Three different brands of tissues of same size were dropped in 5ml of water. I do not understand what's the experimental control and experimental variable. Is the experimental control and control group the same thing?|||It would help if you could tell us what the experiment is. It looks like the variable is the tissue, as there are three kinds which might behave differently in the one constant medium which is water.
Therefore, water is the experimental control, and tissues are the variable.
"While all experiments have an experimental group, not all experiments require a control group. Controls are extremely useful where the experimental conditions are complex and difficult to isolate. Experiments that use control groups are called controlled experiments."
I'd just like to add that your pug picture drew me to answer this question. I love pugs n have a male 3yr old of my own :)
