Additive Manufacturing & Prototyping Scaffolded Phenomena-Based Lesson: The 65 N Z-Delaminated Hook vs. The 340 N Flat-Printed 5-Shell Hook & The Warped ABS Enclosure Presentation | Introduction to Technology and Engineering | 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 Scaffolded Phenomena-Based Lesson in the Introduction to Technology and Engineering (grades 9–12) chapter Additive Manufacturing & Prototyping, built around the phenomenon The 65 N Z-Delaminated Hook vs. The 340 N Flat-Printed 5-Shell Hook & The Warped ABS Enclosure. This scaffolded version adds sentence frames and extra supports for students who need them. It is sold separately from the other two parts of the set.
