Sometimes bacteria in a liquid are introduced using a sterile pipette to the Petri dish before the (fairly cool) agar medium is poured on top ("pour plates"). Then the Petri dishes containing agar or tubes containing broth are incubated, i.e. put in a special apparatus at a fixed temperature (usually 37°C - human body temperature, for possible pathogens - or 25°C for bacteria from the environment).
