Engine Components & Systems Scaffolded Phenomena-Based Lesson: Piston Thermal Expansion and Cylinder Wall Scuffing Presentation | Small Gas Engine | 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 Small Gas Engine (grades 9–12) chapter Engine Components & Systems, built around the phenomenon Piston Thermal Expansion and Cylinder Wall Scuffing. 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.

• What's inside: SCAFFOLDED Student Slide Show (editable .pptx + PDF, 17 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 Small Gas Engine, grades 9–12.

Sample question“Why would automotive engineers intentionally manufacture a piston egg-shaped and tapered when it must slide smoothly through a perfectly round cylinder bore?”
