Filter Frenzy
The day we received the testing kits, we got started right away. Before, we did anything, both testing tubes of the Anabaena collapsed. Anabaena is a genus of cyanobacteria, also known as plankton, which is usually found in shallow water or moist soil. Anabaena is very sensitive. And due to the change of being in a dark, confined place to being brought into the light, the Anabaena fell to the bottom of the testing tube. While, the Microcystis, a genus of freshwater cyanobacteria remained the same.
Our main focus throughout the process is the Microcystis. It will prove that daphnia eliminates cyanobacteria specifically in freshwater. Microcystis is known for how harmful and dangerous they are.

Daphnia teriminates Cyanobacteria
This is a picture of the testing tubes straight out of the box before we did anything to them. The two on the left are Microcystis. While, the two on the right are Anabaena. (As you can see the Anabaena is all at the bottom of the two tubes.)
First, we took a cup of daphnia from our own culture of it. Then, we put a certain amount of daphnia in each tube. The tubes are labeled and identified by how much daphnia it contains and which type of cyanobacteria it is, Anabaena or Microcystis. Finally, we’ll keep track of the daphnia day by day to prove daphnia kills cyanobacteria.
