Winogradsky Column (Team 16)

Team 16 (Sotiropoulos Giorgos - Terpos Ioannis)

Hello Winobloggers,
The experiment was the Winogradsky column. We are a two person team from the University of Thessaly, Greece.  The experiment was held in Volos in the region of Anavros. We used a plastic bottle (1,5L), seawater (~500ml), an egg, pieces of newspaper and an amount of sediment from the beach.
  • Day 1 (18/3/2015)
 At the first day of our experiment we placed our column in a bright spot and sealed.

  •  Day 2 (28/3/2015)
After ten days we can see the water bluring and changing color and becoming yellow. This is a result of the photosynthesis of the phutoplankton.

Day 2
  •  Day 3 (10/4/2015)
In this image of the column we can see the color of the water changed in to bright pink. This is a result of the existanse of Calcium from the egg shell. The sediment begins to becοme black due to the presence of the FeS from the anaerobic respiration.
Day 3
  •  Day 4 (20/5/2015)
As we can see at the last picture the color of the water is between dark red and brown and the column is black with reddish dots because of the anaerobic conditions  in the column and the light.

Day 4

  1. Any idea why your winogradsy column is so different to that of your partners?
