At 09:00 we have started the activities in the physics lab for the Practical Experience II. The specialized educators of the Canal Educa Foundation have visited us to conduct experimental sessions. The activity began with an introduction in which contents related to the integral water cycle, its physicochemical properties and work in the laboratory are treated. Then the students have been divided into working groups to carry out the experiments. Each group performed 3 or 4 different experiments. The tests carried out have been: Universal solvent / surface tension, osmosis / reverse osmosis, suspended solids, nitrates / phosphates, free chlorine / total chlorine, conductivity. To conclude, the importance of good practices in the use of water has been emphasized in order to avoid spilling substances in it that could hinder its treatment. After that students went for a walk through Alcalá while the Coordinators Meeting In the afternoon...
