Science Buddies: "Ask an Expert"

For my project I am seeing how much bacteria multiplies depending on the amount of time it is left in the open air. However, I need to incubate the bacteria, but I have no idea how to. I have heard you can use your oven, but i am not sure how accurate that is. Please keep in mind that I DO NOT have access to a high end lab. All input is appreciated.
Thank you for your time ,

Hi Tonksie,

An oven with the light on is usually about 32 degrees C, but I don't recommend this because someone will invariable turn the oven on without looking and destroy your science project. Try testing the temperature at the top of the hot water heater, or put a light pump in a box. Try to find a place that is 25 to 35 degrees Centigrade. Over 40 degrees C is definitely too hot. If you don't have a warm place to use, you can incubate at ambient temperature. The bacteria will grow a little more slowly, but they will eventually grow.

What are you doing for your project?

Hi
The speed of multiplication of different bacteria differs between species. E.g. bacteria which live in body have higher speed in 37 C degree or we have archi bacteria which are termophilos (they live in very hot places like volcano) . first of all you should clarify which bacteria you are using.
