At this observation, distinct algae types could be seen in the bottom layer of the MicroAquarium. Algal growth increased since last time. Spirogyra were present, as well as motile; single-celled; circular green algae that moved quickly. Diatoms, different types of Chlamydomonas, and organisms which likely were Desmids were observed in the muck layer.
Various types of Rotifers and Ciliates were common in both the bottom layer and the left side of the above layer. Much algal growth and several Ciliates were present in the right side of the MicroAquarium, though there was generally less activity in this region.
These observations can have the effect of impressing upon one a sense of the aliveness of the surrounding world. While many would look at a puddle of water, or a bit of pond sludge and perceive it as inert, inanimate... a project like this one is an introduction to the presence of the diversity of life which cannot be observed with the naked eye but is very much there nonetheless.
