Weigh a metal block in air, in water and in salt solution to find the upthrust and the density of the metal.
Time a pendulum at several lengths, plot T² against length and find g from the slope.
Load a spring step by step, measure its extension and find the spring constant.
Pull a loaded block along a bench at steady speed and find how friction depends on load, surface and area.
Vary the current through a resistor, record current and voltage, and find its resistance from the V–I graph.
Measure two resistors separately, then joined in series and in parallel, and compare with the formulas.
Trace a ray through a rectangular glass slab at several angles and verify Snell’s law.
Focus the image of an object on a screen for several object distances and find the focal length.
Drop a hot metal block into cool water, measure the final temperature and work out the specific heat capacity of the metal.
