We’ve got bacteria from our hand.
For this, I didn't washed my hand before experiment. (In fact, wash hands before experiments is required.)
And I rubbed my finger on half of my growth medium.
I can see there are more colonies in region 1 than region 2.
That means washed hands had less bacteria. But there are still few colonies so I could think that washed hands have still few bacteria.
Or I had touched something else after washing hands, before rubbing culture medium.
Finally I could exercise how to incubate bacteria.
