Univ. of Thessaly, Group number 26 (Stamopoulou - Sountoulidis), Day 0-53, Incubation: Dark

Our names are Theano Stamopoulou and George Sountoulidis and we are undergraduate students in the Department of Ichthyology and Aquatic Environment, Agriculture Science, University of Thessaly, Volos, Greece. We are presenting our results from the Winogradsky column experiment that was conducted in at Anauros beach (Volos) (21/03/2016). We colected results of 53 days .

The first day the sediment had a ligth brown color and the water was ligth yellow

After 7 days of our experiment we 've noticed the first significant changes in our column. The sediment became darker. The water in the bottle turned into white and a white substance was created at the top of the sediment. 


After 20 days the water in the bottle turned into light grey (first picture) and a white substance was created in the surface (second picture). The white substance at the top of the sediment has disapeared. 

DAY 20

 After 30 days the sediment became darker (first picture)  and the substance at the top of the bottle was thicker and whiter (second picture).

DAY 30

After 40 days : We didn't notice any changes.

DAY 40
After 53 days only the colour of the sediment became darker.
