expº 2 progress

This is the second set of experimentation I did, and now significant results can be observed.
I made 5 plates, each of them set up in different conditions.

In the first plate, I passed a 5V current though the agar. Throughout the growth, colonies started to grow separately from each other, very condensed and isolated.

Unlike this next one, where it was kept within room light/temperature. The growth was vast and 'messy'.

This next plate was kept in total darkness during the whole experiment. The result is somewhat similar to the plate with electricity.

This one was kept under heat produced by 2 small tungsten bulbs. The growth was very fast and spread uncontrollably. After a few days, the bacteria stopped growing - maybe too much heat/light? There was a lot of condensation in the plate.
