GMU:DIY Biolab “Driver’s License”/Christian Wiegert: Difference between revisions

For the beginning i added 5ml of fertilizer to 1L of water and then filled 3 different jars with it. I had one with the lid on top, so this was fully sealed and only algae already inside the water could grow. On the other hand i was sure, that the water inside would not evaporate totally no matter what happened while i was away. I added a second one with an opened lid and a bottle which was somehow the step inbetween the others.
