The Pitsco 31901 TETRIX Gear Pack includes aircraft-grade aluminum gears for students in grades 9-12 building TETRIX robotics projects. The gears are made of aircraft-grade aluminum for durability; aluminum resists corrosion and tarnishing, and is lightweight. The pack includes 39028 TETRIX 40-tooth Gears, 39086 TETRIX 80-tooth Gears, and 39085 TETRIX 120-tooth Gears for building gear trains and other robot mechanisms. TETRIX products reinforce science, technology, engineering, and mathematics (STEM) concepts for students in grades 9-12 studying robotics and building a working robot that demonstrates engineering, simple machines, force, and Newton's laws of motion. A gear transmits rotational force in a mechanical device or tool, and can be used to build a robotics project, among other mechanical applications.

Science education products incorporate applied math and science principles into classroom and homeschool-based projects. Teachers in pre-K, elementary, and secondary classrooms use science education kits and products alongside science, technology, engineering, and math (STEM) curriculum to demonstrate STEM concepts and real-world applications through hands-on activities. Science education projects include a broad range of activities, such as practical experiments in engineering, aeronautics, robotics, energy, chemistry, physics, biology, and geology.

Pitsco Education develops K-12 science, technology, engineering, and math (STEM) curriculum, educational kits, and classroom tools. The company, founded in 1971, is headquartered in Pittsburg, KS.
