Hello we 're barbara and paula from toro and burguillos. Today we went to Peña del castro that is a mountain in Sierra de la Culebra. We ate a apple in the Peña del castro.During the way we have learnt a lot of things about trees and animals and nature. Later we had lunch lentils and chicken.In the afternoon we had done a ginkana with GPS, we have known the area of the centre. We ate a sandwich of ham and some fruit. We have learned what is a fractal and saw some examples of them. We are going to the forest tonight. It´s been a very fun experience.
