ACIERTAS (Aprendizaje de las Ciencias por Indagación En Redes Transversales colaborativAS) is a project addressed to teachers in primary and first years of secondary education, promoted but the Confederation of Scientific Societies of Spain (COSCE) and funded by the Spanish ministry of Economy and Entrepreneurship.

We create teacher networks for the exchange of resources, ideas and experiences in the teaching of sciences to young children.

The ACIERTAS blog offers new public resources to everyone periodically.

By the end of the school year the best projects published by the teachers are awarded during the end of the school term Syposium.
