Conclusion
In conclusion, #1 Tongue has the most bacteria. The bacteria spreaded really quickly. It was a very different type of bacteria from the other dishes. So, according to my observations, my hypothesis is correct.
The tongue has the most bacteria because it is in the mouth, where it is hot and humid. Bacteria grows a lot in hot, humid places. There is also the bacteria from your teeth, plaque, and the bacteria from the food you eat.
