Our names are Betsiou Maria-Soultana and Biltsari Joulieta and we are undergraduate students of Ichthyology, UTH university of Volos.
I'm presenting our first results from the Winogradsky column experiment that was conducted in 21/03/2016 at Anauros beach (Volos).
We made one column from a 1.5 L plastic bottle which by 2/3 contains mud from the seaside mixed with enrichment materials (1 chicken egg with its shell and some newspaper pieces). After the column was filled to the mouth of the bottle, the mud precipitated and a zone of water was created occupying 25% of the column. The bottle was put in conditions of no light intensity and temperatures of 15-20°C.
Today, 5 days after the column was made not much seems to have changed. The mud seems to still be the same and the water took a light yellow shade. I will make a new post when something changes!
