Lyn Angela Escalderon bacteria growth

I put the bacteria plate in my living room for about 15 min three times a week at the beginning of September 22, 2015. For the past few days I put the bacteria plate in normal room temperature ( 23-25 Celsius Degree ).

Bacteria [Graph]: Types of Colonies per days 
If picture not shown: click image (1).
Conclusion:
    My bacteria plate is expose for 15 min in the living room for 15 days. I expose the bacteria in the living room around 5 or 7:00 p.m. The bacteria colonies started to grow rapidly over 100 colonies when it reach day 3. This is rapid growth, when the population does not decrease,but increase. The Bacteria plate increased rapidly of day 3, but slowed down on day 11-15.

What I learned:
    What I learned in this project that I get to observed the manifested bacteria with my own eyes. I've never seen the form of bacteria except on pictures. Even though a bacteria's form is small, it show a formation of the bacteria. The longer the bacteria is revealed to the atmosphere the larger the bacteria will become.
