The goal of this project was to determine, which of these 3 sports drinks (Vitamin Water, PowerAde, and Gatorade) supplied the most electrolytes versus chocolate milk. For this experiment I used a multi-meter that was used for measuring electrolytes in each drink. The control was distilled water. I performed three controlled tests on each solution. Unfortunately, I'm getting the same reading for ALL: 9.6
1) Cut two pieces of copper wire (6 inches long).
2) Use the princess frog (rubber) as the sensor.
3) Wrapped one piece of copper wire several times around the one of the leg (like you are winding a yo-yo). Leave about 2 inches unwound
4) Did step 3 again on the other side of the leg and ensured the two pieces of copper wire don't touch.
5) Connected the battery to the battery clip.
6) Took the positive end of the multi-meter and connect it to the positive terminal of the battery with an alligator clip.
7) Took one of the copper wires (sensor -princess frog and wrapped with copper wire), attach an alligator clip to it and the other end of the alligator clip and connected to the negative terminal of the battery.
Took the negative end of the multi-meter and connect it to the sensor (other princess frog) with an alligator clip.
9) The sensor (princess frog) was submersed in the drink sample and the results were recorded for each trial.
And as I stated, still getting a reading of all drinks of 9.6.
