What Is Included
• Complete conclusion writing guide with templates and worked examples
• Subject-specific frameworks for Chemistry, Biology, and Physics
• Three model conclusions demonstrating high-level performance
• Step-by-step structure with paragraph guidance
• Quality checklists and common pitfalls
• Editable Word format
Understanding the Criterion
The guide explains how conclusions are assessed and clarifies what strong responses include. Students learn the core components of a well-developed conclusion and how to link evidence, reasoning, and scientific understanding.
Subject-Specific Frameworks
Chemistry
Guidance on discussing reaction rates, enthalpy, equilibrium, and related theory. Includes an example investigation illustrating how to link results to chemical principles and literature values.
Biology
Support for writing about biological rates, enzyme activity, photosynthesis, and ecological relationships. Emphasises interpreting trends and connecting findings to biological concepts.
Physics
Frameworks for discussing motion, forces, energy, and waves. Students learn to compare results with accepted physical relationships or constants.
Step-by-Step Conclusion Builder
A structured three-part approach helps students organise their ideas:
Direct response to the research question
Justification using processed data and uncertainties
Connection to scientific context and accepted understanding
Additional guidance covers clarity, terminology, and use of evidence.
Quality Support
Checklists help students confirm that essential elements are included. A section on common issues highlights typical weaknesses and how to avoid them. Final review prompts support self-assessment before submission.
Ideal For
IB DP Science students writing their IA conclusion
Teachers supporting structured scientific writing
Students who struggle to link data and theory
Learners aiming for high-level performance
Classes focusing on improving conclusion quality
This guide removes uncertainty about how to write a strong conclusion by breaking the process into clear, manageable steps. Students learn to communicate findings precisely, use evidence effectively, and demonstrate sound scientific understanding.
Part of a broader IA support series, this worksheet is used after data analysis and before final report writing. Templates and examples help students see how strong conclusions are constructed within their discipline.
A practical tool for transforming brief summaries into well-reasoned scientific conclusions.
