The pour plate method involves adding melted agar to a small amount of inoculum before pouring the mixture into a Petri dish. This allows the bacteria to grow throughout the depth of the agar, resulting in colonies both on the surface and down throughout the agar. The streak plate and spread plate methods typically only result in colonies on the surface of the agar.
