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.
