Dependant Variable is what changes will hapen itself for example what changes will happen in a reaction.
Independent Variable is what you will change. So if you were for example to add more hydrochloric acid in a soulution, you will be changing the concentration of it (different amounts of it), to see what will happen.
Controlled Variable is what you will have to keep the same inorder for it be a fair teat.
