It's not for a beginner, but this generic electret microphone capsule is just made for an intermediate science project. The capsule, which probably came from a cell phone or similar device, is nominally rated at 2.2K ohms. It's 7/32" thick x 3/8" dia, with (2) 1 1/2" leads terminating in a polarized 2-pin connector. Circuitry diagrams are available online at several sites.

Or sort-of-locking. Push the plunger down and they lock in place, but push the 1/8" nipple down on a hard surface and they'll unlock for re-use. Handy in the shop or craft room for oil, grease, paints, and glues. (Also quite useful for getting liquid medication into the dog.) They measure 3-1/2" long x 9/16" dia and hold 5ml, are graduated in .2ml increments, and have threaded tops. Note the throwaway price.
