Electrolytes in Orange Juice vs. Gatorade

• Sara Sheridan
• 9th Grade

2
Problem

• What drink has more electrolytes and is
  consequently better for the human body-orange
  juice or Gatorade?
• Rationale

3
Research

• Electrolyte-any substance containing free ions
  that make the substance electrically conductive
• Main electrolytes in body
• Ingredients in Gatorade and Orange Juice
• Why are they important?

4
Hypothesis

• If orange juice and Gatorade are tested for
  electrolyte content, then Gatorade will exhibit a
  higher amount of electrolytes and is therefore
  more beneficial to the human body.

5
Materials

• Orange Juice (100 mL)
• Gatorade (100 mL)
• Distilled Water (100 mL)
• Tap Water (100 mL)
• Multimeter (1)
• Copper wires (2, 15.25 cm each)
• 9 Volt battery (1)
• Graduated cylinder, ruler
• Containers (4)

6
Procedure

• Measure materials
• Set up simple conductor
• Test liquids
• Repeat 5 times for each liquid
• Record data

7
Variables

• Independent Variable-Liquids
• Dependent Variable-DCV measurement
• Control Groups-Distilled and Tap Water

Data, ctd.

Conclusion

• The original hypothesis stated that Gatorade
  would contain the most electrolytes, as opposed
  to orange juice. The hypothesis was
  supported-Gatorade had the highest DCV
  measurement and therefore the most electrolytes.

Further Experimentation

• Problems with the experiment
• More in depth research before hand
• Brands of orange juice
• Different flavors/varieties of Gatorade
• Calculating the actual electrolyte count
