Winogradksy column
Team 14 (Papaioannou Aristeidis-
Papadopoulos Panagiotis)
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: one plastic bottle of 1.5l, one
plastic bottle of 0.5l, one egg and Some small paper pieces. we
left our columns in a light place and took some photos during the days of the
experiment.
Day
1.
At the first day of our experiment we placed our
column in a bright spot.
Day 4.
After 4 days we noticed some
changes in the colour of the water. It became more yellow.
Day 47.
The black color of the
sediment is caused by the presence of FeS from the
anaerobic respiration.
Day
55
We can see the
black colour of the sediment in the whole bottle and the cloudy water because
of the anaerobic conditions in the column.
