievements pointed by teachers are also included.
