Is there a simple way to measure atomic weight? of what? I'm looking for something that a youngster could reasonably attempt.

For many of the more commonly available elements you can utilise either
the fact that 1 mole of a gas occupies 22.4 litres at n.t.p. (293.3 K,
760 mm Hg), or you can use electrolysis by measuring the amount of
an element deposited during a known time by a known electrical current.
