After observing the pond water slides we saw:
Oranism 1: Filamentous Green Algae
Domain: Eukaryote
Kingdom: Plantae
Division: Chlorophyta
Genus: Spirogyra


Characteristics:
-Contain Chloroplasts
-Lack flagella
-Contain cell walls that are connected in long chains
-Can move
References:
-Guide to Identification of Freshwater Microorganisms
-Wikipedia

Organism 2: Cyanobacteria
Kingdom: Bacteria
Phylum: Cyanobacteria
Genus: Oscillatoria


Characteristics:
-Oscillating movement
-Filamentous
-Reproduces by fragmentation
-Produces oxygen as a byproduct of photosynthesis (like other cyanobacteria) 

Organism 3:Daphnia
Domain: Eukaryote
Kingdom: Animalia
Phylum: Arthropoda
Subphylum: Crustacea
Genus: Daphnia


Characteristics:
-Visible compound eye
-Transparent body which allows you to see all internal organs
-Intestine that runs from mouth to anus
-Antennae that are used for swimming (hard to see in picture)
-Jerky swimming motions (couldn’t get a video)
-Body is of a round shape that is most similar to Daphnia

Organism 4: Volvox
Domain: Eukaryota
Kingdom: Plantae
Phylum: Chlorophyta (gave rise to land plants)
Genus: Volvox
Common Name: Green Algae


Characteristics
Volvox is a polyphyletic genus of chlorophyte green algae of the family volvocaceae. Volvox form spherical colonies The cells within a colony are contained within a gelatinous wall made of glycoproteins. Volvox contain two flagella, which they use to move through the water. They are photosynthetic. Volvox reproduce asexually daughter colonies are produced within parent colony and produce colonies through repeated division. .

  1. I wish you guys made this post more compact to make us easy to see. All the descriptions and then pictures works hard to me to see. And please give us link for the Wikipedia or Google site which you guys used for reference to see what you guys used next time. Just my personal opinion. Thank you :)

  2. I would love to see the daphnia moving. Maybe next time, you guys can take a video of something moving. Also it is also cool to see that it has a transparent body which makes us see the internal organs. Although in the picture it is not clear, I would still be curious to see how it looks like. Maybe you can send us a link/picture from google. Well anyways, you guys still did great :P

  3. Looks like your filamentous green algae could be a spirogyra, if it had the spirals internal to its cell membrane would be good evidence of that. Appreciate the highlighting of the organisms within the pictures.
