2 - "What is the specific activity to be carried out with students?"
The main result of the activity will be a video -or more- with students reciting the selected poetic fragment in the language in which it was originally written. Students, therefore, will recite the poem in their language, and AT THE SAME TIME they will make some gestures (the gestures can be made by all students, it may be also only one doing gestures while the others speak, or even each student may be making a gesture with scenery for this poem in particular, that comes down to the creativity of individual teachers and their students).
