Science A-Z provides multi-leveled text to smoothly integrate science and literacy. The units are distributed over four scientific domains: Life, Earth and Space, Physical, and Process Science, based on the grade range at which the topic is taught in most states. Each unit has resources at three reading levels: low •, mid ••, and high •••. These comprehensive resources can be used to create a core science program, or to supplement existing science curriculum.
