This gear series product is a scientific toy for children aged 5 and above to manually operate gears, driving 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, colors, and shapes rotate at different speeds under the applied force, providing children with an experience of mechanical beauty and an initial understanding of gear rotation. It also helps develop children’s comparative observational skills, hand-eye coordination, fine motor skills, and hands-on cognitive abilities.

At the same time, it aims to transfer the principles of rotation to daily life applications to further enhance children’s understanding of gear rotation principles present in everyday situations. This toy material can also be used as part of creating wall displays for the science discovery room in kindergartens.
