IB DP Science IA Bundle Part 2 of 2 Start to Finish Internal Assessment Resources 2026

This comprehensive 2-part bundle supports teachers and students through every stage of the IB Diploma Programme Science Internal Assessment (IA) — from choosing a topic to submitting a polished, high-quality report. Designed for Biology, Chemistry, and Physics, the bundle combines idea banks, planning tools, writing guides, assessment checklists, marking rubrics, moderation aids, timelines, and data-analysis support to make the IA process clearer, more structured, and more successful for learners at every level. This resource set is ideal for departments seeking a consistent IA system, teachers guiding students through the year, and students who need clear guidance, scaffolding, and practical tools to plan, conduct, and communicate their investigations. Please note: This is Part 2 of the complete bundle package. It contains 11 of the 23 resources available. The first 12 resources will be available in Part 1 of the bundle.

This bundle breaks it into manageable, clearly guided steps that students can follow with confidence. Supports Inquiry and Independence Open-ended idea banks paired with planning templates encourage authentic student-led investigations while reinforcing independent thinking and problem solving. Improves Quality and Readiness Tools that help students plan, write, check, and revise ensure investigations are well thought-out, fully developed, and aligned to assessment criteria. Reduces Teacher Workload Standardized rubrics, checklists, and progress trackers save time, support consistency, and free teachers to focus on feedback and conceptual development. Aligned With IB Expectations Every component supports IB academic integrity, criterion understanding, and best practices for assessment design, execution, and communication. Who This Bundle Is For • IB Science teachers guiding IA development • IB coordinators implementing department-wide IA systems • Students needing structured support from start to finish • Classes that benefit from milestone-based tracking and accountability • Learners preparing for laboratory work, analysis, writing, and reflection Whether your class is just beginning the IA journey or you’re refining submissions for moderation, this bundle provides everything needed to inspire topics, organise thinking, strengthen scientific communication, and deliver high-quality Internal Assessments with confidence.
