This project will be held with 2nd ESO students. As the Schedule doesn't allow to work with the 3 groups of this level, we have implemented it just in 2nd B, which is composed of 28 fantastic pupils, including five newcomers. The project involves the areas of Natural Science, Physical Education, Maths and Tutorial Class. Although Natural Science is not a curricular content in that level, environmental questions and meal routines are usual topics in our Tutorial Classes. So, introducing these knowledge is necessary to give sense to the whole Project.
