Miscellaneous Pond Creatures

A video taken through my foldscope of what appears to be a sort of worm floating through the water, and moving through a piece of pond matter. The sample was obtained by taking water from the Baxter pond at Caltech, around 7PM on April 11th, 2019. From the video captured (and from where this still…

Picture of Green Algae from Pond Water

This is a picture of pond water under a foldscope. The water is from the Caltech turtle pond. It was obtained on 4/11/19 at 6:40PM. It was fished from the pond. Green algae can be seen in the picture. The domain of the organism in the image (green algae) is eukaryote. I know this because…

Little fella in Turtle Pond at Caltech

Clip of water from Turtle Pond searching for organisms around algae. Seemed to have found one go by and turn around back through. Seems to be the same organism. Given that the magnification was 140x, the organism was around ~20 micrometers long. Sample obtained 4/11/2019 from the Turtle Ponds at Caltech by using a cup…

Turtle Pond Sample

a.) The image above was taken when observing a droplet sample of pond water through the foldscope. There are droplets of water and a green piece of matter in the center of the picture, as well as smaller transparent pieces of matter surrounding it. The pieces of matter appear to be plant-based; they were not…

Baxter Pond Algae

This is a sample of plant matter taken from the pond in front of Baxter at 4:00 PM on 4/18/2019 and observed through the foldoscope microscope. The original sample was green water droplets, and the sample in the image is small green floating plant-like particulates. This sample was taken by scooping a small sample of…

is this water or is this algae

In this image, we can see an image of what is supposed to be algae from the turtle pond. The black spots were the parts that were actually swimming around when I looked through the foldscope. This sample was obtained from the turtle pond on April 18th, 2019 at approximately 4pm with a plastic cup…

Turtle Pond Specimen

In this photo can be seen algae from the turtle pond at the California Institute of Technology. The specimen was taken in the late afternoon using a cup and was used to demonstrate the creation of a “wet sample”. In the image, a small specimen of algae can be seen at the bottom of the…

baxter muck

This picture was taken of some mud and water and possibly algae. The sample was taken at around 4:30pm, April 18th, 2019 from the surface of the pond outside of Baxter Lecture Hall. The sample was obtained by scooping some mud off the surface with a clean lid from a plastic cup from Chandler. Since…

Turtle Pond Algae

Image description: This is a photo taken with iPhone 6s and a foldscope of a wet sample obtained from the turtle pond on California Institute of Technology campus. Water from the pond were obtained at about 6:00 pm on April 11st, 2019 and stored in a plastic cup until the photo was taken at about…

Green Onion Tissue

This is an image of the epidermal layer of a green onion from Caltech’s open kitchen, taken 4/18/19 at 5PM. The sample was obtained by cutting and removing the thin, membrane-like layer between the thicker layers of the green onion. The layer was placed onto a slide with some water, and observed using the Foldscope….

algae sample for bi001 (Caltech)

This image is taken of a sample obtained from the pond outside Baxter Lecture Hall in Caltech on Thursday, April 11, 2019. The TA’s scooped out the pond water and we dropped the water onto the glass to put into the foldscope. In my image, there is some algae and a small worm. The algae…

Algae from Caltech Turtle Pond under scattered and direct light exposures

The images show an algae structure, observed in a water sample from Caltech’s on-campus turtle pond, under direct and scattered light (generated using Foldscope light equipment). The sample was obtained around 6:30 pm local time (Pasadena, CA) on April 11th, 2019 from the Caltech turtle pond using a cylindrical container. Green algae is a member…

Algae drifting around an air bubble

This video is a picture of an algae (small green dot near the bottom left corner) slowly drifting through the water. There are also two air bubbles in the water, one on the top of the video and another on the bottom left. The algae is slowly pushing through the water moving further down while…

Fragment of Insect Wing

This sample was collected from the Turtle Pond on Caltech campus on a sunny Wednesday afternoon this past week. One of the more interesting things that I spotted was what I believe to be the fragment of an insect wing, visible in the lower portion of the view on the ‘scope. Insects are apart of…

Paramecium from Turtle Pond Sample

A video of a paramecium moving in a sample from the turtle pond. The sample was obtained by ‘scooping’ up water at roughly 6:30 pm on 4/11/2019 from the Caltech turtle pond. a) Paramecium: domain is Eukaryote. We can know because the shape and size of the organism match well with the description of a…

Paramecium in Turtle Pond

In this video, a rather large paramecium can be seen moving across the screen in pond water. This particular sample of pond water was obtained at approximately 6:30 pm on 4/11 in the turtle pond at Caltech. The sample was captured by drawing water from the pond and placing it in a large test tube…

Turtle Pond Water Microscopy

Video examining pond water searching for organisms around algae. One likely organism observed as it seems to be moving by its own power not that of the flow of the water. Sample obtained 4/11/2019 6pm from the Turtle Ponds at Caltech using a cup. Based on the reported magnification of 140X and a scale placed…

Plant By-Product in Pasadena pond

This specimen contains plant by-product likely from algae or some other organism next to a bubble. The sample raises questions about exactly what organism created it, what the different areas of coloration are and what the actual composition of the substance is. This can probably be better studied by taking a sample and doing spectroscopy…

Bi1 Foldscope- Camila B

These are pictures of a water sample from Baxter pond obtained at 4 PM on 4/17/2019. I obtained the sampe by taking a sample of water from the pond, then placing it on a Foldscope slide. The pictures show Amoeba swimming around. I wonder what specific species this organism is and how they are swimming….

Microscopic Matter in Pond Water

https://videopress.com/v/52Mtw9df The video shows what appears to be pollen and other microscopic entities in pond water. The sample was obtained at about 6:20 PM on 4/10/19 from the top tier of Turtle Pond at Caltech, Pasadena, CA. The magnification is 140x, which means that the pollen is on the order of about 10 microns. #caltechbi

A picture of the sample taken during Bi1 recitation

The picture shows a large body - probably a rock, surrounded by some moving organisms. The sample was provided during recitation, the TA said it is from the Turtle pond. The original picture makes the organism in the center to have the size of about 0.5cm x 0.2 cm. The foldscope magnification is 140x, so...
