Fidget spinners have become a fixation among school children and adults. Pappas (2017) hails spinners as both a boon to stress relief and a constraint on the ability to focus in persons with Attention-Deficit/Hyperactivity Disorder (ADHD) or autism. Spinners can be a distraction in school classrooms, to the point that many schools have banned them. However, the authors found them to be an engaging hook to interest students in engineering design. This article describes an exploration third graders undertook to develop basic concepts regarding force and motion as they engineered their own simple spinners.
