Wooden construction set "Electric road roller", educational model

Assembled wooden educational STEM constructor "Electric Road Roller". The assembled toy moves forward, demonstrating engineering principles applied in the real world. The constructor helps children get acquainted with the basics of engineering, mechanics and electricity in the simplest way. Features: It's a construction toy, a toy and a learning tool in one. This hands-on educational toy lets kids build their own working road roller and at the same time understand the principles of mechanics, motion and electricity. Designed for young engineers and curious minds, this set provides a fun way to learn about construction equipment, power transmission and the science behind heavy equipment. During assembly, the child develops fine motor skills and precision, while the interactive learning method encourages creativity, problem solving and an interest in how things work. Made of high-quality, non-toxic wood. The wooden parts are smooth and durable, and assemble without glue. The stable construction is suitable for educational activities. Once assembled, the child can color, decorate and give it a unique look. Easy assembly: simple and clear instructions allow children to assemble the toy with minimal adult supervision, making the set suitable for both independent work and activities with parents. STEM (Science + Technology + Engineering + Mathematics) is an educational approach that integrates science, technology, engineering and mathematics into a coherent learning model to prepare the younger generation for the world of rapidly developing technologies. It is a great choice for a gift, as well as for schools and educational institutions where simple, reliable and clearly functioning educational models are needed. Operating principle: The model has an electric motor (powered by batteries), which transmits rotational motion to the wheels, so the assembled road roller can move on its own. A switch on the top of the roller turns the movement on and off. Educational value: The child is introduced to the operation of gears, electrical circuits and mechanical engineering. Purpose: for home learning, in the classroom, for project activities. Technical data: Material: non-toxic laser-cut wood; metal, plastic. Power supply: 2 AA 1.5V batteries (not included).
