Cala Sant Francesc beach is wide and very beautiful. On the right there is a stone wall and if you look on the left, there is a rocky area and a door which has access to a path along the coast. In the middle, there is a sandy beach where people can sunbathe and go for a swim.

We wrapped the thermometer in order to protect it and then we attached it to one end of the cane. The cane was provided by a teacher. It was from the forest near the school.

After creating the graphic we realized that the tidal range was related to the lunar phases.

Thanks:
 to the FP-initial PQPI and their teacher: they arranged the Secchi disk for us. We want to express our gratitude for creating this amazing material for us.

And finally we would like to express our gratitude to Joan Musoll for going with us in his rubber dinghy to help us take the Secchi disk data.
