What is Julius Richard Petri known for?
Julius Richard Petri is known for being the inventor of the petri dish. In early bacteria studies, cultures were kept in lidless dishes and as a result they often became contaminated. Julius Richard Petri invented a dish with a lid that reduced the risk of contamination and this has become known as the petri dish.
Does a petri dish melt if microwaved for 3 minutes?
Petri dishes are generally made out of glass, so they will not melt if microwaved. If it is made of plastic, it may melt - but I would not expect it to.
Use of petri dishes?
A petri dish is a type of glass or plastic shallow round dish with a close fitting lid which is a vital tool in scientific laboratories. The uses for the petri dish are varied, but it is most well known for holding a culture medium upon which cells, bacteria, and viruses can be grown and studied. Most major scientific breakthroughs have been greatly assisted by the use of petri dishes whether they involve the structure of a virus or the ability to clone meat. The invention is named for Julius Richard Petri, who conceived of the idea in 1877, frustrated with existing tools for cultures. Most scientists used shallow bowls or bottles, which were awkward to work with and subject to contamination. Petri thought that a shallow circular dish would be easier to work with, and easy to make a lid for. The lid keeps the petri dish from being contaminated, and the basic shape makes them easy to stack and arrange in varied configurations. When a petri dish is used to culture cells, it is usually filled with a growth medium made from agar, a gel made with extracts from red algae, and a variety of nutrients. The growth medium has a gelatinous texture which most cultures thrive on, although sometimes the nutrients need to be varied to meet the needs of the organism being cultured. To satisfy the needs of finicky organisms, a scientist may take several weeks to adjust the environment of a series of petri dishes. Once the culture starts to thrive, the organism can be researched. There are other uses for the petri dish: many schools, for example, use them to teach students about seed germination, as the clear dish allows the observer to see every step of growth. In addition, the petri dish is commonly used for dissection, because it is ideally sized to be placed under a microscope. A petri dish can also be used for basic experimental purposes like transporting liquids in sterile containers or drying fluids for study. Other uses for the petri dish are constantly being explored by the scientific community, and it is a laboratory tool that is unlikely to be abandoned in the near future. Major advancements in science such as growing cells integrated with electronic circuits, cloning organs, and understanding viruses have been accomplished with the aid of the humble petri dish. Although other methods of studying organisms in the laboratory are being developed, the need for the basic ability to culture organisms rapidly in a sterile environment will never fade.
Tools used in science?
Some tools that are used in science include microscopes, tweezers, telescopes, computers, maps, and Petri dishes. Other tools include magnifying glasses, chemicals, and even Bunsen burners.

Can you incubate petri dishes at room temperature?
no
If you use petri dishes for blood do you have to use nutrient agar powder too?
if you use petri dishes do you put nutrient agar in it if your using blood?
Why should you label the petri dishes correctly?
The importance of labeling petri dishes is important. When looking at reaction on specimens or the growth of bacteria of items in a petri dish, if it is labeled incorrectly the data will be wrong and projects could be jeopardized.
How do you handle Petri dishes?
You have to put the liquids with a pipette, and then you can analyze it.
What equipment can be used to grow bacteria?
Agar and petri dishes.
What does a petri dish look like?
A petri dish is a round, shallow glass container with a glass lid. See the link below for pictures of petri dishes.
How should petri dishes be labeled?

Why are petri dishes incubated at 25 degrees in schools?
it is the same temperature as a body
What is a petri?
A Petri dish is a shallow glass or plastic cylindrical lidded dish that biologists use to culture cells. It was named after German bacteriologist Julius Richard Petri, who invented it when working as an assistant to Robert Koch. Glass Petri dishes can be re-used by sterilization (for example, dry heating in a hot air oven at 160 °C for one hour); plastic Petri dishes must be disposed of after one use.
