Catapult Challenge
Introduction to Engineering Design (IED) students channeled their inner medieval engineers with an engaging catapult challenge to test their creativity and technical skills. Led by PLTW instructor Mr. Sward, the class is designing, building, and optimizing mini catapults to launch projectiles with precision and efficiency, all while exploring fundamental principles of design and mechanics. "This challenge embodies the essence of engineering—turning ideas into functional solutions through trial and error," explains Mr. Sward. "It's inspiring to see our students apply math, physics, and collaboration in a fun, competitive way, all while reflecting our Lutheran commitment to thoughtful creation and problem-solving."
Working in small teams, students began with research and sketches, then used tools like Onshape for 3D modeling and rapid prototyping with materials such as popsicle sticks, rubber bands, and 3D-printed components. The goal was to maximize distance and accuracy while adhering to constraints like size limits and material budgets, and then learn key IED concepts including the design process, iteration, and failure analysis.
Prototypes will be tested in a class-wide competition. As these young Vikings refine their catapults, they're not just building machines—they're building futures in STEM!
