Wooden construction set "Young Inventors' Laboratory", 5 pcs. educational models

The Educational STEM Senior Kit is a wooden model building kit designed to give children hands-on experience in science, technology, engineering and mathematics. The kit includes 5 projects: a piano (music box), a crawler robot, an excavator, a Ferris wheel and an elevator. Recommended for children aged 8 and up. Features: This is a construction set, toy and educational tool in one. By constructing and testing models, children learn through experience, experiment and better understand the basic principles of physics and mechanics. Each model allows you to practically understand how various mechanisms work, the principles of movement, sound, electricity, hydraulics and energy transfer. During assembly, fine motor skills, spatial perception, understanding of geometry, a sense of symmetry and accuracy are developed. Practical activities promote creativity, patience and self-confidence, as the child creates real working mechanisms with his own hands. Made of high-quality, child-safe materials. Wooden parts are smooth, durable and can be varnished or painted in the child's favorite colors. Clear instructions allow children to assemble all the models in the set with minimal adult supervision, making the set suitable for independent work, activities with parents, schools and educational institutions. 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. This practical STEM learning tool helps to apply theoretical knowledge in reality. The child learns to analyze why the model works or does not work, looks for solutions and independently corrects errors. 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. Model descriptions: Piano (music box): The model operates with a mechanism turned by a handle, which rotates a cylinder with protrusions. The cylinder touches metal plates or reeds as it moves, creating ringing sounds. The child becomes familiar with the origin of sound, vibration, the conversion of mechanical motion into sound, and the operation of musical mechanisms. Crawler robot: The model is powered by an electric motor, which creates a vibrating motion through an eccentric mechanism. Due to the distribution of the center of gravity and the design of the wheels, the robot moves forward and changes direction when hitting obstacles. The child understands the principles of vibration, friction, balance, and mechanical motion. Excavator: The model is controlled by a hydraulic system of syringes and tubes. By pressing the control syringes, water pressure is transmitted to the working cylinders, which move the boom, handle, bucket, and turning mechanism. The child becomes practically acquainted with Pascal's law, hydraulics, force transmission, and the operation of levers. The Ferris wheel is rotated by an electric motor, the axis of which is connected to the main axis of the Ferris wheel by a tensioned rubber. As the motor rotates, the movement is transmitted to the wheel through a belt drive, so it rotates evenly. The cabins remain vertical due to gravity and freely moving mounts. The child practically gets acquainted with the operation of the belt drive, rotational movement, axle transmission, balance and the effect of gravity. The elevator is driven by a DC motor, which raises or lowers the cabin through a pulley and rope system. The control panel allows you to change the direction of movement. The child practically gets acquainted with the electrical circuit, the operation of the motor, pulleys, changing the direction of force and controlling mechanical movement. Educational value: 1. Knowledge of the laws of physics Each model helps to understand different principles of physics. The music box introduces sound vibrations and resonance. The caterpillar robot shows the effects of vibration, friction and balance on movement. The Ferris wheel allows you to observe rotational movement, gravity and balance. The elevator explains the transmission of force through pulleys, and the excavator reveals the operation of hydraulic pressure. 2. Development of engineering thinking By assembling models, the child learns to correctly connect parts, ensure the stability of the structure and understand the operation of mechanisms. The excavator shows the operation of levers and hydraulic systems, the elevator - lifting mechanisms, and the Ferris wheel - how stable rotating structures are designed. 3. Development of technological literacy The set introduces wires, battery boxes, motors and mechanical transmission elements. The elevator and the caterpillar robot help to understand how electrical energy is converted into movement. The music box shows how mechanical devices can perform complex functions without electricity. 4. Mathematics in practice Construction develops spatial thinking, geometric perception and accuracy. When assembling a Ferris wheel, it is important to maintain symmetry, in an elevator - verticality and parallelism, and in an excavator - appropriate lever angles and movement amplitudes. 5. Problem solving and creativity Children learn to analyze why a model moves incorrectly or does not work. If an elevator gets stuck, a Ferris wheel rotates unsteadily or an excavator's hydraulics do not work, they have to find the cause and eliminate it. This develops logical thinking, patience and self-confidence. Technical data: Material: high quality non-toxic laser-cut wood; metal, plastic.
