100mL of each drink into beakers massed them placed the drinks in the oven find difference in mass Unfortunately, at the very end of my experiment all of the colored drinks turned to a syrup and couldn’t be measured.
I remembered electrolytes increase conductivity. So I ran a current through 40mL. of each drink and measured the current and voltage, then divided to find the resistance. My Experiment.
V=I R Voltage=Current x Resistance To get the resistance I then divided the voltage by the current. The less the resistance the more hypertonic it is.
Same size beakers. Same amount of drink (40mL.) All room temperature. Same power supply, meters. Same brand/size of beakers. Basically same ingredients. Same wires in same meters
To make sure no other factors were influencing my experiment water was my control group.
Wash and dry all beakers and graduated cylinder.
Use graduated cylinder to fill 20 beakers with 40mL of each drink. 5 beakers per drink.
Test each group of drinks one at a time till all 20 beakers are tested. Repeat experiment with water. (control group.)
V (volts) I (current) r (resistance) average
Due to standard deviation my results are in conclusive. I found that my data does not support my hypothesis. Therefore I reject my hypothesis that Gatorade is more hypertonic then other leading sports drinks.
I had a few outliers in my data, and I believe they are from the wires I used. After a few uses they began to turn black and got a coating on them. I tried my best to clean them off with a magic clean eraser but the coating may have effected my results.
I did some research after my experiment and found out that Propel has actually added a new ingredient that the other drinks have much less of. Propel contains a higher concentration of sucralose which might be the reason that Propel differed from the other drinks by such a big margin. Improvements and research:
I had to restart my project multiple times and I had a few trial and errors but over all I think my experiment went well. If I had to repeat my project I would make sure all the drinks were the same color and I would include more trials with more leading brand drinks.
