IB DP Sciences IA Investigation Planning Checklist 2026

IB DP Science IA Bundle Part 1 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 1 of the complete bundle package. It contains 12 of the 23 resources available. The remaining 11 resources will be available in Part 2 of the bundle.** Part 2 can be found here: [https://www.tes.com/teaching-resource/ib-dp-science-ia-bundle-part-2-of-2-start-to-finish-internal-assessment-resources-2026-13404166](https://) What’s Included in This Complete Bundle 1. Idea and Topic Banks • Extensive subject-specific IA idea databases for Biology, Chemistry, and Physics • Hundreds of investigation prompts to inspire research questions • Suggestions for experimental, database, simulation, survey, and hybrid investigations 2. Planning and Proposal Tools • Structured IA planning templates for research questions, variables, methodology, risk assessment, and data planning • Milestone timelines with automatic date calculations • Progress tracking to help students manage workflow across months 3. Writing Guides and Worksheets • Conclusion writing support and frameworks • Evaluation writing lesson and templates • Worksheets for significant figures, uncertainty propagation, graph interpretation, regression (R²), and more • Student self-assessment checklists to confirm completeness before submission 4. Assessment, Marking & Moderation Tools • Teacher marking rubric aligned with IB criteria • Standardized marking and moderation system with analytics dashboards • Double-marking support and variance tracking • Calibration records and moderation logs Why This Bundle Is Valuable Simplifies a Complex Process The IA is one of the most challenging components of IB Science. 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.
