This is the first lesson for this plate tectonics unit on Earth Science. Further lessons/units will be posted for sale throughout the coming 2014/15 school year. Each lesson is comprised of a main science query, followed by a reading selection. A lesson plan follows each selection with a focus on close reading, evidence-based research and writing, and vocabulary. There are generally four lessons per unit, and station activities with lesson plans are at the culmination of each unit as well.
