REVIEW:
Give your students the opportunity to learn about the history of the NASA space program while learning to use CAD (computer-assisted drafting and design) software. A "lite" version of the software is available for download from the site. SpaceCAD offers a series of 11 lessons, slide shows, interactive quizzes, and design projects that are based on authentic technical drawings from NASA. Students will learn the basics for creating two-dimensional drawings, orthographic projections of three-dimensional objects, sectional views, and isometric drawings. One lesson covers the steps that engineers take in the design process. Students can apply their newly acquired skills to complete the design challenges, which include designing a lunar rover, a Mars lander, or a satellite.
