This gear series product is a scientific toy for children aged 5 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 kinematics. When operated, gears of different sizes and colors rotate consecutively at different speeds under force, providing children with an experience of mechanical beauty and an initial understanding of the physical conditions for rotation. It also helps develop children’s comparative observational skills, hand-eye coordination, control of large and small muscles, and hands-on cognitive abilities.

At the same time, it aims to transfer the rotational principles to daily life, further enhancing children’s understanding of the relationship between rotational speed and obstacles 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.
