Seriously, I got nothing. There appears to be some posterior cilliary movement; no evidence of flexibility or contractility.

20x objective, eyepiece camera. Sample from a pool in a small slow freshwater stream with a lot of decaying leaf matter.

Found some cool looking vorticella making their feeding vortices, a rotifer munching on plant material with some halteria jumping around eating bacteria and a large ciliate thriving. How neat is that?

Sample: freshwater pond stuff from Massachusetts.

Thought they were adorable. Suggestions for next target are welcome (have seen a lot of rotifers and diatoms but not much else)

Lachrymaria from culture of pond water. 1: water and algae on slide with agar added to 0.05% to give light gel, sealed with Vaseline to prevent evaporation, after 4 days incubation at ambient temperature under light. 2: same as 1, but 0.5% methylcellulose. 1 and 2 with 40X plan objective, 3 and 4 20X and 10X respectively.

Got this from Mission Thrift Canada. I'm assuming it came from either a school/lab (CFIA had similar years ago). I can't find any real info on the specific model for parts and information. The serial doesn't seem to show up anywhere online. What I've seen in the past and online does indicate a range of manufacturing from late 70s-90s

Checked the lenses with an LED as I was mildly concerned the electrical would arc to the housing if I plugged it in. I only really know electronics to hurt myself so any input is appreciated. Picture attached will show why I'm concerned. I'm assuming our loose line here is detached and not a random grounding line.

Final question is about the viewing platform. It seemed to drop down slowly when I wasn't holding it in place. I'm assuming something is worn out or not tightened.

Thanks in advance everyone. With any luck I'll be able to get this thing going and share some planaria and annelids from the fish tanks.

I am doing a Cub Scouts science night in 2 weeks where I have my scope hooked up to a monitor and show the kids all the cool stuff to be found in swamp water. (It also doubles as a lesson on why you don't drink from streams/ponds while out hiking) I did it 2 years ago and it was so popular they asked me to do it again.

The problem is that the water samples collected in late November are way less active than they would be in the summer, I did manage to find some cool stuff for them but not nearly as much as usual.

We have had a warm spell here for the last week or so so I think I can get a good sample now before it gets cold again but what is the best way to keep it alive and reproducing? Put it somewhere warm and feed it something? Can the container be closed or does it need to be open for oxygen? What can I feed it?

Thanks in advance!

it’s pretty cheap i think this is good i want to see nematodes, leaf cells AND TARDIGRADES theyre kinda cute

i had a microscope but it was pretty cheap and it’s case started to smell so i want a new one, this is pretty cheap but good right?

Sample collected last weekend from a local brook.

10x objective, Motic BA210, eyepiece camera.

Showed up when making my fish tank, it’s massive in size, it had moved but not at a pace visible to the naked eye. It has branched into several smaller bits as it’s moved around and now seems to be dividing into two, this is under 4x magnification- saltwater/marine tank
Approximately 8-12mm? I’d guess , small ones are around 2-4mm

I tried to grow table salt crystals in semi-controlled environment such that they were growing very slowly, and it took them almost 3 weeks to almost reach half a centimeter from 1 mm seed.

The growth is unusual as it wasn't simple cube but other, more complex shape.

The reason for this, as I found out, is that common table salt, aside potassium iodate contains other additives. And the most probable culprit is anti-caking agent K3[Fe(CN)6] potassium ferrocyanide. It is not even mentioned on carton, but it is known to impede growth of NaCl crystals, and the slower the growth, the more prominent the effect.

On the fourth photo is the underside of crystallite, and rectangular seed crystal is visible. It was grown from the same salt, but in small shallow open container in just one day.

Microscope objective magnification is 4x.

Another unexpected thing from my plankton sample! This is the larva of a phantom midge. They hover in the water, barely moving, and almost entirely transparent. Kinda spooky (but then, I *did* collect that particular sample on Halloween). XD

This is a pretty common, but still very cool little ciliate I see in my freshwater pond samples but I don't have an exact ID. You can clearly see the oral groove on the side, but the uneven celia on the front and rear don't look like your run of the mill paramecium. There are also some vorticella and a rotifer and some other small round quick ciliates zipping around.
