  Abstract: One goal for a physics content course for pre-HS education majors is to help students develop scientific reasoning skills, particularly with respect to deductive and hypothetico-deductive reasoning. Opportunities for making such development explicit arise in two separate units that build from "Physics by Inquiry" materials. In magnetism, we use Sudoku to introduce the concept of eliminating possibilities as deduction, and we use that process to determine whether objects are permanent magnets, ferromagnetic objects, or non-magnets. When studying electric circuits, we introduce multiple possible conceptual models for electric circuits, and students are tasked with the job of "busting" them by using hypothetico-deductive reasoning. These activities allow students who are largely inexperienced with scientific reasoning to play at some fundamental processes, providing groundwork for more intense evidence-based reasoning later in the semester.
