Leo placed two Circles of paper and a petri dish (something used for bacteria) one Circle of paper was soaked in penicillin the other had nothing on it. He poured a liquid filled with bacteria into the Petri dish both Circles of paper were placed in The Petri dish about 3 cm apart at the end of the experiment a circle with a radius of 2 centimeters formed around the circle of paper soaked in penicillin there where no bacteria growing in the two centimeter Circle nothing had occurred around the other circle of paper the Victoria were going well.

a. what was the Dependant variable?

b. what was the Dependant variable?

c. what was the control group?

In this experiment, Victoria was testing the amount of bacterial growth with and without the presence of penicillin. Hence the variables:

A. The independent variable was the petri dish and circles of paper with bacteria soaked with Penicillin.

B. The dependent variable was the amount of bacterial growth.

C. The control group was the circle/dish with no Penicillin.
