This gear series product is a scientific toy for children aged 5 and above to manually operate gears in different positions, causing the active parts in the gears to move continuously while the driven parts move intermittently, creating a rotating gear mechanism. Through playing with it, children can learn about the intermittent motion principle of cage gears and the basic principles of kinematics. When operated, gears of different positions, sizes, and colors intermittently rotate under the same 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, motor skills, and hands-on cognitive abilities.

At the same time, it aims to transfer the rotational principles of cage gears to daily life, further enhancing children’s understanding of complex 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.
