Observations
Date
Observation
3/11/14
One Petri dish had a smaller inhibition zone from the rest. The
E. coli was smelly and white.
3/13/14
The Petri dishes had a lot of E. coli, the bacteria was white and extremely
smelly.
3/14/14
The E. coli on some of the Petri dishes were blotchy.
3/18/14
The E. coli was smellier than usual and filled up every Petri dish completely,
besides the zone of inhibition.

Recap
What we planned.
 What happened.
 Added Ampicillin to E. coli and incubated
the petri dishes.
 The bacteria and inhibition zones grew.
 Overtime, the inhibitions decreased in size.
 The hypothesis was accepted!


29
Improvements for the
Future
Run more trials.
 Have a wider range of the predictor
variables.
 Use of an actual human.
 Stop experimental flaws.

Goslow-Pushani
30
Flaw and Human Errors
Off temperatures.
 Off measurements of Ampicillin.
 Time issues.

Save Your Life
Do not take the antibiotics for viral infections.
 Take an antibiotic exactly as a healthcare
provider tell you.
 Keep antibiotics to a minimum.
