SOS Planet Project aims to raise awareness of the importance of taking care of our planet. Recycling, Reducing and Reusing is the key to minimize our eco footprint.  In order to save our planet, robots can be useful. In our missions and challenges robots help humans to recycle, classify rubbish, clean lakes, rescue animals and plant trees, among other actions.  Apart from robot programming, students have visited recycling plants, observatories, reservoirs, factories and natural parks. Laboratory activities helped students to understand how plants elaborate oxygen and therefore how they purity the atmosphere.
