Problem

What sports drink has the most electrolytes to replenish you for sports?

Hypothesis

I think that gatorade has the most electrolytes because I’ve seen NFL players drink it and then run for miles.

Procedure

Making a Conductance Sensor

    1. Cut 2, 5 cm, (2 inch) pieces from a large drinking straw.

    2. Cut two pieces of copper wire, each about 12 cm (5 inches) long.

    3. Wrap the two pieces of wire around each end of the straw, leaving 5 cm of wire.

    • Make sure you wrap the wires snugly around the straw so they do not slide back and forth.

    • Make sure the two wires do not touch. The conductance sensor will not work if the wires touch, and touching wires will blow the fuse in your multi-meter.

Making a Measuring Circuit

    1. Connect the multimeter probes.

      1. Make sure your multimeter's center dial is in the "OFF" position.

      2. Plug the black probe into the port labeled "COM".

      3. Plug the red probe into the port labeled "VΩMA".

      4. Connect the red alligator clip to the red probe and the other side to the battery snap connector.

      5. Connect the black probe to the black alligator and connect the other side of the black alligator clip to the conductance sensor.

      6. Connect the green alligator clip to the other piece of copper wire on the conductance sensor and the connect the other side to the other wire of the battery snap connector.

Begin the Experiment

    1. Label the bowls with the liquid inside of them.

    2. Pour the liquids into the bowls.

    3. Put all the bowls on the scale and make them the same weight.

    4. Plug in the Explorer GLX, and make sure all the liquids are the same temperature for a fair test.

    5. Turn the multimeter to 200m (milliamps) and begin testing. (Make sure the conductance sensor is fully submerged for a fair test.

Converting to conductance:

    1. Note that conductance is the inverse of resistance, which is measured in ohms . The symbol for resistance is R, so G = 1/R (resistance) (1 S (Simen)= 1 / ohm). Another way to think about it is Ohm’s law, which uses resistance instead of conductance: V = IR.

    2. Convert Milliamps to to thousandths of an amp; or Microamps, millionths of an amp.

    3. Before you start Ohm’s law, you must convert your microamps to amps.

    4. The voltage is 9V, because we used a 9V battery, and amps would be your current, so divide amps by voltage and that will equal you conductance in siemens.

  1. For my graphs, I didn’t want a long number so I converted my siemens to millisiemens. To do so, I removed the first 3 decimal places and that will equal a milli siemen.

Abstract

Which drink has the most electrolytes to replenish you for sports?

(Gatorade, Orange Juice, Fiji water, or tap water)

I was looking over and over again for science fair ideas that had to do with technology and chemistry, until I found the one website that had a great idea. I borrowed the idea. I thought that Gatorade would have the most electrolytes because NFL players drink Gatorade, and then run for miles.

I started out my experiment with making a simple conductance sensor which consisted of a piece of a straw and two pieces of copper wire. Then, I put all the liquids into a bowl and onto a scale so they would all be the same weight which was around 1one pound. I also made the temperature the same and the temperature i set on was 19.4 degrees celsius.After that, I made a conductance measuring circuit with a digital multimeter. In order to measure my conductance I had the set the multimeter to “200μ.” Once I finished measuring and recording my data, I started to convert the M’s to Amps (amperes.) Then I used a equation from Ohm’s law to convert the Amps to conductance. The equation was conductance measured in siemens was equal to the current in amps over voltage. I already knew that the voltage was 9V because I used a 9V battery. Then I just got my answer in conductance and calculated an average.

These are my averages. Orange juice had an average of 0.02272222. The average for Gatorade was 0.01824444. The tap water was 0.00186667 and the Fiji water was 0.00208889.All these measurements were converted to siemens.

In conclusion, I learned that orange juice has the most conductance which means orange juice had the most electrolytes. My hypothesis was correct. While playing sports having more electrolytes can mean a lot more to you. A possible follow up experiment could be to include other drinks like powerade or red bull to see if you can find more electrolytes.

Conclusion

In conclusion, Orange juice has the most electrolytes. My hypothesis wasn’t correct. Orange juice had an average of 4.5 milli siemens. Gatorade had 3.5, tap water had 0.2 and Fiji water had 0.4.
