Bacteria Breath

CSEF · 2003 Microbiology

Jessica L. Tune · Twain Harte Elementary, Twain Harte

Overview

Objectives/Goals My objective was to learn who had the most bacteria, cats or dogs. Methods/Materials I contacted and collected dog and cat samples from T.H. Veterinary. Gathered materials needed. I watched and recorded results for 7 days. Needing a more scientific approach for measurement, I redid the experiment. This time, measuring(using graph paper)graphing and taking pictures daily. After 7 days I recorded the results. Results The dogs had 8% more bacteria than cats, after one week of testing. Conclusions/Discussion Even though dogs had 8% more bacteria than cats, one individual cat had the most bacteria out of all the animals, but the dogs as a whole had more bacteria. I tested 6 dogs and 6 cats to make my results more exact and both times dogs had more bacteria.

Summary statement

My project is an experiment of the comparison of bacteria in cats and dogs mouths.
