Volos_Group 19_Day 10_Light

  Our names are Vasiliki Papadimitriou and Nikos Danavaras and we are undergraduate students from Department of Ichthyology and Aquatic Environment, University of Thessaly, Volos, Greece. We are presenting our results from Winogradsky column experiment that was conducted in 21/03/2016 at Anauros beach (Volos).

  • 1 egg
  • pieces of newspaper
  • 1 plastic bottle (1,5lt)
  • mud from the beach
  • sea water
  2/3 of our bottle contain mud mixed with one egg and some newspaper pieces and the rest of the bottle is filled with sea water.


  In the first day of our experiment the water is clear and has a yellow colour.


  In the third day the water is less clear and has a light yellow colour. The water level is higher compared with the water level in the first day and in the surface of our bottle there are some bubbles.


  In the fourth day the water is quite turbid and its colour is more white. The water level is higher and has reached the surface.


  In the seventh day the colour of the water is more white but in the space between the water and the mud, it has created a thick white line. The water level is lower compared with the previous days and our sediment has black colour.



  Today (10th day) we can see that the water is still turbid and its colour is darker. We can also see the thick white line that was created three days ago. The water level is higher compared with the water level in the seventh day and the colour of the sediment is darker now. Finally in our bottle it has created a thick surface layer.
