If you're looking for something genuinely serious that is even remotely interesting you could calculate the radioactivity of common food stuffs and see how that affects our yearly absorbed dose of radiation. That's a good one if you plan to do medicine, but you'll need things like Geiger Müller Tubes and whatnot. You would also have to take into account background radiation. That's one idea anyways and it's not too hard, but it isn't really that quick an experiment and it will probably takes a good month or so.

I like the Atwood's machine, but hardly simple!
Investigate how the time period of a pendulum varies with the amplitude. Pretty simple.
How much load a single eggshell can support. Simple but messy.
'Creep' in plastic when it is stressed. Simple in one sense, but tricky to do well.
Current/voltage characteristics of a light bulb. Very simple, but with depth if you want to take it further,

Gravity and 1 chair
demonstrate a simulator
place a person in the chair with their eyes closed and tilt the chair 15º to 30º
sin15º = .2588 * 32.17 = 8 ft/s² - very slow take off
sin30º = 0.5 * 32.17 =16 ft/s² - very fast take off
A DC - 9 accelerating down a runway !
