This bundle has a detailed step-by-step guide to get students familiar with SketchUp. Students will model a simple chassis and wheels for their Mars Rovers. Once your fledgling engineers are comfortable with SketchUp, turn them loose to model the rest of the rover. If they need help or inspiration, they can use the Mars Rover Expansion Pack recipe cards. These provide sequenced steps to add a cargo box, bench, dashboard, and windshield.
