Agar plate

Method: Purpose: To investigate how Porcellio Scaber reacts in terms of orthokinesis to different humidities in their habitat. Equipment-  75 slaters which range from 5-10mm in length (kept in a plastic container with holes in the lid, with dirt and bark so that they are kept in a natural environment as possible so can react naturally during experiment.)  5x petri dish set ups labelled from 50-90% (One petri dish on the bottom will contain glycerol and have a mesh/gauze hot glued over top…

Coliscan easygel nutrient broth was stored in the freezer. Around 24 hours prior to sampling, the broth was moved to the refrigerator to thaw. The sampling procedure follows the procedure stated in the Coliscan Easygel Instructions. When we were ready to begin sampling, the thawed broth was placed into a cooler. We started sampling at Cornerstone pond then move to the Wyoming site, then downtown Grand Rapids, then Plainfield, and then Versluis lake. The procedure for Cornerstone pond and…

think there were some errors in our environmental sampling lab. Something like completely removing the lid of a petri dish can alter the results because it can allow the air to contaminate the agar. Not properly swabbing the sample can also affect the results because you may not transfer any bacteria onto the agar. Lastly, I learned that since bacterial growth can be found almost everywhere you go it is very important to wash your hands. To remove bacteria from your hands, you should wash your…

The End Zone: Measuring Antimicrobial Effectiveness with Zones of Inhibition Introduction: A Kirby-Bauer test is a microbiological method used as a form of testing bacterial resistance, it’s also known as a Zone of Inhibition test (1). The way in which the Zone of Inhibition was determined in this experiment was by measuring the diameter of the resisted zone in 3 areas and taking an average. As numerical data was required for this it means that in this experiment the Zone of Inhibition Test was…

of individual groups with distinct boundaries which match the assumed physical characteristic for each group. It is important to note the large increase in the number of fungal colonies as well as the decrease of bacterial colonies in the Mycophil plate both of which account for the discrepancy between the two percentages of fungal colonies present. Table 2: Percentage of Fungal colonies present, over the total number of colonies present. Section data is an average of the results of the…

The region is tectonically characterized by the ~6 kilometer thick oceanic Nazca plate subducting underneath the continental South American plate at a convergence azimuth of ~ 78 ͦ and at a rate of 6.6 centimeters per year making the area one of the most active convergent margins on earth, typically experiencing a Mw > 8 earthquake every 10 – 20 years (Moscoso, et.al., 2011). Notable quakes in recent history include the 1960 Mw = 9.5 Valdivia earthquake which was the largest ever recorded,…

lesson will teach the student about fault lines and boundaries where two separate tectonic plates meet, and why volcanoes are formed. Begin with a brief introduction of the theory of plate tectonics. Explain to the class that plate…

This essay on supercontinents was a tough piece to write about, but it was fun and I enjoyed writing about it. I had to think scientifically, but I also had to consider the audience on writing this paper. I had to go back and ask myself multiple times if the audience would understand this and be interested in reading this. I had to ask if this was too confusing, and if it was, what could I do to make it clearer and easier for the audience understand. This was probably the toughest essay out of…

A Hurricane is a tropical cyclone or tropical storm that forms over in the Caribbean Sea, Gulf of Mexico, Southern Atlantic Ocean and the eastern Pacific Ocean. Close to the earth 's surface a cyclone is accompanied by thunderstorms and a circulation of counterclockwise winds. Hurricanes can hit the gulf Mexico and all of the Atlantic Ocean. Every year the Atlantic hurricane season starts on May 15 and will always end on November 30. Hundreds of miles inland and coastlines, hurricanes can cause…
