What is the IB Chemistry HL Internal Assessment (IA)?
The IA is an individual investigation that accounts for 20% of the final IB Chemistry grade. Students design, conduct, and report on a scientific experiment related to chemistry.
What are the assessment criteria for the Chemistry HL IA?
The IA is evaluated based on four criteria, each worth 6 marks, totaling 24 marks: Research Design, Data Analysis, Conclusion, and Evaluation. Each criterion contributes 25% to the IA score.
What does Criterion A: Research Design assess?
This criterion evaluates: Clarity of the research question, including defined variables and system description; Background information relevant to the research question; Justification of the methodology; Consideration of safety, ethical, and environmental issues.
What aspects are evaluated under Criterion B: Data Analysis?
This criterion focuses on: Recording and processing data clearly; Appropriate consideration of uncertainties; Accurate data processing relevant to the research question; Proper annotation of graphs, tables, and figures.
What is assessed in Criterion C: Conclusion?
This criterion examines: Relevance and consistency of the conclusion with data analysis; Justification of the conclusion based on results; Comparison to accepted scientific literature.
What does Criterion D: Evaluation entail?
This criterion assesses: Discussion of strengths and weaknesses; Explanation of the impact of methodological weaknesses; Suggestions for realistic improvements; Thorough evaluation considering control of variables.
What is the recommended structure and length for the Chemistry HL IA report?
The report should include: Title, IB candidate code, Word count, Introduction, Methodology, Data Analysis, Conclusion, Evaluation, References. Reports typically range from 1,500 to 2,500 words, with penalties for exceeding 3,000 words.
Why are safety, ethical, and environmental considerations important in the IA?
Addressing these considerations ensures: Safety by minimizing risks; Ethics by conducting research responsibly; Environmental Impact by reducing negative effects. Awareness reflects a comprehensive understanding of broader implications.
How does personal engagement influence the Chemistry HL IA?
While not a separate criterion, personal engagement is reflected in: Choosing a topic of interest; Demonstrating independent thinking and initiative. Engagement can enhance the quality and depth of the IA.
