Chemistry IA Criteria and Checklist
If you’re an IB Chemistry student, you already know that your Internal Assessment (IA) is crucial to your final grade. But what does it take to write a high-scoring Chemistry IA in 2025? In this guide, we’ll break down the IB Chemistry IA criteria, provide a step-by-step checklist, and share tips to help you succeed! This guide provides a breakdown of the Chemistry IA criteria and a detailed checklist to help you stay on track.
What is Chemistry IA?
The Chemistry Internal Assessment (IA) is an independent investigation where you design and conduct an experiment, analyze data, and present your findings in a structured report. It counts for 20% of your final IB Chemistry grade, so doing well can significantly boost your overall score.
IB Chemistry IA Criteria and Checklist 2025
To score well, you must meet the following five IB Chemistry IA assessment criteria:
A. Personal Engagement (2 Marks)
- Shows originality and independent thinking.
- Connects the investigation to personal interest or real-world relevance.
- Demonstrates enthusiasm and curiosity.
- Tip: Choose a topic you’re genuinely interested in! It’ll make the research process more engaging.
B. Exploration (6 Marks)
- Clearly states the research question.
- Provides a well-defined hypothesis and scientific background.
- Uses appropriate methods and controls for a reliable experiment.
- Tip: Make sure your hypothesis is testable and backed by scientific reasoning.
C. Analysis (6 Marks)
- Presents data clearly with graphs, tables, and calculations.
- Provides a logical interpretation of results.
- Identifies trends, patterns, and sources of error.
- Tip: Use Excel or Google Sheets for data analysis to improve accuracy and presentation.
D. Evaluation (6 Marks)
- Discusses limitations and sources of error.
- Suggests improvements for future experiments.
- Justifies conclusions based on evidence.
- Tip: Be critical! Acknowledging weaknesses in your experiment can improve your evaluation score.
E. Communication (4 Marks)
- Uses clear, concise, and well-structured writing.
- Follows IB formatting guidelines (headings, citations, word count).
- Includes relevant diagrams, equations, and references.
- Tip: Keep your IA between 1,500 – 2,000 words and proofread to eliminate errors.
Chemistry IA Criteria and Checklist 2025
Before submitting your IA, go through this checklist to ensure you’ve covered everything:
Planning Stage
- Choose a clear and focused research question.
- Conduct background research to understand key concepts.
- Develop a hypothesis based on scientific principles.
- Outline a detailed experimental procedure.
- Identify and control variables effectively.
Experimentation Stage
- Gather all necessary materials and equipment.
- Follow the planned methodology and record observations carefully.
- Repeat trials to improve reliability.
- Document raw data, including uncertainties and units.
Data Analysis and Interpretation
- Organize data into tables and graphs for clarity.
- Perform calculations accurately and show all workings.
- Identify patterns, trends, and anomalies in the data.
- Compare findings with the hypothesis and scientific theories.
Conclusion and Evaluation
- Summarize key findings and answer the research question.
- Evaluate the accuracy, reliability, and limitations of the experiment.
- Suggest realistic improvements and potential extensions.
Final Report Preparation
- Structure the report with an introduction, methodology, results, conclusion, and references.
- Ensure clarity, coherence, and scientific accuracy.
- Cite all sources correctly using IB-approved citation styles.
- Proofread for grammatical errors and formatting consistency.
