IB Physics IA Guide: 13 Things you need to know

IB Physics IA Guide: Everything you need to know

Internal Assessment (IA) is a crucial component of the International Baccalaureate (IB) program that frequently causes students anxiety. The IB is undoubtedly a demanding and dynamic program to begin with.

When done correctly, Integrated Assessment or IBDP Physics Past Paper can be a valuable tool for students, providing them with high grades. If you have the proper guidance, you can enter the exam hall with marks already in the bank.

With this IB Physics IA Guide, that’s exactly what you can expect! Students frequently complain about IA being a headache and for being a bit too tough.

Internal assessments can now take the form of a workbook, project, paper, oral exam, or series of experiments, depending on the subject matter. They are graded by an internal examiner and subsequently reviewed by an outside IB expert.

Thus, you shouldn’t be concerned if your teacher assigns marks that are excessively rigid because the moderator will ensure that you don’t suffer and that the marking is consistent across all IB schools.

You can comprehend the idea behind the IA and how to approach it by using this IB Physics IA guide.

How should IB Physics IA Guide be written?

1. Overview Of IB Physics IA Guide

Your introduction should come after your title. It ought to be concise and direct. Many students think that you will receive Personal Engagement marks (2/24) in the introduction when you describe your “passion” for your subject. That is untrue. Please refrain from writing an extended essay here. Please provide a brief overview of the reasoning behind the topic selection.

2. Question for research

The distinct “Research Question” subtitle will direct the examiner’s attention to the precise topic of your investigation and provide context for the investigation’s clarity. You must take the time to make sure your research questions are precise, targeted, and going to yield some helpful information! Also, the IBDP Physics IA Guide Mock Paper would be a perfect choice to make.

Generally speaking, the research question should look like this:

What effect does Variable X have on Variable Y?

3. Concept and Conjecture

The physics theory underlying your research question is covered in this section, which eventually enables you to develop a well-informed hypothesis about what is likely to happen with your findings.


This section doesn’t need to be very long. Giving far too much background physics on topics unrelated to the research question is the most significant error that most students make in this section.

This portion of your research can be very challenging. Obtaining the proper background and theory in physics is crucial because it will form the basis of your hypothesis, which will then form the basis of your evaluation and conclusion.

Example conjecture :

  • The square of the lasso’s duration will determine its length in a direct proportion.
  • When the capacitor discharges, the voltage across it will decrease exponentially.
    Here, a sketch of the anticipated graph will be helpful as well.

4. Variables

  • Indicate your variables clearly in this section:
  • Independent Variable: Variable X is the one you are modifying.
  • Dependent Variable: Variable Y is the variable that changes as a result of the independent variable changing.

Control Variables: whatever you must never change in order to guarantee an impartial test.

5. Diagram

Include a labeled diagram of your equipment with your submission. To create this diagram, I suggest using Google Drawings (search for “Google Drawings” on Google).

6. Apparatus

This equipment list ought to be presented in bullet points. Don’t get too specific in this instance. A brief and easy-to-read list will do in IB Physics IA Guide

7. Method

Once more, I advise you to have a short list of bullet points with numbers here—no more than ten!

Myth buster:

It is not necessary to include items such as “Set up the apparatus” and “Collect the sellotape.” Please assume that the reader is literate enough to understand the apparatus and the diagram and be able to set it up on their own!

8. Raw data

Here, you will include a data table.

  • DO limit your inclusion to the Information gathered for the experiment (or simulation).
  • DON’T involve any data processing (such as squaring, averaging, or handling uncertainties).
  • DO mention the device’s reading error.

9. Analyzed Information

There will be a different data table in this section. This is where you will see your processed data table. Averages, combining uncertainties, and additional data manipulation may be required.

10. Interpretation and Verdict

This is the point where you evaluate the accuracy of your data and draw conclusions from the data displayed in your graph.

Try to incorporate the following:

  • A brief summary of your theory
  • Explain the trend or pattern that is visible on the graph.
  • If the line of most excellent fit passes through the origin, what was your expectation?
  • Compare the trend displayed to your hypothesis; are they consistent?
  • You can gauge the accuracy and dependability of your results by looking at the gradient’s uncertainty.
  • If you want to know how reliable the results are, you can comment on how the points are distributed around the line of best fit.
  • Do any unusualities? On the graph, circle them and leave a comment.
  • Is it possible to determine a number using the gradient? (For example, mass, gravitational field strength, etc.)
  • Does the x or y axis have a constant intercept?

11. Graph

The computer does not need to process your graph. Draw the graph on graph paper if you are having trouble using the specific software.

Graphing software, however, can be helpful in determining:

  • The data points’ optimal line of fit
  • The connection between your two variables mathematically
  • The gradient’s numerical value

12. Assessment

The majority of students lose interest at this point.

Myth buster:

Writing “carry out more trials” or “use a more accurate ruler” is not enough. These errors are not sophisticated enough!
