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.
