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