Hello, we are groups B1 and B2 and we are going to explain how we made a Winogradsky column experiment.
First of all, we added 20g of mud in our test tube. Later we mixed the mud with a little bit of San Pedro´s river water trying to get a viscous texture. The next step was adding 0,3g of paper and 0,1g of CaCO3. We prepared a 100g of sand and 20g of mud mix and we cleaned the test tube edges. In this moment wee got a 2 cm layer of water.
Hypothesis: The aim of this experiment is checking how the concentration of salt affects to microorganisms. For this, one group prepared a Wingardsky column without salt and the other group added a teaspoon of salt. Both columns were exposed to the sunlight.
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.
