Solid Modeling & Stress Analysis Phenomena-Based Lesson: The 'Infinite Stress' Sharp Re-Entrant Corner & The Coarse-Mesh False Pass Presentation | Engineering Design | 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 Engineering Design (grades 9–12) chapter Solid Modeling & Stress Analysis, built around the phenomenon The 'Infinite Stress' Sharp Re-Entrant Corner & The Coarse-Mesh False Pass. It is sold separately from the other two parts of the set.

Complete the set: Solid Modeling & Stress Analysis Phenomena-Based Lesson: The 'Infinite Stress' Sharp Re-Entrant Corner & The Coarse-Mesh False Pass Teacher Discussion Guide; Solid Modeling & Stress Analysis Phenomena-Based Lesson: The 'Infinite Stress' Sharp Re-Entrant Corner & The Coarse-Mesh False Pass Student Response Sheet. Scaffolded version: Solid Modeling & Stress Analysis Scaffolded Phenomena-Based Lesson: The 'Infinite Stress' Sharp Re-Entrant Corner & The Coarse-Mesh False Pass Presentation.
