Science - Which is the controlled variable?

The Experiment:





Punching holes in Nappy Sacks then adding a hook with weights, you add more weights to see how strong the Nappy Sack is.





You then change the brand of the Nappy Sack eg. Tesco Value. And repeat.





You are trying to find out which brand is the strongest ?





What variables are these and why ?





Many Thanks !
