From their site, "ReadWorks provides research-based units, lessons, and authentic, leveled non-fiction and literary passages directly to educators online, for free, to be shared broadly."
Even though this website is for elementary school, the new grade 8 material would work in the high school Science and English classrooms. Registration is free and there is a myriad of material for teachers. There are 12 new grade 8 passages in science to teach reading comprehension. Such passages as "Wetlands and Habitat Loss", "A Bird with Many Beaks" and "Everyday Compound or Poison", to name a few. Included with these passages are some multiple choice questions and an extended response question. Also included are solutions.
