Univ. of Thessaly, Group number 04 (Ev. Gousia - Chr. Gkizas), Day 0-50, Incubation: Dark

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 Anauros beach (Volos) (21/03/2016). We colected results of  50 days .

When the sample collected at the first day, into the bottle there were one broken egg, pieces of paper and sediment (brown colour) and water (light yellow colour) of the area.

 
After 7 days of the experiment we 've noticed that the sediment became black and a white substance appear in the top of it. The water colour turned to ligth brown.

DAY 7




After 17 days the sediment was black and the water became white. The thick, white substance at the top of the sediment has disappeared.



DAY 17



After 30 days the water became dark gray and a gray substance appeared above the sediment.



DAY 30



After 36 days no changes at the column.

DAY 36




After 50 days the sediment became more compact and black, and the colour of the water became dark gray.


DAY 50
