Is there an explanation of why bacteria from one different swabbed object will grow more colonies on a petri dish than another?
It could be the medium in the Petri dish in which the different bacteria grow. It could also be the swabbing technique.
Why should a petri dish not be left open for any extended period?
Other bacteria and germs could contaminate the contents in the dish. The dish is meant to isolate a subject in an experiment so one can study it. While in the dish, one can control the reactions by putting in what they want in the dish. If the dish is left open, then one will be studying the contaminates and will not get accurate results from their experiment.

Is a thermometer a thermal insulator?
It depends on the material out of which the dish is made. Materials are considered conductive if they transfer heat faster than the surrounding medium and insulators of the transfer heat slower than the surrounding medium. If the medium is air, a glass dish will be a thermal insulator but a metal dish will be a thermal conductor.The rate at which heat flows through a material is related to its thermal conductivity.
