Suds vs. Bacteria
Does the amount of
suds correlate with the
effectiveness of the
soap?

More Suds!!
Your hands are filthy. You turn on the
water and rub on soap. Immediately,
white suds start to form. Why are there
suds? Could they possibly help clean
your hands better? In that case, would
more suds mean your hands are
cleaner?
Hypothesis
We predicted that
if we tested the
effectiveness and
the amount of
suds from each
soap, then we
would find a
correlation
between the two
results.

Results (cont.)
Texture of suds differ in
antibacterial/hand and bio- soap
 Suds last longer in anti-bacterial and
hand soap
 Length of time that mixture is shaken
affects amount of suds

Conclusion



There appears to be a correlation between
the amount of suds and the cleanliness of
the soap.
The Bio-soap was the least efficient at
cleaning up bacteria.
The Anti-Bacterial soap was the most
efficient at cleaning up bacteria.
Assumption



The scent of the soap will not affect the
bacteria.
The force at which the soap-water solution
will be shaken will not have a significant
effect on the formation of the suds.
The more surface area (more suds) will pick
up more dirt.
Acknowledgements
We would like to thank our instructors for
providing the supplies and for supporting us
through out our lab.
We would like to thank Rachael for letting us
use her soap.
We would like to thank ourselves for doing
this lab.
