🔬 089 - How can you collect pond water for microscopy? | Microscopy

Pond water is very popular for observing under the microscope. In this video I give you some advice on how to best collect pond water.

🔬 MICROSCOPE RECOMMENDATION
I receive many questions on which microscope one should buy. I recommend the following models for amateur microscopy (Affiliate Links to Amazon):

Right after getting a microscope I discovered your helpful channel and now I'm binging your backlog of videos. Thank you!!

I remember this day... 5 years ago... I was watching this video on 1st May 2019 early morning in my balcony and feeling the aroma of summer breeze... I was in middle school back then... happy and grateful as I look back how far I have come... microscopy is still my favorite hobby ... I have been watching Oliver's channel since it's very beginning... Jan-Feb 2018 I remember...😌 I have refreshed my memories now...❤

this was so helpful, i have an environmental microbiology class this semester and one assignment is to collect pond water but i wasn't sure how to do it properly. Thanks for the tips!

Excellent for high school biology students to view before collecting pond water samples for microorganism study under the microscope. Thank you!

[Mark-ksjj]

Great easy to follow information as usual

From reddit! I'm trying to get into microscopy so I'll stick around. Subbed!

Thank you for the advice. I have been trying to collect a pond specimen for my daughter and we have come up with only some algae but no moving microbes. I will try again. Strange that when I was a kid, I had no problem collecting water with very interesting microscopic life. I even managed to get a hydra in the mix which I spotted with my naked eye.

Thank you a lot for the tips! I will try them for my class at the university

This is my favorite channel ever! I want to be a microbiologist Myself

[DodongoManoof]

Excellent tips. I wonder what I will find in my sample~!

[zagaberoo]

Very helpful; I'll definitely give these a try!

I have a question about the first way to make an enrichment culture: what kind of artificial fertilizer would you recommend? Thank you.

Hi Oliver. Yesterday I visited the Carrizo Plains National Monument on the San Andreas Fault in southern California. Soda Lake is locatedthere, and 99% of the lake is dry now because it's summertime. However, at one end there is a very small pond of water remaining, so I took a sample for microscopy. I thought maybe I would see some new/unusual microorganisms. Well, I was quite surprised. While there were not many microorganisms, I discovered myriad microscopic crystals, like tiny diamonds, suspended in the water. When the lake is dry, it is almost completely white on the surface due to the salts that have concentrated there over eons of time. It turns out the lake has been mined on and off for centuries for these salts, including thenardite (sodium sulfate) and halite (salt). Do you have any experience or comments on finding and seeing microscopic crystals in water samples? I wonder, for example, if all big crystals start as microscopic versions of their larger selves? Many thx.

Your channel is somewhat like a boon for us. Keep it up.

I request you to please make a video on plasmolysis( its in one of your magazine)

What are those
I have caght them

I wonder what's the concentration of microbes in a typical "holy water font" (aspersorium) found in places of worship. I've seen examples with alarmingly high concentrations of algae. Those are touched by lots of people daily, which doesn't seem hygienic, especially in Summer, when the ambient temperature tops over 30 degrees Celsius. I'd be very interested in an experiment involving various techniques of making enrichment cultures from samples of holy water. Have you tried adding a pinch of sugar?

[michaelfishstein]

Any suggestions for finding Nematodes in soil?

[asianwithahoodie]

does scooping the sediment directly from the bottom work too?

[lanasadiella]

I love your channel even though its completely irrelevant to me. Thank you for the videos!

[jose.a.velazquez-mendez]

Hello ! I want You to know that i enjoyed watching your video.

I am getting ready to purchase a microscope, to try to get familiar observing aquarium water microbiology, as well as water from a tiny creek, which sometimes dries out in the dry seasons, in Orsnge County, Ca.

So, your advice is applicable to my situation. Thanks, again.
