With the ocean pollution rapidly increasing and affecting marine life, a strong need emerges: to raise awareness about environmental and climate change challenges and develop sustainability and green skills from a very young age. This is the main aim of the RoboAquaria project, which focuses on the protection of marine environments by integrating Educational Robotics into the classroom and building teachers’ competences to use them. The project will develop a Methodological Framework for the Pilots, Guidelines for the Teachers, and validation, a RoboAquaria Toolkits and Lesson Topics and an E-Learning Toolkit and (OERs) Lesson Plans.
