A compilation of popular “Tried and True” columns originally published in the award-winning journal Science Scope, this new book is filled with teachers’ best classroom activities—time-tested, tweaked, and engaging. These favorites are organized by topic, including physical science, life science, Earth and space science, and instructional strategies. Activities like "Investigating Ecosystems in a Biobottle," "Balloons and Newton’s Third Law," and "Helicopter Seeds and Hypotheses …That’s Funny!" are hands-on lessons that pique students’ interest and demonstrate important science concepts. Teachers will appreciate the accompanying activity worksheets, visual aids, and connections to the national standards. These ageless activities will fit easily into your middle school curriculum and serve as permanent go-to resources when you need a tried-and-true lesson for tomorrow.
