Power Tool Safety Procedures Phenomena-Based Lesson: The Circular Ripping Blade Reactive Force Kickback & Pinch Boundary Dynamics Presentation | Agricultural Mechanics | 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 Agricultural Mechanics (grades 9–12) chapter Power Tool Safety Procedures, built around the phenomenon The Circular Ripping Blade Reactive Force Kickback & Pinch Boundary Dynamics. It is sold separately from the other two parts of the set.

• What's inside: Student Slide Show (editable .pptx + PDF, 22 slides).
• 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 Agricultural Mechanics, grades 9–12.

Sample question“• Tier 1: What vector forces are exerted by the upward-moving rear teeth of a circular saw blade compared to the downward-cutting front teeth?”
