How should IB Physics IA be written in 2025?
ANSWER: To improve your chances of receiving full marks on your internal assessment for IB Physics, adhere to the EXACT format of subheadings that I outline below.
Introduction
Research Question
Theory and Hypothesis
Variables
Diagram
Apparatus
Method
Raw Data
Processed Data
Graph
Analysis and Conclusion
Evaluation
References
1. Introduction
your introduction should come after your title. It ought to be succinct and direct. Many students think that describing your "passion" for your subject should be the main goal of the beginning. That is untrue. Please refrain from writing a ton of words here. Just provide a quick overview of the reasoning behind the topic selection.
Specifically which five sentences to use in your IB Physics IA.
2. QUESTION FOR RESEARCH
the distinct "Research Question" subtitle will help the examiner focus on the specifics of your inquiry and will also set the stage for its clarity. It's crucial that you take the time to make sure your research questions are precise, targeted, and will yield some useful findings!
Examples of hypotheses
a direct proportionality exists between the lasso's length and the square of its duration.
When the capacitor is discharged, the voltage across it will decrease exponentially.
It will also be helpful to include a drawing of an expected graph here.
4. Variables
You should clearly state your variables in this section:
The variable you are altering, Variable X, is an independent variable.
Variable Y is the dependent variable, which is the one that changes when the independent variable is altered.
Everything you must maintain constant to guarantee a fair test is known as a control variable.
Diagram
you ought to include a labeled schematic of your equipment. I advise you to make this diagram using Google Drawings; simply search for "Google Drawings" online.
The apparatus setup should be shown in a straightforward figure.
APPARATUS
this should be a list of the necessary equipment in bullet points. Here, don't get too specific. A short, straightforward list is acceptable.
7. METHOD
Once more, I advise you to keep this list to a minimum of ten bullet points, all numbered.
Add few points about safety and precautions
RAW DATA
Here, a data table will be included.
Only the data you gathered during the experiment (or simulation) should be included.
DO NOT include data processing (such as squaring, averaging, processing uncertainties, etc.).
Include the apparatus's reading inaccuracy.
Simply put a brief comment beneath the raw data table if you need to explain the apparatus's reading inaccuracy.
DATA PROCESSING
There will be a separate data table in this area. This is where you will display your processed data table. You might have to combine uncertainty and compute averages.
Don't forget to include the appropriate labels and units in each table column.
You should provide an example of any computations you have performed beneath the processed data table.
A GRAPH
graphing software, however, can be helpful in determining:
The data points' optimal line of fit
your two variables' mathematical relationship
the gradient's numerical value
the intercept's numerical value
the coefficient of correlation
