IB DP Biology | D4.2 Stability and change | Lesson Walkthrough Bundle

About this resource

A complete 6-lesson walkthrough bundle for D4.2 Stability and change. Includes the matched student activity packs and separate teacher answers.

Course levels: 4 lessons for both SL and HL; 2 additional HL-only lessons. HL-only lessons are identified individually in the contents guide.

Duplicate-purchase note: these same lessons are also included in Theme D and the Complete 180-Lesson Collection. They are not additional resources if you already own those collections or the individual lessons.

• 6 teacher walkthroughs, 6 student activity packs and 6 separate answer documents.
• Every lesson document is supplied in editable DOCX and print-ready PDF: 36 lesson documents in total.
• A PDF contents guide, a bundle cover and the classroom assets/credits supplied with the constituent lessons.
• Numbered lesson folders keep student materials separate from teacher-only answers. Large collections use independently usable ZIP parts with complete lessons.

Bundle price: US$19.15, 20% below the combined US$23.94 individual-lesson price.

These are the same lesson resources offered individually, collected without rewriting their content. They are not additional lessons. Required practical work, fieldwork and live research remain explicit teaching dependencies; separate IA, collaborative-sciences-project and practical-course requirements are not replaced.

Independently authored teaching materials, not official IB examination papers or markschemes and not endorsed by the International Baccalaureate.
