agar plate experiment? (1 Viewer)
- Thread starter -pkaur-

did you do food or water, or both?
basically get an agar plate, and place a few drops of water (creekwater, distilled water, etc) or slightly rub food samples (nut, bread, apple) on the jelly. Put a lid on, tape it up so that nothing else gets in. Incubate it. Then after a few days examine the microbes that grew on it - size, colour, number, etc.
We split it into bacteria and fungi which can be easily distiguished.

Oohh. thank god for this thread. Just got this assessment today!! 
Basically, we get to choose either food OR water.
I'm choosing water---i have no idea why.. We were given two agar plates and don't have to use one of them as a control. The control plate is in our lab. So i was thinking of using pond water from school ( D: ) and then either bottled water/tap water or boiled water. But i reckon that the boiled water works better as a control.. D:
Help and suggests?
