What happens when your student discovers an unnamed species of algae: A middle school teacher’s experience
The bell had just rung for 4th period on a rainy May afternoon, and half my 8th grade science class was already packing up their binders early, testing week having left everyone too fried to care much about freshwater algae ID. Mia, who sat in the back row and always left smooth river rocks on my desk for the classroom terrarium, had her head pressed so close to the eyepiece of our 15-year-old classroom microscope that her bangs were sticking to the lens. She waved me over, quiet like she always was, and said, “None of these look right. Is this supposed to be here?”
I’d already had seven kids that week misidentify common desmids because they mixed up ridge patterns, so I trundled over ready to walk through the ID checklist step by step. I leaned in, twisted the fine focus knob, and paused. What Mia had found was a cluster of tiny spherical algae, each lined with fine bristle-like projections that stretched twice as long as any example on our ID sheet. I’d been teaching middle school science for 12 years, and collected dozens of samples from the creek behind our school, and I’d never seen anything like it. I snapped three photos with my beat-up iPhone, jotted down the location (100 yards upstream from the footbridge behind the soccer field), water temperature (14 Celsius, which we’d checked that morning), and uploaded it to the state’s citizen science project portal like we did for all out-of-the-ordinary finds. I didn’t think about it again until I was grading finals in mid-June, when an email popped up from the lead researcher at the state university.
She said that sample was something special. It matched a partial observation from a glacial lake 200 miles north made three years prior, but no one had collected a full enough sample to study, let alone formally describe. It was almost certainly a species no biologist had ever officially named. They wanted Mia to come to the lab that summer, help them process the sample, walk through the DNA extraction steps, and if it all checked out, she’d be listed as a co-discoverer.
I called Mia’s mom that night, and she was quiet for a full minute before she said, “Mia has always said she’s bad at science. She does fine on homework, but her standardized test scores are always below grade level, so she’s convinced she just doesn’t have the brain for it.” That line has stuck with me for months now. So many parents and even fellow teachers I work with ask why I waste class time on open-ended projects like this instead of extra test prep. They say it’s nice for fun, but it doesn’t help kids get into advanced high school science classes or score well on required exams.
What this experience showed me, though, is that most of our standard science education is set up to only reward kids who can pick the right pre-existing answer. If your kid is curious about things that don’t have a pre-printed box to check on a multiple choice question, that curiosity often gets pushed to the side. This isn’t just about algae, either. In the last five years, I’ve had kids find new populations of rare endangered plants on school grounds, document a range extension for a native bee that no one knew lived this far south, all from casual, low-effort class projects.
The best part is you don’t need any fancy gear or a science degree to make this work for your kids or students. The citizen science project we used is free, they mail empty sample bottles and print ID sheets for free if you’re a K-12 teacher. If you’re a parent who wants to try something similar on a weekend hike, you can just download iNaturalist for free, and every observation you upload goes directly to real researchers working on species distribution and conservation. The biggest shift I’ve made in my classroom after Mia’s find is that I stopped defaulting to “you must have misidentified it” when a kid says their find doesn’t match the guide. Now I keep a shared public Google folder where any kid can upload a photo and notes of their unusual find in 30 seconds. It takes me two minutes a day to keep it organized, no extra prep, no extra cost. For parents, that just means instead of pulling out your phone to look up the immediate answer, you say “let’s write down where we found this and take a picture, then send it to the project to check.” That’s it, it’s that small of an adjustment.
A lot of people hear “discovering a new species” and picture famous explorers trekking through the Amazon. But most of the species that haven’t been named yet are tiny: algae, fungi, small beetles, tiny crustaceans that live in shallow streams. There are thousands of them just waiting for someone to notice they don’t match the existing descriptions. Last week, Mia came back to visit after her first semester of high school and brought me a photo of her standing next to the lab’s DNA sequencing machine. They’re still running tests, so it might be another year before they confirm it’s a new species, and even then, there’s pages of paperwork to get it officially added to the global registry. She still wants to name it after Cedar Creek, the little creek behind our school that everyone just uses as a place to skip rocks after lunch.
I still get emails from parents asking if we can shift more class time to test prep instead of these field projects. I tell them what I saw: Mia, who used to never raise her hand in science class, now gives 15 minute presentations to the local elementary school science club about her algae. She says she wants to study freshwater biology in college now. That’s not something a multiple choice practice test would have pulled out of her. It’s still not a done deal. The sample might end up being a weird variation of a known species, after all. Even if it doesn’t, Mia already knows she’s capable of noticing something no one else has. That’s more than any test score can give her.
