Casting & Molding Processes Scaffolded Phenomena-Based Lesson: The Hollow Shrunken Gear Hub, The Flashed 150-Ton Injection Mold & The 3D-Printed Conformal Cooling Breakthrough Presentation | Manufacturing Systems | 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 Manufacturing Systems (grades 9–12) chapter Casting & Molding Processes, built around the phenomenon The Hollow Shrunken Gear Hub, The Flashed 150-Ton Injection Mold & The 3D-Printed Conformal Cooling Breakthrough. 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.

Complete the set: Casting & Molding Processes Scaffolded Phenomena-Based Lesson: The Hollow Shrunken Gear Hub, The Flashed 150-Ton Injection Mold & The 3D-Printed Conformal Cooling Breakthrough Teacher Discussion Guide; Casting & Molding Processes Scaffolded Phenomena-Based Lesson: The Hollow Shrunken Gear Hub, The Flashed 150-Ton Injection Mold & The 3D-Printed Conformal Cooling Breakthrough Student Response Sheet. Original version: Casting & Molding Processes Phenomena-Based Lesson: The Hollow Shrunken Gear Hub, The Flashed 150-Ton Injection Mold & The 3D-Printed Conformal Cooling Breakthrough Presentation.

Sections: Section 1: Three-dimensional Learning Alignment (ngss); NGSS Dimension; Scaffolded Three-dimensional Learning Goal; Section 3: Scaffolded Science Talk Moves Matrix; Scaffolded Talk Move; Verbatim Facilitation Prompt & Talk Goal; Everyday Student Misconception (flawed Claim); Scientific Evidence & Intuitive Correction. Sample item: “According to Chvorinov's Rule (t = B[V/A]^2), a Riser must have a larger ___________-to-Surface-Area ratio (V/A) than the casting so the riser freezes last.”
