Which brand of band-aids stick the longest?
Which brand of band-aids stick to skin the longest?
Hypothesis:
If Top-Care is more expensive than All-Kids, then it will stick to skin the longest because it is a bigger brand name.
Steps to experiment:
Get two brands of band-aids: Top- Care and All Kids
Stick them on the same place on each arm
Check every 10 minutes to see if they are still sticking
Wait for one to come off, record how long it stuck
Wait for the other to fall off, record how long that one stuck
Observations
The Top- Care band-aid felt the most comfortable and had a stickier side.
The All Kids band-aid did not feel as comfortable or sticky.
Conclusion
The Top-Care band-aid stuck the longest with a total of 5 1/2 hours. The All Kids band-aids stuck for a total of 2 1/2 hours. This does support my hypothesis because I predicted that the Top-Care band aids would stick the longest. For more accurate results, I would retest this at least 2 more times. There was error in my results because I had 2 independent variables.
Variables:
Independent Variable: Brand of band- aids
Dependent Variable: How long the band-aids stick
Constants: where band-aids are placed, non-waterproof
Data
The Top- Care
band-aid stayed on for
5 1/2 hours
Data
The All Kids
band-aids stayed
on for 2 1/2 hours
