CAD Workspace & Drawing Units Phenomena-Based Lesson: NASA Mars Climate Orbiter Imperial-to-Metric Unit Mix-Up Presentation | Computer Aided Drafting I | Grades 9–12

This is the student-facing slide presentation that introduces the phenomenon, walks the class through observations and driving questions, and frames the evidence students will use for the Phenomena-Based Lesson in the Computer Aided Drafting I (grades 9–12) chapter CAD Workspace & Drawing Units, built around the phenomenon NASA Mars Climate Orbiter Imperial-to-Metric Unit Mix-Up. It is sold separately from the other two parts of the set.

• What's inside: Student Slide Show (editable .pptx + PDF, 23 slides); answer key / model answers for the teacher.
• Resource type: Phenomena-Based Lesson – Presentation. Format: editable Microsoft PowerPoint file plus a ready-to-print PDF.

Classroom use: Open with the phenomenon slide show, let students record ideas on the response sheet, and lead the discussion with the teacher guide. Built for Computer Aided Drafting I, grades 9–12.

Sample question“• Tier 1 Observation: How did a 4.45-to-1 unit error between pound-force seconds and newton-seconds send the orbiter about 90 km lower than planned (57 km instead of 140–150 km)?”
