Jeff wants to know what concentration of bleach would be most effective at killing bacteria without overdoing it and using too much bleach. Jeff makes 3 solutions of bleach in water, 1, 5, and 10% solutions. He then adds a specific number of bacteria to a test tube of each solution and waits 3 minutes. He puts these bacteria on a petri plate and later counts colonies to see how many bacteria survived.
In this experiment, the number of bacteria that were killed would be?
In this experiment, the concentration of the bleach would be?
Response/Dependent variable
Experimental/Independent variable
