Protein Synthesis Phenomena-Based Lesson: The Molecular Riddle of Spider Dragline Silk: Stronger Than Steel, Tougher Than Kevlar Presentation | Biology 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 Biology II (grades 9–12) chapter Protein Synthesis, built around the phenomenon The Molecular Riddle of Spider Dragline Silk: Stronger Than Steel, Tougher Than Kevlar. 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 Biology II, grades 9–12.

Sample question“• Tier 1 (Observation): What chemical bond does the ricin A-chain cleave, and which organelle and specific molecular machine is disabled?”
