We are Mladeni Sofia and Micheli Sofia and we will
present you our results between first days to 52th day. Our experiment started at 21th of March on
Anauro’s beach. We took the sediment from the bottom of the sea and
mixed it with pieces of newspaper and a
broken egg. We filled the 2/3 of a
plastic bottle with the mixed sediment and filled the rest with sea water. We covered the column and placed it behind a window. The first days the sediment had a light grey-brown color and the water was
light yellow (because of the broken egg). As the days passed, the color of the
sediment began to darken until it became black. The water became after a period
of 20 days it brown and now it is black.
