The working principle of this gear series product is to use a slider (linear motion) to drive the connecting rod, which then drives the crank motion, transmitting power and motion to the executing mechanism. Children aged 5 and above can learn about the basic principles of kinematics of linear motion mechanisms through operation. When operated, gears of different sizes and colors rotate consecutively at different speeds and in different directions under the force, providing children with an experience of mechanical beauty and an initial understanding of physical rotation. It also helps develop children’s comparative observational skills, hand-eye coordination, control of large and small muscles, hands-on cognitive abilities.

At the same time, it aims to transfer the rotational principles to daily life, further enhancing children’s understanding of rotational principles that exist in everyday life. This toy material can also be used as part of creating displays for the walls in the science discovery room at kindergartens.
