WINOGRARDSKY COLUMN (TEAM 18)

Team 18 Konstantina Danae Chalkia-Eirini Aggeliki Charoudi Hello Winobloggers, We are a two person team from university of Thessaly in Greece and we are doing an experiment with the Winogradsky column.The experiment took place in the area of Volos Anavros.We used 1 bottle(1,5 L) from which we removed the upper part, seawater (~500ml),1 egg ,pieces of newspaper and an amount of sediment from the beach of Anavros that covered the 1/4 of the bottle.


  • FIRST DAY(18/3/2015)









At the first day of the experiment we placed the sealed bottle near to the window in order to be exposed to the sunlight.


  • AFTER 2 WEEKS

At the bottom of the bottle started to apear small black spots due to the appearance of the FeS from the anaerobic processes which are taking place inside the column.The colour of the water hasn't changed.

  • AFTER 4 WEEKS






The black spots have spreaded at the sediment but there has not been noticed turbidity in the water.
