This is a Intro To Gears Experiment Kit that's produced by the good folks over at Thames And Kosmos. They make some of the neatest building sets on the market today.
Intro to Gears is a fun and engaging way to explore the many amazing things gears can do. With many big and small gears, kids can learn about gear ratios, gear trains, transmissions, power, and torque. The full-color, step-by-step manual explains to parents and adult supervisors how to build the models and how information can be presented to kids.
