energy blocks

Common components include LED modules and plates, battery modules, sound-activation modules, motors and gear modules, and generator or hand-crank elements — together these let you add lights, sound and motion to builds.

Power varies by kit: built-in battery modules, external batteries (AA or 9-volt), hand-crank generators, and in some projects no batteries are required.

Most sets target ages 8 and up, though some motor-focused or single-student kits list minimum ages around 5 years.

Many kits include online animated curriculum, teacher guides, lesson plans, quizzes and answer sheets to support classroom or homeschool STEM instruction.

Certain sets use patented, tin‑plated conductive parts that form 3D circuit paths through the blocks, allowing integration of LEDs and other components without separate wiring.
