DIY wooden educational STEM kit “Elevator”. This construction kit helps children learn the basics of physics and engineering in the simplest and most engaging way.  Features: This is a construction kit, toy, and educational tool all in one. The educational set allows future engineers to design, assemble, and operate their own working miniature elevator. The toy fascinates young builders with an engaging combination of engineering ingenuity and educational fun. During assembly, children develop fine motor skills, precision, and engineering thinking. The model is made from high-quality, child-safe materials. Its sturdy construction withstands many trips up and down, ensuring safe and enjoyable play. The model is also suitable for educational activities. Young engineers can paint and decorate their elevator to give it a unique style. Easy assembly: simple and clear instructions allow children to assemble the toy with minimal adult supervision, making the kit suitable for independent work or activities together with parents. STEM (Science + Technology + Engineering + Mathematics) is an educational approach that integrates science, technology, engineering, and mathematics into a unified learning model to prepare the younger generation for the rapidly developing world of technology. This is an excellent gift choice, as well as a useful kit for schools and educational institutions where simple, reliable, and clearly functioning teaching models are needed.  Working principle: The elevator is powered by a direct current (DC) motor, which raises or lowers the elevator cabin through a pulley and rope system. The battery holder has an integrated control panel with buttons used to control the direction of movement. Motor operation: the toy demonstrates how electrical energy is converted into mechanical energy. Changing current direction: by using the control panel, children learn that reversing the electrical polarity causes the motor to rotate in the opposite direction (so the elevator rises or descends). Pulley system: children can practically see how a rope and wheel (pulley) help change the direction of force and lift loads. Force and movement: children understand how rotational force (from the motor) is converted into linear movement (up/down). Weight and balance: during construction, children observe that the cabin must move smoothly and not hit the sides, teaching the principles of stability. Problem-solving: if the elevator jams or does not move, children must analyze the cause: perhaps the screws are too tight, the rope has loosened, or there is poor wire contact. Educational value: the model practically teaches principles of physics and electrical engineering: force transmission through pulleys, conversion of energy into movement, and circuit control by changing current direction. Purpose: learning at home, in the classroom, and for project-based activities.  Technical specifications: Material: high-quality non-toxic laser-cut wood; metal; plastic.
