The Family in the Wood

Pick up a rotting log sometime. Not a p***y one, not one that crumbles to powder when you lift it. Look for the solid kind, the one that still holds its shape but gives a little when you press your thumb in. There is a world inside it.

If you are lucky, you will find bess beetles. They are big for beetles, shiny and black and deliberate. They do not scatter when you expose them the way most insects do. They pause. They seem, for a moment, to consider you.

What is happening inside that log is something we do not usually expect from beetles. There is a family there. A mother and a father, and if the season is right, larvae curled in chambers of chewed wood, pale and soft, waiting. The adults have already done the difficult task. They chew the rotting wood into a fine, moist pulp and the larvae consume its cellulose fibers and the fungi woven through them. A bess beetle larva cannot manage raw wood on its own. It needs what its parents have already transformed.

Rachel Carson wrote that the more clearly we can focus our attention on the wonders and realities of the universe around us, the less taste we shall have for destruction. I think she would have loved this log. She would have seen past the rot to the industry inside it, to the economy of care that holds the whole small civilization together.

The beetles also speak to each other. They stridulate, rub their wings against their bodies, and the sounds are different depending on who is making them and why. The larvae call to the adults. The adults answer. Fourteen distinct signals, some say. It is a language we are only beginning to hear.

If you press your ear close to the log, you can hear the chewing. It is a small, steady sound. It does not stop.

The older offspring stay too. Adult sons and daughters that have already completed their own metamorphosis remain in the colony, helping to feed the newer larvae and to construct the protective cases where the next generation will transform.

When the time comes to pupate, the larva does not simply curl up and wait. It builds. Working with the adult beside it, it packs chewed wood and frass, digested wood passed through a body and transformed, into a tight case around itself. The material is fibrous and dense, faintly damp, smelling of the log's deep interior. The adult piles debris against the outside until the pupa is sealed in something snug and wrought, a small room made of what the forest has already used and given back.

Mary Oliver would have knelt down. She would have gotten her knees dirty. She would have asked the question she always asked, the one that cuts right through: what is it you plan to do with your one wild and precious life? The bess beetle does not hesitate. It tends the young. It chews the wood. It answers when called. It builds the case around the pupa with its own body and its own labor.

My childhood mentor, Lola would have knelt down beside you. She would have said: what do you notice? She would have waited, really waited, while you looked. She would have asked you what questions were rising up in you, and she would have treated every one of them as worthy. She would have found in this beetle, this brilliantly black, deliberate, shining creature going about its subtle work, something worth honoring. Not because it was rare. Not because it was beautiful in any obvious way. But because it was alive, and doing what it was made to do, and doing it with what can only be called devotion.

That would have been her gift to you. Not the answer. The looking.

🏜️ Canyon Makers in the Making!

Yesterday our young geologists got their hands on one of geology’s biggest mysteries. How did the Grand Canyon form?

Using just a paint tray and sand, students modeled the Spillover Theory: a prehistoric lake called Lake Bidahochi slowly filled with water from the ancestral Colorado River until one day, it spilled over. That spill, repeated and magnified over millions of years, carved one of the most spectacular landscapes on Earth.

And here’s the exciting part — this isn’t just an old idea. In April 2026, USGS scientists published brand-new research in the journal Science confirming that Lake Bidahochi played a direct role in shaping the Grand Canyon and the entire Colorado River system. Our students were modeling cutting-edge geology! 🌊🪨

Science is never finished. There’s always more to discover and sometimes the biggest answers start with a tray of sand and a good question.

Shout out to our SSW geologist Kelly Henry Staab for introducing the Spillover Theory to me during the Covid shutdown and for designing the hands-on experience for our students. 😀

A Living Legend Meets Its Match! 🐟🗿

​Check out this deep-sea celebrity!

My Coelacanth (pronounced see-la-kanth) plushie is taking a well-deserved nap on a bed of actual fossils. It’s a poetic pairing: a "living fossil" resting on the remnants of a world that time forgot.

​The Fish That Fooled the World

​For decades, scientists thought these guys went extinct 66 million years ago along with the dinosaurs. They were known only from stone imprints until a legendary woman named Marjorie Courtenay-Latimer changed history in 1938.

​Marjorie, a young museum curator in South Africa, was rummaging through a fisherman's "pile of junk fish" when she spotted a flash of iridescent blue. Despite the local mortuary refusing to store the "stinky fish" and her boss telling her it was just a common cod, she followed her gut.

​When an expert finally saw her sketches, he said it felt like a "bomb burst in his brain." She had found a ghost! To honor her, the scientific name is officially Latimeria chalumnae.

​Why This Fish is Totally Marvelous:

​Lobed Fins: Those chunky fins have bones structurally similar to our own arms and legs. They’re basically the cousins of the first fish that crawled onto land!

​Electrosensory Snout: They have a "rostral organ" in their nose to detect the electrical impulses of prey in the pitch black of the ocean.

​Late Bloomers: They can live for 100 years and don't even hit "puberty" until they're about 40.

​From a stinky pile of fish in 1938 to a cozy spot on my desk today—long live the Coelacanth! 🌊✨

🪱✨ The worm's MAGIC COLLAR! ✨🪱

Today our young naturalists made one of the best discoveries of the year — the clitellum.

That little raised band toward the front of the worm's body? The kids called it the magic collar the moment they spotted it. And honestly? They're not wrong. The clitellum produces a ring that slides off the worm's body and forms a cocoon — containing eggs, stored s***m, and nutrients for the developing embryos inside. That modest-looking collar builds a tiny, self-contained nursery.

Watching a five-year-old hold a worm still, squint at it, and whisper "I found it!" — that is exactly what science is supposed to feel like.

