Overview

The IB Chemistry Internal Assessment (IA) is a lab-based investigation that requires students to design and conduct an experiment to answer a scientific question. The investigation should demonstrate a clear understanding of the subject matter and showcase the student's ability to think critically and analytically. This component of the IB Chemistry course is designed to assess a student's ability to apply scientific concepts and principles to a real-world problem.

Step-by-Step Guide to Planning Your IB Chemistry IA

To ensure a well-planned and well-executed investigation, students should follow these steps:

  1. Choose a topic: Select a topic that interests you and is relevant to the IB Chemistry syllabus.
  2. Conduct background research: Research the topic to gain a deeper understanding of the subject matter and identify potential research questions.
  3. Develop a hypothesis: Based on your research, develop a hypothesis that addresses the research question.
  4. Design an experiment: Design an experiment that tests your hypothesis and allows you to collect data.
  5. Plan data collection and analysis: Plan how you will collect and analyze your data.
  6. Prepare a detailed plan: Write a detailed plan outlining the experiment, data collection, and analysis.
  7. Conduct the experiment: Conduct the experiment and collect data.
  8. Analyze and interpret the data: Analyze and interpret the data to draw conclusions.
  9. Write up the report: Write a clear and concise report that summarizes the investigation, including the research question, hypothesis, experiment, data collection and analysis, and conclusions.

Common Mistakes to Avoid

When planning and conducting an IB Chemistry IA, there are several common mistakes that students should avoid, including:

  • Not conducting sufficient background research.
  • Not developing a clear and testable hypothesis.
  • Not designing an experiment that accurately tests the hypothesis.
  • Not collecting and analyzing sufficient data.
  • Not writing a clear and concise report.

Summary

Planning an IB Chemistry IA requires careful consideration and attention to detail. By following the steps outlined above and avoiding common mistakes, you can ensure that your investigation is well-planned and well-executed. This will help you to produce a high-quality report that demonstrates your understanding of the subject matter and your ability to think critically and analytically.

How iBacalao Helps

iBacalao is an AI study assistant built for International Baccalaureate students. It gives rubric-aligned feedback on Internal Assessments, reflections, Extended Essay drafts, and TOK work. Students can paste a draft into iBacalao and receive structured feedback on criteria, clarity, and common mistakes — without having the work written for them. You can use iBacalao to submit your draft and receive feedback on areas such as research question, hypothesis, experiment design, data collection and analysis, and report writing. This feedback can help you refine your investigation and ensure that you are meeting the IB Chemistry IA requirements. iBacalao is available at https://www.ibacalao.com.
