My investigation was to test different drinks to see which one was best at replacing electrolytes lost through sweat. My problem was to see which type of sports drink was best. My second problem was out of water, milk, orange juice, Gatorade, Powerade, and Body Armor which is the best at replenishing electrolytes.

My hypothesis was that Powerade would be the best since it was newer and therefore had more advances in science and that milk would be the worst because of its high amount of cream.

Materials
To begin this experiment, I bought orange juice, Powerade, Gatorade, and Body Armor. I made sure to get all the sports drinks in grape flavor to get them as similar as possible.
I then bought two packs of alligator clips to set up the circuit. I used one set of alligator clips to connect a 9-volt battery to the multimeter and the other set I connected the multimeter to copper wires. I used pliers to bend the ends of the copper wires into a circle.

I then slid five inches of a plastic straw into the circles. I used a different straw for each drink. The straws were placed into a glass bowl filed with the drink. I washed out the bowls between tests with soap and warm water. While doing my testing, the orange juice corroded my copper wires. I replaced the copper wire and continued the experiment.

Procedure
I took the readings in volts and then amps. I then had to plug them into a formula to determine the electrolyte reading.
• The water read 3.7 micro-amps (µA) and 1 micro volts (µV), equaling 37.5 Siemens (S).
• The orange juice read 3.98 µA and 1 µV, equaling 3.98 S.
• The milk read -4.05 µA and 1 µV, equaling -4.05 S. Since it is impossible to have a negative electrolyte reading, it is just zero.
• The Powerade reading was 38.5 µA and 8.5 µV, equaling 4.53 S.
