MICROBIOLOGY!!!

Here are some older assignments and pictures from the 2009-2010 school year. This information will be removed during the current school year and more items will be added/modified as the 2011-2012 academic year progresses. Therefore, this is a preview and is under construction so to speak... To help you learn the chapter 4.7 vocabulary, please visit Quizlet.com to practice/test on the 20 vocabulary terms. Here is the Link... media type="custom" key="5324627" In class on February 3, 2010 we visited this website to learn more about Growth Factors and Bacteria. Check out the Self Quiz to prepare you for a quiz in class on February 4th [|Growth Factors]

[|CHAPTER 3 QUIZ ONLINE FROM TEXTBOOK] Please click on this link to take a 25 question quiz as a 50 point test grade. Deadline is midnight on Tuesday, November 30, 2010 to submit for a grade.

Here are some examples of lab stuff... we started with a nutrient broth inoculated with a mixed culture of //Serratia marcescens, Micrococcus luteus, and Escherichia coli.// Next, we inoculated clean nutrient agar plates. The plates went into the incubator for a happy warm growing area. These are pictures of the agar plates after just 5 hours and 24 hours. The //S. marcescenns// is RED//.// The //E. coli// is White. The //M. luteus// is Yellow. The plate #1 and #2 had the Radiant Streak Technique performed and the plate #3 had the Quadrant Streak Technique performed. These are ways to isolate individual colonies of bacteria often called the loop dilution technique.

The next day in class, we performed the Gram Stain to help us identify the bacteria.

This was an in class assignment. Watch the YouTube Video and complete the worksheet. Want to see how to dilute a mixed culture to obtain a pure culture and/or count the number of microorganisms present? Watch this YouTube Video about Serial Dilution media type="youtube" key="MGwo_JvKzXE" height="344" width="425" We did this as an in class assessment. We watched two videos and completed this worksheet Want to know how to perform the Most Important Staining Technique in Microbiology? Watch this YouTube Video... media type="youtube" key="OQ6C-gj_UHM" height="344" width="425" Here is video #2 - it is silent. This is the one we were "tested" on in class...media type="youtube" key="syJTy8C_BG0" height="344" width="425"

Here is a copy of Test #1 for Microbiology 2009 given in class on 10/8/09

Please view this PowerPoint Presentation on 8 Invertebrate Organisms we saw in the lab under the microscope. Do you know the difference between animals and protozoans? This should help.



For a content Drop Everything and Read day, microbiology students read about Robert Koch on paper and on the computer while accessing the internet. Here is the printout and a website link for information about Robert Koch [|The Works of Robert Koch]

Using Fodey.com we created Obituaries for Robert Koch who is a very important microbiologist based on the DEAR article and website visitation. If not for Rober Koch, we would not have the ability to culture microbes in the lab like we do today. Here are some of the writing samples after reading some information about Robert Koch:

During that same DEAR period, we read about Amazing Potatoes! Here is a website to learn more about how awesome potatoes really can be... [|Potato Extract]

We wrote Odes to Potatoes - What is an Ode??? Check out this site to know more... [|Ode]

Since potatoes are so wonderful and we learned more about them, here are two samples from class...



Below is information updated from the 2008-2009 school year at Bellwood-Antis. On March 24, 2009 ~ Microbiology Students used the Ouchterlony Technique in the microbiology lab.

Here is some information about how to carry about the lab procedures to obtain the "results" that we saw in microbiology... This information is from Wikipedia.

[|A gel plate is cut to form a series of holes in the gel. An extract of human cells, harvested from tonsil tissue, is placed in the center well. This extract contains a cocktail of natural human antigens that we wish to look for. The patient's serum is then placed in one (or more) of the outer wells and the plate left for 48 hours to develop. During this time the antigens in the tonsil extract migrate in a radial fashion out of the center well and the antibodies in the patients serum migrate in a radial fashion out from the peripheral wells. When the two antigen fronts meet, if there are antibodies in the patients serum to any of the antigens in the tonsil extract, they will bind to the tonsil antigens and form what is known as an immune complex. This immune complex precipitates in the gel to give a thin white line. When more than one peripheral wells are used there are many possible outcomes based on the reactivity of the antigen and antibody selected. The zone of equivalence lines may give a full identity (i.e. a continuous line), partial identity (i.e. a continuous line with a spur at one end), or a non-identity (i.e. the two lines cross completely).]

Here are the students in period 4 Microbiology's results:

Here are some news articles created by Ms. Shimel's 4th period Microbiology Students in March of 2009 after reading and hearing NPR broadcasts about recent changes on Stem Cell Research concerning President Obama.
