The one part may be a thermistor (heat dependent resistor), but if not I don’t know what it is.

Yeah, it’s a thermistor.

Wire it between an analog input and ground, set that input to INPUT_PULLUP on a sketch to display the analog value each second, see how it changes as you hold it in your fingers or put an ice cube on it.
