Thanks everyone! If you can get to them when they're young enough, you can twist them pretty much any way you like. 8-) I've often thought the instrument manufacturers should do something like this, but on a much larger scale. The cost would be relatively trivial compared to the number of kids you c...

On October 29th, I had my microscopes set up at a Science Fair Expo at the Riverside (CA) County Office of Education. Lots of displays and workshops for the kids wanting to do science fair projects. Many STEM experts, generally college professors, available for consultation with the students. Some 3...

Very nasty indeed.

The CSF finding was a big surprise, but not as much as the patient's survival. If I recall correctly, that was the very first survivor. So just like finding a massive number of malignant cells in CSF, pleural or peritoneal fluid, you're looking at a dead man walking.

Different amoeba, different target, different symptoms. Only just ugly, one almost always fatal. Entamoeba histolytica, GI symptoms usually, ugly diarrhea and sometimes organ (liver, etc,) abscesses. Abscesses may be fatal if untreated. Diarrhea ugly but most often self-limiting. Possibly fatal from...

Same thing for me. I think I was nine years old or so. I had a chemistry set too.

Bill,

Thanks! The subjects are listed in the first post on the subject here: viewtopic.php?f=6&t=3969

It is fun, and you're right about their expressions. I love the photos. When some of them come around the corner to exclamations of "Oh, microscopes!" you know you've got something good going.

Tom

zzffnn, The main interest in the forams and diatoms were "what are they" since they really had never seen anything like that. The louse slide probably got more good photos, and actually scared a couple kids since it completely filled the frame. 8-) There are a couple of problems letting them move th...

This is the last of the lot.

And now we have a whole bunch of new photomicrographers!! Not too bad for less than 30 seconds of instruction.

More photos from the STEP Conference. I could be wrong , but they seem to be having a good time!

Tom

There was a huge STEM outreach demonstration Wednesday and Thursday, Oct 5 and Oct 6, at the STEP (Science and Technology Education Partnership) Conference (http://myscienceeducation.com) in Riverside, Ca., at the Bourns Technology Center. Sponsored by Bourns, University of California, Riverside, Ab...

CmchPt, What apochronaut said, and: Your photos aren't useful for diagnosis. The mouth and throat contain so many different organisms that are normal flora that a culture is the only way to tell what is there that might be pathogenic, be it bacterial, viral, fungal, or whatever. Any worries about ma...

Thanks for the kind words everyone.
I'm really glad you enjoyed it!!

This video is a bit different from most. This is from an algae mat, collected using my plankton net from a slow moving stream. Not being an entomologist I was pretty clueless as to what kind of nymph it was, but was fascinated watching it crawl around in the Spirogyra. I decided that to ID it I woul...

einman is right. The Olympus BH-2 series are very, very nice microscopes. The very common DPlans are great objectives. BH-2's are very sturdy as well. Lots of parts available. I have several I use in outreach. I bought those as I had used them in a clinical lab for 20+ years and found them almost bu...

Metrophage, Don't worry about using a cell phone. Here's a link to an article I wrote awhile back for Micscape: http://www.microscopy-uk.org.uk/mag/artapr16/tj-cell-phone-photomicro.pdf It's a pretty thorough treatment on using a cell phone camera for still and video photomicrography, and has some e...

I have an SZH too. You're going to love it!

Tom

That's a BX series adapter that works fine with the BH series.
The Olympus BX standard hex wrench is 3 mm.

It's very likely normal, and it's not the condenser. Look at the camera live view output resolution. It's probably much less than the sensor is actually delivering to the file, particularly in older cameras. Even the sensor cannot deliver what your eye can see unless you are dealing with wavelengths...

I absolutely love the first one, but the shot down the "throat" of the Difflugia sp. test is view I've never seen. Very nice!!

Tom

If that's true, every single clinical laboratory is in serious trouble!!
Methinks someone is yanking your chain!

I'm happy everyone finds it as useful as I have. I was pretty surprised how well he demonstrated everything, and there is a LOT of information there. The modified Zeiss he uses is really a marvel, and the design of the modifications indicates he really knows how to teach. I found it to be very, very...

This link was posted a couple of days ago on the photomacrography.net Beginners Micro forum by GaryB. Peter Evennett does an excellent job of demonstrating, with a modified microscope, microscope light paths and image formation fundamentals. No math and no ray diagrams! Just a modified Zeiss microsc...

The manufacturer's website for the MA-500CK (http://www.amscope.com/5-0mp-microscope-digital-camera-compatible-w-windows-mac-os-4-scale-calibration-kit.html#product_tabs_description_tabbed) says the frame rate is: "30 f/s @ 640x480, 8 f/s @ 2592x1944 pixels" It doesn't mention anything in between. I...

Not quite... The specimen is smeared onto the slide, allowed to air dry, then mildly heat fixed, generally by flaming in a bunsen burned flame. My first microbiology professor told us to pass the slide (smear up) back and forth through the flame a few times, then lay the bottom of the slide onto the...

If you want to get rid of the circle, and fill the sensor with the image, you can use a digital zoom. Zoom in just enough to eliminate the circle, and then take the shot. It takes practice to hold it still, but it works pretty well. It will work very well if you have some mechanism to hold it steady...
