La Laja beach, in Las Palmas de Gran Canaria, was recently transformed into an open-air classroom for students participating in the EduSen educational project (Marine Sensors: From the Classroom to the Conference), an innovative initiative led by the Oceanic Platform of the Canary Islands (PLOCAN).
A total of 175 students from 10 schools across the island of Gran Canaria took part in this field trip alongside their teachers. The activity forms part of a broader project aimed at bringing marine science into the classroom and fostering ocean literacy among younger generations.
Throughout the day, students put into practice the knowledge they had previously acquired in class through a range of scientific activities. These included observing both the abiotic and biotic environments of the coastal area, where they identified various physicochemical factors and organisms, gaining a deeper understanding of marine ecosystems. They also measured water parameters such as temperature and TDS-conductivity levels using Arduino-compatible kits that they had assembled themselves in the classroom. This hands-on experience enabled students to become familiar with technological tools used in real scientific research.

Another highlight of the excursion was the collection of plankton samples and their subsequent analysis using the PlanktoScope, a device that facilitates the visualization of planktonic organisms. Through this activity, students were able to observe firsthand the microscopic biodiversity present in the marine environment.
The EduSen project aims to promote environmental education in the Canary Islands by encouraging ecological responsibility, particularly in the marine context. Through practical experiences such as this, the initiative seeks to inspire and consolidate scientific vocations while raising awareness among students about the importance of ocean conservation.
This initiative is funded by the Department of Education and Youth of the Cabildo de Gran Canaria, which supports innovative education aligned with current environmental challenges.
