Science Fair: Finding the Best Electrolyte Drink after Hockey Game, Quizzes of Materials science

In this science fair project, christina stathas investigates which drink contains the most electrolytes to replenish those lost during physical activity. The project includes hypotheses, background information on electrolytes, experiment procedure, and results for the conductivity and ph levels of gatorade, apple juice, orange juice, chocolate milk, and coca-cola.

What you will learn

  • What improvements could be made to Christina Stathas' science fair project?
  • What drink has the highest electrolyte content according to Christina Stathas' science fair project?
  • Why is it important to replenish electrolytes after exercising?

DEFINITION 1
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.
TERM 2

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:

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.

DEFINITION 1

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.

TERM 2

DEFINITION 2 My hypothesis was If Gatorade, Apple Juice, Orange Juice, Chocolate Milk and Coca-Cola are measured for the amount of electrolytes, than Gatorade will have a lower conductivity because sports drinks are made to replace electrolytes lost, by sweating when exercising.Here is some background information, An Electrolyte is a scientific term for salts, specifically ions. The word electrolyte means that this ion is electrically charged and moves to either a negative or positive electrode. TERM 3

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:

TERM 5

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.

TERM 6

DEFINITION 6

  1. Place the electrodes in each drink, read and record the level of conductivity. 5.Wipe the electrodes with Kim-wipes between each test. 6. Repeat steps, # 4+5 times in the Measuring the conductance section two more times to obtain a total of three measurements for each liquid. 7. Average your results across the measurements for each liquid TERM 7

DEFINITION 7 Measuring the pH of each drink Half-fill 5 more wells of the spotting plate with a different drink. Get universal indicator paper Tear off a 2-3 cm piece and dip it in a drink Compare the colour of the paper with the legend provided Record the pH Repeat steps 3-5 times for all 5 drinks TERM 8

DEFINITION 8

After following all of the steps in the procedure, the results

that I found were for every drink was really close. My final

result wasGatorade with an average conductivity of 3 out of

8, Orange Juice was 2 out of 8, followed by apple juice with 2

out of 8, then Coca-Cola with 2 out of 8 and finally Chocolate

Milk with 2 out of 8.

TERM 9

DEFINITION 9 I performed 3 trials and got the same results each time. The results for the pH for Orange Juice was 4, Apple Juice 3, Orange Juice 4, Coke 2.5 and Gatorade was 5.From the results, I came to the conclusion that Gatorade had the most electrolytes because it contained the most sodium and potassium. If I had to perform my experiment again, I would have probably tried different drinks like for example homemade fruit shakes so I can see if it would have had a greater amount of electrolytes or less. TERM 10

DEFINITION 10

If I had to perform my experiment again, I would have

probably tried different drinks like for example homemade

fruit shakes soI can see if it would have had a greater

amount of electrolytes or less. I would have used an actual

conductivity meter and pH meter that would have provided

more accurate and precise results.
