For the last eight weeks, our seventh and eighth grade STEM students engaged in problem-solving context for which they created a design to address a particular need. In this case, the challenge was posed in a letter from a fictitious publishing company, Mobility Press, which explained that it wanted to publish a book of designs for gliding toys that children of ages 8–12 can build with assistance from an adult. The company invited the class to submit a manuscript that included drawings and plans for building the gliders, as well as instructions for how to fly them and a description of how they work. Student design teams developed two products: a gliding toy and a set of book pages that described how to build and fly the toy. Over the course of the eight weeks, a variety of activities prepared the students to develop a prototype gliding toy and a book manuscript.
