On day 4, we saw a dirty water sample- and even though the professor had warned us that observation would be difficult, we were all really hyped.
For this, we had to set up the slide in a different way to allow the water to move. We took a separate glass slide and taped it, sandwhiching the water in between.
Going into the observation, I was expecting to see all sorts of tiny organisms swimming around. However, for most of us, the sample turned out to be surprisingly difficult to observe. Many of us couldn't find much at all, despite spending quite a bit of time searching.
The most interesting thing I found was a random black object that I couldn't identify. I spent a while trying to figure out what it was, but it remained a mystery. While my discovery wasn't very exciting, one of my classmates made an incredible find—a tardigrade!
As soon as the tardigrade was spotted, everyone crowded around to observe it. We spent a long time watching it move around and feed on tiny particles in the water. Seeing a living organism behaving naturally under the foldscope was probably the coolest thing I observed during the entire course.
Later, when we saw an image of the tardigradee,it looked quite strange, almost like a tiny wrinkly bear with multiple stubby legs. Despite its funny appearance, tardigrades are actually some of the toughest organisms on Earth. They can survive extreme temperatures, intense radiation, and even the vacuum of space by entering a special dormant state called cryptobiosis.
Watching the tardigrade feed and move around made the microscopic world feel much more alive and real. Even though most of us didn't find much in our own samples, getting to observe a tardigrade up close was an unforgettable experience and a nice way to appreciate what others found, even if we didn't have the same luck. I think something this course has really instilled in all of us is the value of being patient and determined.
