BIOZONE's new integrated titles for the Next Generation Science Standards for California Public Schools (CA NGSS) have been designed and written following the High School Three- Course Model. Each of these phenomena-based titles integrates a three-dimensional approach to provide an engaging, relevant, and rigorous program of instruction. Departing from the more traditional approach of BIOZONE’s Non-Integrated Series, the Integrated Series offers a learning experience anchored in student-relevant phenomena and problems.
