Beam Deflection & Cantilever Loads Scaffolded Phenomena-Based Lesson: The 9× Stiffer Edge-Turned Plank. The 8× Double-Span Sag & The 16× Cantilever Penalty 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 Beam Deflection & Cantilever Loads, built around the phenomenon The 9× Stiffer Edge-Turned Plank. The 8× Double-Span Sag & The 16× Cantilever Penalty. 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: Beam Deflection & Cantilever Loads Scaffolded Phenomena-Based Lesson: The 9× Stiffer Edge-Turned Plank. The 8× Double-Span Sag & The 16× Cantilever Penalty Teacher Discussion Guide; Beam Deflection & Cantilever Loads Scaffolded Phenomena-Based Lesson: The 9× Stiffer Edge-Turned Plank. The 8× Double-Span Sag & The 16× Cantilever Penalty Student Response Sheet.

Sections: Section 1: Three-dimensional Learning Alignment (ngss); NGSS Dimension; Scaffolded Three-dimensional Learning Goal; Learning Goals; Section 3: Scaffolded Science Talk Moves Matrix; Scaffolded Talk Move; Verbatim Facilitation Prompt & Talk Goal; Everyday Student Misconception (flawed Claim). Sample item: “Question 3: Comparing δ_SS = PL³/(48EI) and δ_cant = PL³/(3EI). Why does doubling span length (2L) multiply sag by 8×. And why does a cantilever deflect 16× more than a simply supported beam of equal ”
