Helping you with common stumbling blocks in Applied Physics
While physics classes cover theory, the IA demands practical application. The transition from solving textbook problems to managing real-world data entropy is where grades are often lost. That’s why we’re here to help you get over this new found difficulties:
«The error propagation is a mess.» In IB Physics, calculating the mean is not enough. You must propagate uncertainties through every calculation. We teach you to convert absolute uncertainty to percentage uncertainty during data processing.
«Choosing a topic that is ‘theoretically’ impossible.» If you cannot collect primary data or find a robust simulation, your investigation into modern physics will fail the «Exploration» criterion. Our tutors are prepared to guide you towards topics that are possible for you to study with the means you have at hand.
«My graph is a curve, and I don’t know why.» A core skill in the IA is linearization—manipulating variables (e.g., graphing $T^2$ against $L$) to produce a straight line. Many students leave their data as a curve, making it impossible to calculate physical constants like ‘g’ or ‘k’ from the gradient, which is a key requirement for high marks. Our teachers will help you analyze your variables correctly to obtain a straight line-
«Not distinguishing between systematic and random errors.» In the Evaluation section, simply saying «human error» is a grade-killer. We intruct you in identifying specific systematic errors (like a zero-offset on a voltmeter) versus random errors (like reaction time), so you can propose improvements to your methodology.
Deconstructing your IB Physics Investigation
To master this component (that’s equivalent to the 20% of your final grade), you need guidance from true experts. Our team comprises of people who once were students like you, but have become IB certified teachers, mechanical engineers, and physicists who understand the mathematical beauty required by the international baccalaureate curriculum. We know exactly how to structure an experiment and a 3,000 words report that meet the stringent demands of the internal assessment:
Personal Engagement (2 points)
Your investigation must show independent thinking. You can show this by building a custom rig or modifying a standard experiment to study a new variable.
Exploration (6 points)
Is the research question focused? Have you identified the Independent, Dependent, and Controlled variables? Are any safety concerns addressed?
Analysis (6 points)
This is the mathematical core of the assignment. Have you linearized your data? Do your graphs have error bars? Have you calculated the gradient and intercepts?
Evaluation (6 points
This measures your ability to compare your experimental value to the accepted scientific value and to analyze the percentage error.
Communication (4 points)
The report must be concise and correctly formatted. Any significant figures must be consistent throughout.
