The sea classes combine both observations (on the beach, in the marshes, the forest, etc.), learning activities and water activities. For example, thanks to the educational mediators at the nearby Biotopia center - a venue devoted to discovering the coast and the forest - students discover the dune ecosystem, a living, mobile, fragile environment, which is shaped by the winds and sea currents, or sea-wrack and the role it plays. They also take part in Climate Fresk, a collaborative workshop to raise awareness of climate change, or they can check out the panoramic view from the Kulmino platform (70 m above the ground), which offers a bird’s-eye view of the landscape. During their stay, students can also try their hand at watersports, such as canoeing, paddleboarding, or sailing a catamaran. Finally, they are given an introduction to professions related to the coast, through the professionals who work with the student throughout their stay (e.g. educational mediator, nature events organizer, ornithologist), and the entertaining system created by the association “Crée ton Avenir” that focuses on the types of professions, and an introduction to career choices with the older students.
