A student lab group is brainstorming the design of an experiment that uses a gas-filled balloon to determine how the temperature affects the volume of the gas. They come up with the following experimental design: "Inflate a balloon. Put it in a beaker of water. Measure the volume of the balloon and the temperature of the water. Inflate a different balloon. Put the balloon in the same beaker and measure volume and temperature. Repeat the procedure for a third balloon. Make sure that each balloon is inflated to a different volume each time you blow into it."

Explain why this is a poorly designed experimental setup. (Hint: Consider the independent and dependent variables.)
