III.1 LABS |
1.1 Structured activity sessions:
- Experimental data processing (approximate quantities, measurement of physical magnitudes, error estimation)
- Adequate operation with basic measurement instruments (flex-meter, micrometer, multimeter (analog and digital), oscilloscope)
- Laboratory experiments with mechanical or electromagnetic waves (emission and reception of ultrasonic waves, microwaves or light waves, standing waves along one direction, Michelson interferometer)
|
III.2 LABS |
2.1. Unstructured activity (open lab) sessions:
- A practical problem, formulated with basic initial data, will be assigned to each working team. Then, under the teacher’s supervision, each team must analyze the problem, select a possible solution and carry it out at the lab
- For the open lab problems, diversity of topics and experimental techniques are considered within the field of wave and electromagnetic phenomena, in particular, electric current conduction and electromagnetic induction in quasistatic regime
- As a reference, some open lab problems that can be proposed are: measuring the electric field on a weakly conducting sheet, numerical solution of the Laplace equation, measuring the self-inductance of a coil or a solenoid, measuring the mutual inductance of two coils or two solenoids
- As an option, the open lab sessions may be replaced by a well-documented piece of work reporting some topic/technique/process/device related to science or technology where wave or electromagnetic phenomena play an essential role. The report must include a model of the problem, clearly identifying the relevant quantities and physical laws
