In the third session, the classroom has been decorated as if it were a real sea bed. First, the students perform, all together, an introductory activity that involves moving around the classroom as if they were divers, in order to find various marine items hidden everywhere ( shells and other sea animals). Then, using various visual elements such as pictures, posters and objects related to the sea, students act out a short adapted dialogue in pairs, which is a fun and unusual scene that takes place under the sea. The final proposal is to make a fish stick puppet.
