What will be kept the same (control) in the test?

The control variable is the one that is kept same in the test an throughout the test

Explanation:

The scientific constant that is kept constant throughout the experiment is not changed and the value remains constant throughout the experiment and they have strong influence in the results

To test the relationship between the dependent and the independent variables determination of the control variable is necessary and the resulting value changes if the control variables are not kept constant throughout the experiment

This will also bring about the co relationship between dependent variable and the independent variable

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.
