In 2020, I received 45 points in IB, including a 7 in HL Physics. This IA allowed me to achieve that grade. Understanding its style, structure and presentation can help boost IAs mark considerably.
The essay’s title is, ‘The Impact of Salinity on the Surface Tension of Water’, and scored in the highest grade boundary.
This essay is to be used as an exemplar ONLY, to show an example of what a high-scoring IA looks like. Academic honesty is extremely important in the IB, and any plagiarism will risk the whole qualification.