🌱 For centuries, Europeans thought earthworms were pests. Then Charles Darwin spent 40 years watching them, weighing their castings — and yes, actually listening to them. He played piano near their pots. He had his son blast a bassoon. He shouted at them. The worms ignored all of it — until someone put their pot ON TOP of the piano. Turns out earthworms don't hear sound. They feel vibration. Darwin figured that out in his living room.

That one scientist changed everything. Aristotle had known worms mattered. Cleopatra had protected them by law. Darwin convinced the rest of the world.

Today, so did we.

What’s hiding in diatomaceous earth?

I took a closer look at some diatomaceous earth today using a phone microscope — and honestly, I had to look twice.

That pale, curved, beaded strand isn’t a worm. It’s a chain of diatoms — microscopic single-celled algae that lived millions of years ago. Each little “bead” is actually one individual cell, encased in a tiny shell made of silica glass, called a frustule. When the organism died, that glass shell stayed behind — perfectly preserved.

Diatomaceous earth is essentially a graveyard of these ancient creatures, compressed over geological time and mined from lake and ocean beds. The powder we use in our gardens, our grain storage, even our pool filters — is made entirely of their remains.

What you’re looking at here appears to be a chain-forming diatom — a species that linked its cells together end-to-end while alive, forming long strands like a microscopic pearl necklace. Genera like Aulacoseira commonly grow this way.

And here’s the wild part: this is what kills insects. Those same beautiful glass shells are razor-sharp at the microscopic scale. To us, DE feels like soft powder. To a beetle or a flea, it’s like crawling through shards of broken glass.

Nature is extraordinary — even in a handful of dust. 🌿

🎢 Monday’s Rollercoaster Workshop Recap!

Our students got hands-on with some fundamental physics concepts on Monday — and had a great time doing it.

Potential Energy & Kinetic Energy

Using marble roller coasters, students explored the relationship between potential energy and kinetic energy.

At the top of a hill, the marble has gravitational potential energy. As it rolls down, that energy is converted into kinetic energy — the energy of motion. The higher the start point, the more energy the marble has to carry through the track.

Friction & Surface Materials

Students also looked at friction — a force that acts along the surface of the track and gradually takes energy out of the system. They noticed how the marble behaved differently on different track materials:

Foam tubing: Rougher surface increased friction, causing the marble to slow down more quickly.

Electrical tape joints: Smoother surface meant less resistance, so the marble rolled more freely and maintained speed for longer.

These comparisons helped students see that friction depends on the materials in contact, and directly affects how energy is lost as the marble moves.

Curves, Inertia & Banking

Marbles flying off curves showed students that inertia keeps a moving object going in a straight line unless a force continuously redirects it inward. On a curve, the marble doesn’t need to slow down to turn — it needs a sideways (inward) force to keep changing direction.

The solution? Banking the curve. Every surface pushes back on whatever rests on it — this is the normal force, which acts perpendicular to the surface. On a flat track it points straight up.

When the track is tilted, the normal force tilts too, and part of it now points inward. That inward component provides the centripetal force needed to keep the marble following the curve. Banking also reduces how much friction is needed to keep the marble on the track.

Loop Shape Matters

Students discovered that loop shape had a big impact on performance. Smaller, teardrop-shaped loops — narrower at the top and wider at the bottom — worked best. This shape keeps the radius of curvature small at the top of the loop, where speed is lowest, so less centripetal force is needed to maintain contact with the track.

At the bottom, where the marble is moving fastest, the wider shape smooths out the larger forces acting on the marble, making the transition through the loop more controlled.

The Best Learning Came from Things Going Wrong

Geometry, forces, and a lot of trial and error — all working together. As always, the best learning came when things didn’t quite go to plan first. 🚀

🦋 From Caterpillar to Butterfly —
Our 1st Graders Are LIVING the Magic!
Butterfly Habitats Workshop Recap

This week, our 1st graders became junior entomologists — and it was absolutely incredible! We kicked off our Butterfly Habitats Workshop with a deep dive into the arthropod world, and let's just say… these kids are HOOKED on Arthropods! 🐛

Meet the Live Critters They Observed

🪲 Bess beetles
🐛 Rolly polies
🐜 Millipedes
🦋 Butterflies

Students compared legs, body segments, and features to understand what makes each one an arthropod — and what makes butterflies extra special!

The Pasta Life Cycle Activity 🍝

Then came the hands-on pasta life cycle activity — using different pasta shapes to model each stage of butterfly metamorphosis right on paper plate life cycle wheels. Egg, larva, pupa, adult — they built it, named it, and owned it! ✨

Here's the science that blew their minds: students tracked imaginal disks through each stage of metamorphosis. These specialized clusters of cells are present inside the caterpillar from the very beginning — and they stay organized and intact all the way through the pupal stage. 🧬

Contrary to a common myth, the pupa is not just a bag of dissolved "soup" — the imaginal disks maintain their structure and use the nutrients from surrounding tissue to build wings, antennae, and eyes.

Metamorphosis is an incredibly organized, purposeful process!

⭐ OUR NEW CLASS HEROINE

Maria Sibylla Merian (1647–1717)
Long before butterflies were cool, Maria Sibylla Merian was out there DISCOVERING them. A naturalist, artist, and fearless explorer, she was one of the first scientists to observe and document the full life cycle of insects — at a time when women were rarely allowed in science at all. At age 52, she sailed to Suriname to study tropical insects in the wild and produced stunning illustrated books that changed how the world understood metamorphosis. Our 1st graders think she's pretty amazing — and we agree! 🎨🔬

Live Painted Ladies in the Classroom! 👀

Each class took home live Painted Lady caterpillars in butterfly cages to observe in their own classrooms. They'll watch the chrysalis form — and witness the full emergence of a butterfly with their very own eyes. 🌿
