Conditions of Use
We did an expirement. We had to swab different surfaces, we swabbed the gym door, the toilet seat, the toilet flusher and the gum under the table. We put it in a petri dish to grow the bacteria, here's what we found!
The gym door handle has the most bacteria out of the toilet seat, flusher, and gum under the table. The toilet seat had absolutely no colonies of bacteria growing on the agar. The toilet flusher had one large colony. The gum underneath our table grew three colonies of bacteria. The gym doors had over 20 colonies and two gigantic colonies. Most of the colonies were the size of a “.” some were the size of a “o” and the largest one was about twice the size of an “O”. One of our inaccuracies was contamination. In our gum under the table, there is bacteria growing away from where we swabbed, it was a contamination. In conclusion, if you go to Chimacum schools, I suggest that you was your hands after touching the doors.

I think you had a really good understanding of the bacteria lab. You spelled everything correct, I did not find anything wrong with it. You were descriptive in your observations. Good job!
