In Unit 2, students continue to read the anchor text, The Boy Who Harnessed the Wind, beginning at chapter 11. As William formulates a plan for a windmill to generate electricity and ease some of the burdens caused by the famine, students examine how he applies design thinking to solve his problem. Using a graphic organizer to collect evidence of William's problems and solutions, students build understanding of the cyclical nature of design thinking and the way the author develops this key idea with specific details. In the second half of the unit, students finish reading the anchor text and launch their research project.Inspired by a curated list of TED Talks, students choose a different invention designed to solve a critical problem.
