in my test a piece of ph paper is placed in shampoo and the ph level is recorded. What is the in dependant variable and the controlled variables in this test?What is the independent and controlled variable in this test?????
The independent variable is the pH of the shampoo, and the controlled variables are the amount of shampoo, the temperature of the shampoo, the sterility of the pH paper, the time the pH paper was left in the shampoo... I can't think of anything else.What is the independent and controlled variable in this test?????

i think the independent is the shampoo because it doesn't change any part of itself ..and the ph paper is the controlled variable or dependent because it changes when it reacted ..
