Introduction to Organic Compounds Phenomena-Based Lesson: Vast Hardness and Electrical Conductivity Disparity Between Pure Carbon Allotropes Diamond and Graphite Presentation | Chemistry II | 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 Chemistry II (grades 9–12) chapter Introduction to Organic Compounds, built around the phenomenon Vast Hardness and Electrical Conductivity Disparity Between Pure Carbon Allotropes Diamond and Graphite. 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 Chemistry II, grades 9–12.

Sample question“How can two macroscopic substances built from 100 percent identical carbon atoms display polar opposite physical and electrical properties?”
