Building STEAM: Equity In Practice
Discovery Science · Week 8
Carnival science — pinwheels and listening well
Students told us what they wanted to learn — and we worked on a carnival‑themed build every student could finish.

“If you could learn anything about science, what would you want to learn?”
— The question that opened the session
We started by handing the question back to students: if you had the chance to learn anything about science, what would you want to learn?
The answers came fast. Slime, over and over. One student wanted to make action figures out of pipe cleaners and was asked whether he might be interested in seeing action figures — Dummy 13s — made on a 3D printer. One student wanted to know what makes grass grow.
Then we asked about their favorite lessons from the summer. The clear winners were Water and Wonder and the water filter session — the days with the most stations, the most hands‑on materials, and the most room to test their own guesses.
That conversation was the real work of the opening. It functioned as an interest assessment: a direct read on what students are curious about and what formats have landed.
From there we moved into the carnival theme for the week, talked about favorite carnival prizes, and used that as the way into the build.
Why this lesson
The problem we’re trying to solve
In many learning spaces, students don’t get many chances to imagine and shape their own worlds. They are often asked to sit, listen, and follow instructions, rather than invited to help create and care for the places where they live, play, and grow.
That includes the curriculum itself. Students are rarely asked what they want to learn, and even more rarely does the answer change anything. Plans are made in advance by adults and delivered regardless of what’s happening in the room.
This session was designed the other way around. The original plan for Week 8 was a Ferris wheel versus prize wheel build. After watching students struggle with fine motor demands in the catapult and paper circuit sessions, we replaced it. Not because the students weren’t capable, but because the build was making the wrong thing hard.
So we swapped in pinwheels — same carnival theme, same physics of rotation and applied force, a build students could actually complete and own from start to finish.

Lesson snapshot
Carnival pinwheels
Students design and build their own pinwheels, learning how moving air pushes against angled surfaces to create rotation — and practicing a full build they could complete independently.
Big idea
Force applied to angled surfaces produces rotation — the physics behind carnival pinwheels.
Time
About 60 minutes, including the opening interest conversation.
Materials
Card stock, a cardboard square template, bottle cap, pipe cleaner, and plastic straw
In practice
What we did together
After the carnival prize conversation, students moved into making their own pinwheels.
Each student chose their own cardstock. Using cardboard square templates we provided, they traced and cut out their own square — their choice of color, their own tracing, their own cut.
From there we worked through the folds step by step: diagonal folds corner to corner across the center, then cuts along those fold lines stopping short of the middle.
We punched a hole in the center of each square. Then, before any gluing, we marked the next fold with an X on each corner that needed to come in — the way a woodworker marks stock before a cut, so you know what goes where before you commit.
To seal the pinwheel and create a clean center, students traced a bottle cap onto cardstock to make a small circle, and we punched a hole through its middle. That circle held the glued corners down and created a channel for the axle.
Instead of sharp pins, students used pipe cleaners as their axle — threaded through the center circle, through the pinwheel, and secured to a straw. Every student left with a working pinwheel they had cut, folded, marked, glued, and assembled themselves.
What we noticed and why it matters
Across the catapult build and the paper circuit build, a pattern showed up: students were losing the science to the fine motor work. Rubber bands wouldn’t stay wrapped. Copper tape tore. LED legs slipped. Students who understood the concept perfectly well were spending their hour fighting materials.
The pinwheel build kept the same underlying physics — force applied to angled surfaces produces rotation — while giving students a set of steps they could execute independently. The result was that everyone finished, and everyone left with something they made.
The opening conversation was just as valuable. Asking students what they want to learn produced usable data: slime, grass growth, 3D‑printed action figures, and the multi‑station format of Water and Wonder. We’re planning from that list, not around it.
What might change in Oakland if students were regularly asked what they want to learn — and the answer actually changed the curriculum?
This session shows what it looks like to let student experience drive curriculum design.
We opened with an interest assessment because we wanted the next arc to come from students rather than from us.
If this vision resonates with you, we invite you to help us create more spaces where student voice and joyful inquiry guide the work.
