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?
