Hi Winobloggers!
This experiment was about Winogradsky column. The experiment took place in Volos in the region of Anavros. We used a plastic bottle (1,5L), seawater (500 ml), pieces of paper, some sediment taken from the beach ang an egg.
8 days after
After 8 days of the experiment the sediment was darker and we noticed an almost white colour in the surface of the water.
20 days after
After 20 days the sediment was darker than before because of FeS.
