Cadiz, 1A: WINOGRANDSKY COLUMN, THIRD WEEK RESULTS- GROUP 1A

Hello, last week was the third week since we made the Winograndsky Column and there were new changes!

Orange colour has been magnified maybe because of the passing of time. Orange areas are a result of nonsulfur bacterias, which need a carbon source to thrive. The carbon these bacterias use is obtained from the paper we added to the bottle.

Then, dark areas have been magnified too, so that means that sulfate-reducing bacterias keep working. The halo we can see around that areas maybe the hydrogen sulfide gas they make as a result of the consumption of sulfur.

We can't see any difference in the surface which keeps the typical sand colour.

There's a difference between the dark side and the light side and it's that the different areas' colours in the dark side are less colourful than in the light side. We think it's because of that part of the bottle receives less sun energy so that they can work weaker than bacterias which receive the sun light.
