On 19 and 20 June, the Grade 11 Physicists spent two days off-timetable working on their Internal Assessment (IA) projects for their IB Physics course. These projects contribute 20% of their final grade.
Subjects for research this year were diverse, including determining the clay content of pencil lead using resistivity measurements, the relationship between temperature and the speed of sound, the effect of temperature on the viscosity of engine oil, measuring the ground effect on a wing, measuring the Magnus effect (which allows a football player to curve a ball in flight), the relationship between the tension of a plucked string and the note played, the acceleration of different model cars on a ramp, the effect of blade pitch on the effectiveness of a propeller, and the effect of internal pressure on the bounce of a basketball.
