Zebrafish, February 4th
Like last week, we fed and took care of our zebrafish. By the end of this week, there was only one fish alive, and it was in the experimental group. The other dead fish have begun to dissolve and disintegrate into their wells.

Zebrafish, Week 2
Performed February 26
Over the course of this week, we observed, fed, and took care of our zebrafish. Every day they were fed brine shrimp, had floating particles taken out, and had notes taken on them. Overall, we began to see a decline in live fish over the course of the week, which could have been due to the small wells they were living in. The control group had less deaths than the experimental group. There are some pictures of the developing fish on the link below.

Zebrafish Experiment PERFORMED FEBRUARY 19TH 2016
This week, we set up our zebrafish embryos for observation over the week. 20 Zebrafish embryos (at about stage 10 of development) were placed in a control group, with only water. Another set of 20 were placed in an estrogen mimic solution as our control group. Throughout the week we will continue to go back to the lab to check on them, remove their egg case, and add more water if it evaporates. Attached is my instagram account with pictures of the setup, and a developed zebrafish.

Invertebrates, Week 6 February 17 2016
This week, we set up a Bernese funnel, which is a funnel that is filled with debris from out transect, including dirt, leaves, sticks, and other organic material that funnels small organisms into ethanol.. After waiting a week, we took samples from the top and bottom of the ethanol tube and but them in different petri dishes to observe. We used a dissecting microscope to identify the organisms. Pictures and descriptions of these organisms can be found on the instagram account linked below, along with an invertebrate description table.

Microbiology and Identifying Bacteria February 2nd 2016
The purpose of this lab was to quantify the number of bacteria in our hay infusions, diversify and observe the bacteria, to test for naturally occurring antibiotic resistance, and to identify the bacteria. PCR and DNA sequencing was done to verify our identificaiton of the bacteria.
For gram stain, bacterial smears were added to slides and then stained and viewed under a microscope. For the PCR amplification, we added primer mixture and the bacterial colony that we wanted to colonize into the tube and shook it up and places it into the PCR machine until next week.
Bacteria Colonization- (White bacteria) round, half-circle dots on plate. Usually larger. Gram positive. (Yellow bacteria) small, flat dots. Gram -

Protists and Algae
January 22 2016
Hay Infusion (After one week)
Smells rancid,
Something (mold, bacteria) growing on sides.
Protists samples came from the top and bottom of the jar, once split in thirds. This was done to see the different types of algae and protists If the jars were able to sit for longer, they may grow colonies of organisms and reproduce.
