NATIONAL GEOGRAPHIC Da Vinci Model Kit – Catapult Kit
Overview: This kit assembles three functional machines—a Ballista, a Bombard, and a Catapult—to demonstrate early artillery concepts. It includes 15 projectiles and six targets to test aim and trajectory. The parts are laser-cut from wood, and the package provides clear, simple instructions that avoid the need for extra tools. The project duration for each model typically stays within a few hours, making it suitable for a focused weekend project or a series of build sessions.
What it teaches: Students explore simple machines, levers, geometry, timing, and mechanical advantage. The kit’s hands-on nature supports kinesthetic learners while illustrating historical engineering developments. The included targets and projectiles help learners quantify accuracy and adjust designs, reinforcing iterative thinking and measurement skills.
Why teens will benefit: The multi-model format encourages planning and experimentation. Learners can assess which machine design delivers the best range or stability and then compare differences in arm length, base support, and tension from rubber bands. This kit pairs well with lessons in physics and history-driven engineering narratives.
Discovery Model Engine Building Kit
What’s inside and what it teaches
Designed to resemble a classic car engine, this kit features a four-cylinder setup with interactive cranks, pulleys, belts, and exhaust valves. Teens can observe the pistons moving, connect cables to a battery pack, and watch the engine fan respond. LED lights add a visual layer to the demonstration, making the learning experience engaging as the model “comes to life.”
Skills developed include mechanical reasoning, spatial thinking, and sequencing. The kit emphasizes how engines convert fuel or electrical energy into motion, a foundational concept in robotics and automotive technology. It also offers a hands-on pathway to discuss thermal dynamics and machine efficiency in a tangible way.
Why it benefits teens: This kit appeals to those curious about how machines work and those seeking a tactile way to translate theory into observable outcomes. It supports project-based learning goals and can be paired with basic electronics and control concepts to extend the activity beyond assembly.
