Hypothesis, Materials and Procedure
Statement of the Problem:
(Kumu Stenger’s experiment example)
Which sports drink is the most effective in replacing lost electrolytes?
Hypothesis:
(First identify your control, variable and results, then plug them into one of the two hypothesis formats
and adjust the sentence to be grammatically correct. Your hypothesis should be one sentence and
include your prediction on how the test will result.)
Control: Sports drinks (Gatorade)
Variable: The amount of electrolytes
Results: Effectively replacing electrolyte in the body
Based upon my research (or experience), I predict that ..(control)..(variable) .. will ..(result).
Based upon my research, I predict that the sports drink Gatorade has the highest amount of
electrolytes and will most effectively replace electrolytes in the body.
If…(control)..(variable)..then..(result)., therefore…
If the sports drink Gatorade has the highest amount of electrolytes then Gatorade will most effectively
replace the body with electrolytes, therefore consuming sports drinks with the highest amount of
electrolytes will be the most effective way to replace lost electrolytes.
Materials:
(List each item, in detail, bullets. Specify how much of each is needed.)




1 16oz. bottle of lemon-lime Gatorade
1 multimeter
2 alligator clamps
1 500ml beaker
Hypothesis, Materials and Procedure
Procedure:
(Make a thorough list of all the steps necessary to do your experiment. Also, include what data you will
be recording and how. The Procedure should include every detail that is needed to replicate your
experiment. Write it exactly as you are conducting your experiment. The number of steps depends on
each experiment.)

Wearing safety goggle and gloves use a wire cutter to cut two pieces of copper wire, each 15 cm long.
Using a small saw cut the plastic outer tube from a disposable ballpoint pen into a 2.5 cm piece.
To build a conductor, wrap one piece of the bare copper wire tightly around the tube 5 times. Note there will be
some wire left unwrapped, creating a “tail”.
Repeat step 3 with the other piece of wire on the other side of the tube.
Take the multimeter’s wires and connect the red wire to the positive terminal of the battery
Connect the black wire to the conductor. Use an alligator clip connector if needed.
Take a paper clip and connect the other conductor tail to the remaining battery terminal to close the circuit.
Take 10-250 ml beakers and fill 150 ml of each sports drink. Label each beaker before filling. Label them Gatorade,
Vitamin Water, All Sport, Mizone, Powerade, Staminade, Accelerade, SoBe Life Water, Propel, and Water. All
solutions should be room temperature.
Take another 250ml beaker and fill with water, for rinsing.
Turn the multimeter to read DCA (direct current.)
Set the meter to DCA 200 micro amps for water and set to DCA 200 milliamps for sports drinks.
Place conductor sensor in water, record the multimeter reading on data sheet.
Rinse the conductor sensor, and then test in sports drink. Record the milliamps reading on data sheet and rinse
conductor.
Repeat step 13 for each sports drink.
Clean all materials after use with warm soapy water.
