NSU University School Viewpoint Fall/Winter 2017

VIEWPOINT n 11 Students then shared a link to their planning page with classmates so they could collaborate, as well as with Carnaggie, who monitored students’ progress. Once plans were approved, students began submitting their designs to the 3-D printer. “After the cars were printed, students needed to rely on their problem-solving skills, as their original plans do not always work. We are melting plastic, so there is sometimes a droop to the holes or roughness to the axles. Some students use a drill to make the holes more round and/or use sandpaper to smooth the axles in order for the axles to fit through the holes in the body of the car,” Carnaggie said. “During this hands-on project, students learn the design and redesign process using isometric and orthographic drawings, testing and retesting modes of energy to make the car move on its own, how to use a 3-D printer properly, advantages of 3-D printing, and the import- ance of measurement. This is engineering at its best,” she concluded. n Gregory Toussaint, left, and Nolan Hen- derson work together on their 3-D cars.
