This project focuses on designing and building an interactive mechanical exhibit that helps children ages 8–12 learn basic engineering concepts through hands-on experience. The motivation comes from the lack of engaging, physical STEM tools in many under-resourced educational spaces, where students often don’t get the chance to explore how everyday mechanisms actually work. The exhibit, designed to fit within a 2’ × 2’ × 6” frame, functions like a Rube Goldberg machine, guiding a metal ball through a sequence of mechanisms that demonstrate concepts such as gear ratios, mechanical advantage, projectile motion, angular momentum, conservation of energy, and energy loss. Users will directly interact with the system by turning a hand crank to lift the ball using a geared bucket elevator and pulling back a spring-loaded plunger to launch it along different paths. These interactions are meant to make abstract ideas more intuitive by letting students feel and control the mechanics themselves. So far, the project has progressed through concept development, sketching, and early prototyping of key components like the gear system and launcher, which have shown that the basic design is workable. Initial testing has also helped identify areas for improving ease of use and consistency. The final goal is to create a durable, engaging exhibit that not only captures attention but also helps students understand and explain how energy moves and changes within a system, supported by simple visuals and opportunities for feedback.
