How do I show bacteria from the mouth for a science project with out a microscope?

If you have access to a petri dish and some agar you can swab the inside of your mouth and grow the bacteria on the agar so it will show up to the naked eye.

I'm a biology teacher, and a cell model is a project every year.\n\nUse a HARD beachball about the size of a basketball....or a cheap dimestore basket ball. Cut in in half and use thin wires to suspend the various organelles inside.

Boil ¼ cup of water. Add one teaspoon of gelatin and one teaspoon of\nsugar. Stir for one minute until everything is dissolved.\n2. Cool the solution for ten minutes.\n3. Fill a petri dish to a little below the top edge.\n4. Close the petri dish by putting on the cover immediately. Let the\ncovered petri dish stand for at least four hours. Don’t touch the\ngrowth medium or you’ll add your own germs!\nThis recipe will fill two, small petri dishes. If you and your class plan to fill\nmore petri dishes, make more germ food by increasing the amount of your\ningredients proportionally.\n*Adapted from Gross But True Germs by Luann Colombo. See details in bibliography. If you don’t\nhave the materials needed for the experiment, you can purchase Ms. Colombo’s book, which includes\nall the supplies needed to conduct the experiment.

uh, well, one time my friend and I had to do a project like that.  We got two of those clear bodies (you know, the mannequins they have that display clothes.)  You can get clear ones at Sam's club for free, if you know where that is.  We made a model of the body.  Like, we used straws for the intestines and a bowl for the stomach.  On the other body, we used sharpie and labeled the different parts.  (We also drew them)  Then we got a medicine dropper and put water mixed with food coloring in it.  We poured the water/food coloring down the first mannequin's esophagus.  Everyone could see it going through.  It was really cool and we got an A+!\n\nAlso, explain what's happening as the water/food coloring goes down.  Don't forget to put a bowl underneath, or else the water/food coloring will spill.  I guarantee this will get you a good grade.

The simplest way to determine wether a water sample has microbes or not is MICROSCOPIC EXAMINATION ie,to view a drop of that water under a microscope and observe for any micro organisms.

Take various juices and put food coloring in them. Have some students taste the juices and see if they are fooled. Copy that down and make a chart for every juice and how many were fooled and not. It should be interesting. (I suggest water into purple to look like grape juice...and so on for others)

i did this, i used a ball of styrofome( er however you spell that) for the whole cell, and a smaller ball for the nucleus. then i just found a buncha little things for everything else. i used toothpicks with little tags on the end to label the parts

Thats quite a platefull there...\n\nI'll help out with a few, afterall... it is your research project.\n\nThink of your common respiratory illnesses... bronchitis, flu, cold... etc.  Then I'd run a search of other respiratory illnesses, pneumonia for example (bacterial AND viral).\n\nHandling of specimens... you should know the aseptic technique.  And your major rule in the micro lab... Treat every microbe as if it were a pathogen.\n\nTypically... you bacterial diseases are cause by Gram Negative bacteria, to isolate those guy you'd grow them up on Mackonkey's Agar.  You can use a number of selective/differential mediums to help isolate your pathogens.\n\nVirus needs to be cultured up similar to parasites... cell culture.\n\nTreatments vary... though most commonly you'll see antibiotics (even when the cause is not a bacteria... thank you very much Doctors...grr)

Yes, you need a lab to do this! If that wasn't clear to you, this may not be the best project to try to copy!\n\nWhy not have an idea of you own, something you can do with what you have at hand at home? You might learn something!

macroscopic. you "farm out" the bacteria on a agar plate, then describe what grows (usually after 48 hours, but can both be more or less- depending on the species)\nNote: there are VERY many possible culture media (usually Agar based), and some bacteria will grow only on a few of them- that helps with the ID\nAlso- some bacteria need special culture conditions- eg. anaerobes- which die if they are cultured in contact with air. Also helps with the ID.\n\nMicroscopic. First of all look at the bacteria under a microscope- that gives you some info.- eg are they round (cocci) or elongated (bacili) or curved (vibrio) or spiral, or any of a multitude of shapes.\nsome bacteria are transparent and can only be seen in a "dark field" (reflected light from bacteria seen on an otherwise unlighted space) typical for Treponema pallidum- causes syphilis.\n\nThen the bacteria can be stained- very many possible stains and methods- but the most commonly known is the Gram stain (hence some bacteria are called "Gram positive" or Gram negative" - depending if the stain "caught" on the cell wall.\nSome stains are then removed with acid preparations- and in some bacteria it works, in others not. eg. the TB bacteria are known as "acid fast"- meaning an acid bath does not remove the colour of the original stain\n\nEssentially you are supposed to go through all the steps and look up in a book what fits your particular bug.\nThe bug can also be a fungus- yeast or mould

Hmmm... judging by your interest in cleaning products and dishwashing detergents, I'm guessing you're in that industry or just a student looking for some answers for a project.\n\n-Insufficient data - \nAre you referring to dishwater in a more sterile kitchen or a dirty restaurant?  Is the piping clean or are we talking rusty piping?  Filtered water or non filtered water? Hmmm... so, at STP you want to figure out this. \n\nHere's what you would need.  First figure out the type of microbes that would typically exist in your sink.  Or if you don't have one, get some kind of bacteria.  Take the whole thing, perform your experiment.  Take some water samples.  Finally, send the water samples to a lab immediately for a count.  You could get a concentration of microbes per given volume.  My advice -- it's all I can do.

You could do serial dilutions and plate from the dilutions and then extract one of the plugs from the plate and let it sit in some media with a bacterial culture and incubate till it clears. Then put the culture in tube with chloroform and place on ice for 15 mins. Centrifuge it for 20 min at 25000 rpm and remove the supernatant and that will give you a bacteriophage stock.

E coli loves a basin or the floor or basically anything that has food for it. I suggest you go to a store that sells scientific equipment and buy a petri dish with agar gel in it. Agar gel is a substance that enables bacteria to grow on it. You should take your sample and gently rub it on the agar gel, but be sure that you do not let the dish be exposed too long to the air, because bacteria is everywhere and you might get some unwanted cultures on your dish.\nYou must then keep the dish at room temperature for at least three days. \nThe E.coli will be visible on the agar gel, but for best viewing of the culture, a microscope is needed, because without it you will only see a yellow line where you rubbed the sample.\nA microscope is a scientists best friend, because with that we can see worlds that other people did not even know existed. you definitely need a microscope.
