Engino Discovering STEM Mechanics: Levers, Linkages, & Structures focuses on the mechanics of simple machines and the strength of structures. Young mechanics explore first-, second-, and third-class levers, investigate linkages (including parallel motion) to convert and transfer movement, and use a pantograph to scale drawings while preserving proportions.

On the structures side, they learn types of forces and loads, bridge types, and how triangulation stiffens frames. Concepts stick through hands-on experiments (e.g., transforming a single-beam bridge into a sturdier double-deck and testing rigidity) and self-check quizzes.

Instructions are hybrid with printed instructions for 1 model, plus 16 online 3D builds in kidCAD (3D Viewer) so learners can rotate and zoom each step for error-proof assembly.

Emily ★★★★★

The linkage models actually move the way they're supposed to, which surprised me after some flimsy building kits we've tried. My son built the seesaw first and spent an hour just testing how the lever arm changes with weight. Sixteen models means this thing will keep him busy for weeks.

Evelyn X. ★★★★★

Bought this for my 9-year-old and he knocked out the first- and second-class lever models in one afternoon without any help from me. The instruction booklet actually explains the physics behind each build instead of just showing pictures, which I appreciate. Sixteen models means it'll keep him busy

Grace ★★★★★

The linkage pieces snap together tight enough that the models don't wobble, which surprised me since I've had other building sets fall apart mid-play. My son worked through the lever models in one afternoon and kept explaining fulcrums to me at dinner.
