Deluxe Gear Box Set

Students discover the physics behind gears and pulleys as they work to construct a racecar, small tractor, windmill, and even a solar-powered vehicle! With this kit, students are introduced to the fundamentals of design and technology before progressing through more complicated concepts like gear reduction and its effects on force and motion. Brightly colored plastic gears and chains make it easy to understand how individual pieces work together. When students project ideas included in the workbook, have them build something straight from their imaginations! Kit includes 744 pieces and a 25-page instruction guide. Kit requires 1 C battery (not included). See full contents list below. Grades 4 and up.
