Hello everyone, we´re back a week later to check the progress of our columns.
As we can see in the image, there are significant differences between both columns:
- The column that had the teaspoon of salt didsfavoured the growth of microorganisms, maybe because of the osmosis.
- In the column that hadn´t the salt we could appreciate a larger dark area at the bottom which is caused by microorganisms so we could say that they grew better in this column.
As we mentioned in the last blog entry, both of our columns were exposed to sunlight so that it wasn´t a variable. It was done in this way so we could see how the salt affects the growth of microorganisms.
Welcome to the Winobloggers webpage! Students and professors from different universities meet to discuss their findings on Winogradsky columns they constructed! We learn how to formulate hypotheses, observe, comment, ask and reply to questions related to our scientific experiments.

How do you know that there are less bacteria in the sediment growing?
