This gear series product is a scientific toy designed for children aged 3 and above to manually operate gears and drive the rotation of various gears. Through playing with it, children can learn about the continuous transmission of gear teeth and the basic principles of mechanics. When operated under the same force, gears of different sizes and colors rotate consecutively at different speeds, providing children with an experience of mechanical beauty and an initial understanding of physical rotation. It also helps develop children’s comparative observational skills, eye-hand coordination, control of large and small muscles, hands-on cognitive abilities, and color vision 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.
