"These 3D printed STEM race cars are the perfect project-based learning tool to help teachers get kids excited about science, technology, engineering, math, and nutrition to boot! The racers show you how to make in this Instructable will provide an opportunity to turn almost anything (no kittens or other live things please) into a race car – allowing different sized and weighted objects to illustrate mechanical physics concepts like mass, friction, force, speed, distance, and gravity!
Will the larger, heavier squash win? Or will the lighter and more streamlined carrot cross the finish line first? What a fun way to find out!"
