Electrolytes in Orange Juice vs. Gatorade Sara Sheridan 9th Grade
Problem • What drink has more electrolytes and is consequently better for the human body-orange juice or Gatorade? • Rationale
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?
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.
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)
Procedure • Measure materials • Set up simple conductor • Test liquids • Repeat 5 times for each liquid • Record data
Variables • Independent Variable-Liquids • Dependent Variable-DCV measurement • Control Groups-Distilled and Tap Water
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
