500x total magnification microscope; What is best source for water to see interesting microscopic life?

well any water will have life in it except bottled. the best would be from a pond, stream, or river. or the ocean if you live near it. Have fun.

In general, the best money for the aperture (the amount of light the telescope takes in), is a Dobsonian-style Newtonian. They are significantly less expensive than refractors with the same light gathering power. As for brand, etc., as long as you get it at a place that sells primarily cameras/telescopes/binoculars, you should be fine. Avoid department store/Wal-Mart telescopes; they may be cheap, but that's what you get. The sources provide a lot more information.

Burn it in a sprectrophotometer.  Look at the emitted light.

Adding to the above... If you can afford it and you want more than about 7x magnification, you should consider buying IS (image stabilizing) binoculars.   These need batteries, but dynamically correct for the shaking of your hands.  You can get them up to 15x magnification.\n\nAlso, it's important to consider what you want to use the binoculars for.  If you're going to use them at comparatively short distances, you don't want a pair that magnify too much because you'll have to keep moving the glasses around to see entire objects.  (That's why opera glasses, which are a form of binocular, are such low magnification - typically 2-4x).   Also, if you plan to use them at night or in low light, you want a large objective lens size (50mm or larger) because that allows the glasses to gather more light.\n\nLastly, if you'll use them in unstable situations (like a moving boat), consider the size of the exit pupil.  This is the objective diameter divided by the magnification, and measures the diameter of the image which your eye looks at.   This is important because it affects how precisely your eye has to be lined up with the eyepiece for you to see the image.

you can try total internal reflection of light using a keychain laser (commonly availble) and tub filled with water. all you have to do is put a small piece of mirror in the tub filled with water, let laser fall upon it. see the trajectory of the reflected beam ofr different orintations/angle of reflections and you will find that for certain critical angle the reflected beam is trapped in the water due to the internal reflection of the laser. you can do the same thing by choosing a transparent bottle with a small hole on the curved surface close to the base. now fill it with water, and see that water flows out of the hole in a parabolic fashion, now shine the laser from the opposite side to illuminate the water column. take a white plastic sheet allow the water to fall upon it, you will find that the water emmits light. this also explains how fibre optics work.

You could, but it would be huge overkill. The telescope's objective (lens or mirror) limits the resolution of the image in the focal plane. So you'd be using a microscope to examine (at huge magnification) that resolution-limited image. You'd see nothing but a lot of fuzz, even when in focus; and it would be dim fuzz at that, because you'd only be capturing a tiny fraction of the available light.\n\nI'd stick to standard eyepieces.

see how much weight each surface can hold up. I know u can keep a needle afloat in a cup of water. Although the experiment would depend on what kind of paper and how damp it was.

Look for water mark images by holding up to the light.  Look for plastic strip. Look for color changing ink,etc.

they are cheap compare to electron microscope.\nbut there is limitation of zooming large.

You should be able to observe human sperm with any magnification above 100X. Although to get any detail you would need around 300X.

false. Are you looking for others to answer your homework? just type in diatoms and read about them. They are facinating, especially under the microscope. You may have some diatoms in your pool filter-called DE, diatomaceous earth, they help keep the water crystal clear. Read about them.

one option is to freeze the water, shape it into a concave lens shape, polish it till its transparent, and use the disk like a magnifying glass on the match head.\n\ni saw this actually done on myth busters, although it didn't go very well

put bacteria under a microscope and hook it\nup to a pc and project  it would be COOL!!!!!!!

You have to start with Anton van Leeuwenhoek. This Dutchman was the first man to use a microscope to view water and saw the small animals living there. He is called the father of microbiology according to wikipedia.

You can get a hollow prism, fill it with water or some liquid and find its refractive index using a spectrometer. I did that for my ISC exam.

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.
