To grow bacteria on a petri dish, you will need several items.
First you will need a petri dish with lid. The petri dish must contain agar, which is the source of the nutrients for the bacteria you want to grow.
Then you will need sterile cotton tipped applicators. They must be sterile so that the bacteria you put in your dish is the only bacteria there, and not extra from an exposed cotton swab. There are also other laboratory tools that can be sterilized to pick up bacteria with.
Then you need your source of bacteria.
When you know what type of surface you will be swabbing, isolate one area, and swab it thoroughly with the cotton tipped applicator. Then, immediately swab it gently onto the agar surface with a back and forth motion.
If testing two different specimens with one petri dish, be sure to only swab half of each side with each specimen. On the bottom of the dish, use a marker to note which side contains which sample.
After preparing your petri dishes, place the lid on them and be sure they are labeled for easy identification. Then your specimens need to be incubated. Different types of bacteria thrive better at different levels of incubation and time. See a laboratory manual for incubation times.

What scientific instrument can grow bacteria and has a lid?
a petri dish
What is the container used for growing mold or bacteria called?
the containor used for growing mold and bacteria is the PETRI DISH. a lot of people use agar as the gel to grow mold and bacteria
Why would you grow bacteria in petri dishes?
put agar in a Petri dish, then use a Q-tip to wipe a dirty surface, then spread it on the Petri dish in a zigzag motion, then it will grow over time.
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.
What the most common way to grow bacteria is?
The most common way to grow bacteria is in an agar petri dish. The bacteria are usually placed by a swab into the petri dish and incubated for a predetermined period of time (The agar serves as a food source for the bacteria). Then, growth, or no growth, of bacteria will be observed.
A mass of bacteria growing in a petri dish?
Any bacteria with right nutrient in vitro can be cultured. This method is very useful when carrying out any experiment. As long as nutrient medium is maintained bacteria will grow with no problems in a petri dish.
What is the function of a pietri dish?
A petri dish is a flat dish made of either plastic or glass. It is used primarily to grow a culture of bacteria.
What is used to grow colonies of bacteria away from open air contaminants?
A Petri dish is commonly used to grow bacteria, because it is sealed and sterile.
What are the uses of petri dishes?
is a shallow cylindrical glass or plastic lidded dish that biologists use to culture cells - such as bacteria - or small mosses.
What is a dish used to grow microbes?
This is called a petri dish named after a German bacteriologist, Julius Petri.
What is a covered dish used to grow cells?
a petri dish
What laboratory apparatus will determine if a bacteria is alive or not?
One method is a petri dish because the bacteria would grow or not grow in a warm environment. Or a microscope because you could see any activity of the bacteria.
