Hello, my name is Christina Stathas and the purpose of my
science fair project is to determine which drink is best after a
hockey game.The reason that I chose this particular project
is because I wanted to learn more about the amount of
electrolytes we are putting into our bodies when we have
these drinks.

DEFINITION 2
My hypothesis was If Gatorade, Apple Juice, Orange Juice,
Chocolate Milk and Coca-Cola are me asured for the amount of
electrolytes, than Gatorade will have a lower conductivity because
sports drinks are made to replace ele ctrolytes lost, by sweating
when exercising.Here is some backg round information, An
Electrolyte is a scientific term for salt s, specifically ions. The word
electrolyte means that this ion is ele ctrically charged and moves to
either a negative or positive electrod e.

DEFINITION 3
When you exercise heavily, you lose electrolytes in your sweat,
particularly sodium and potassium. Th ese electrolytes must be
replaced to keep the electrolyte co ncentrations of your body fluid
constant. This is what electrolytes do for us.Electrolytes are
important because they are what y our cells use to maintain
voltages across their cell membrane and to carry electrical
impulses across themselves and to ot her cells.

DEFINITION 4
The outcome of the experiment hypothesis was correct,
Gatorade had the most electrolytes because it contained the
most sodium and potassium. This experiment followed a
specific procedure as follows:

DEFINITION 5
Finding the conductivity of each drink
Place the drinks in the refrigerator overnight.
Remove the drinks from the refrigerator and measure their
temperature.
Using a pipette, half-fill five wells of the spotting plate with
a different beverage.
