UCA_10A_1: Day 14

Rio San Pedro sediment+paper+1.5g FeSO4
We had made our Winogransdy column as follow: we added some Rio San Pedro sediment wich contains wood sticks and some little rocks. Then we added 1.5g of FeSo4 , and two pieces of teared paper with is made of cellulose. We moved all this ingredients and put it all in our plastic bottle, until fill the 3/4 of our bottle. We conclude our preparation adding water found in the same place where the sediment was pick up, completing the last 1/4 of the bottle.
We put a lid on our bottle slightly and then we put our bottle in the dark zone of the laboratory. We classmates put theirs in an illuminated zone next to a window.
Day 14 comment:

We observed our bottle, it looked different. We found a lot of black and dark patch all over the bottle(Figure 1), and a big made on the bottom. It was microorganisms, a bacteria wich transforms the inicial FeSO4 in FeS by their metabolism, we have to remember that all this happened in a anaerobic medium, without O2... That´s all about our first revision of our bottle...Hope you read us the next days! Enjoy our ''coloring' pics... We'll post information soon!!

  1. It will be nice if the black spots increase!!!! and if they do, how fast...?

    1. Yes it would be nice...but at the moment our column looks the same, the black bacterias haven`t grown no more!! hi from Spain
