The Spanish education system is undergoing a profound transformation due to the implementation of a new education law. In this work, we will make a comparison between the old and new educational laws about the content related to Geology in primary education. Moreover, the Spanish curriculum will be compared to the New Generation Science Standards (NGSS), since this is the reference curriculum used by the largest American research institutions (NASA, USGS, NPS, Universities, ...). This study will analyze the specific curriculum that will be implemented in the Canary Islands (Spain). In this sense, we will pay special attention to the treatment of the volcanic phenomenon and the use of the Canarian geological resources. The Geology of the XXI century is characterized by its interdisciplinarity, where subjects such as Physics, Mathematics, Chemistry, Ethics or Engineering play a fundamental role. Is this taken into account in the new education law? Finally, we will offer a series of didactical tips to give students and teachers of primary education a broader, engaging and motivating vision of Geology that awakens their curiosity towards Earth Sciences.
