Season three premiered on June 17, A televised MySpace audition also took place. Season three differed from the previous two in many ways. Auditions were held in well-known theaters across the nation, and a new title card was introduced, featuring the American flag as background.
The task of the lab experiment is to be able to set up an experiment in order to examine environmental toxins and how their effects on Tetrahymena. This was accomplished by using knowledge from prior labs to set up serial dilutions of Tetrahymena in different solutions, water in proteose-peptone-tryptone PPT media and insulin in PPT media, and counting cell numbers.
The labs prior to this week have prepared the students to engage in their first scientific experiment and were completed to help minimize errors. However, developing the metacognition that persistence in the face of failure will yield meaningful results.
Procedure for Experimental Setup Determination: Inoculate the Tetrahymena culture in a well plate with PPT media.
Acquire an aliquot of Tetrahymena culture, sterile PPT media, and sterile water. Carefully shake the well-plate. Data for Experimental Setup Determination: Do this three times to create a total of three testing wells.
Do this three times to create a total of three control wells. Initial Data for Concentration Preparation and Experiment: Insulin Test Well 1: Overall Insulin cell count: The lab was successful, but errors were probably committed. The dilution counts have a significant deviation and so does the data.
The cell counts were so large that counting them was inaccurate. The lab was not a complete failure but learning from these mistakes will help the students garner that metacognition mindset that failure can lead to success through trial and error.
Observing the data both before and after a day shows that insulin may negatively affect cell growth. For future experimentation, the lab should probably be repeated with different dilution factors to ensure more accurate counting.
The insulin added to the Tetrahymena culture should also be increased to accurately support the conclusion that insulin negatively affects cell counts.Hearing-impaired child climbs on stage to play during Pope's audience Teen films roof surfing stunt before tragic fall from Uber Melania and Donald at the White House for the Christmas reception.
