A mentor once told me that the heart of STEM isn’t just about science, technology, engineering, or math—it’s about inquiry. It’s about process. It’s about curiosity.
In other words, it’s not about having all the answers—it’s about being deeply invested in the questions. And what better classroom for this kind of thinking than the world of play?
When I watch my children in a forest, I see the essence of STEM at work: they test the weight of branches, mix leaves and mud, and build forts that collapse and get rebuilt, better each time. They’re not following instructions—they’re experimenting, problem-solving, iterating. That’s real learning in action.
Contrast that with a typical playground: up the ladder, down the slide, move on. These are valuable structures, no doubt, but the format is fixed—the outcomes predetermined. The space has already decided how children will play.
That’s the fundamental difference between structured and open-ended environments. One delivers predictable results. The other invites experimentation and discovery.
So if we know that STEM learning thrives on curiosity and creativity, why don’t we design our play spaces the same way?
Designing for the Process, Not the Product
Too often, play environments are goal-oriented. Climb to the top. Finish the maze. Win the race.
But play, at its core, isn’t about finishing—it’s about exploring. It’s as much about whimsy and joy as it is about scraped knees and learning to navigate discomfort. It’s about getting lost and finding your way again.
That spirit is exactly what the best STEM environments cultivate:
- Trial and error (failing forward)
- Multiple solutions (more than one way to engage)
- Ongoing discovery (play that evolves over time)
One of my favorite real-world examples of this kind of thinking is The Outpost and Field Station at Presidio Tunnel Tops in San Francisco. Designed by James Corner Field Operations in collaboration with Earthscape and The Exploratorium, these indoor and outdoor spaces are driven by inquiry, not instruction. They’re places to poke, dig, pour, investigate—and learn by doing.
The goal wasn’t to create a flashy exhibit. It was to simulate the joy of discovering an ecosystem—without the environmental toll of thousands of feet trampling a fragile natural space. The result? A purpose-built environment that’s just as satisfying to explore as the “real thing.”
Imagine if all play spaces worked this way.
Letting Curiosity Lead
A few weeks ago, on our walk to school, my son spotted animal tracks in the snow. He followed them across yards and sidewalks, narrating theories about what made them and where they were headed.
He wasn’t just observing—he was investigating.
That’s the power of curiosity. And children don’t need help being curious—they just need environments that let curiosity lead.
Of course, structured learning has its place. Foundational skills in literacy, math, and reasoning are built through guidance and repetition. But discovery-based learning—especially through play—nurtures executive function, builds resilience, and fosters a genuine love of asking “what if?”
The same balance should exist in how we design play spaces.
Traditional playground elements like swings or slides offer timeless value. But do we also make space for exploration, invention, and messy problem-solving? Do we offer places where kids can:
- Try different ways of climbing, building, and balancing?
- Move, shift, and shape their environment?
- Test ideas and change course mid-play?
This mindset is thriving in many maker spaces, science centers, and some adventure playgrounds—but what about the schoolyard? The corner park? The neighborhood plaza?
Where STEM Meets Imagination
Too often, STEM and the arts are treated as separate spheres—logic vs. creativity, precision vs. emotion. But in reality, the most meaningful discoveries often happen at the intersection of the two.
Artists and scientists share a common toolkit:
- Observation—noticing patterns, asking questions
- Iteration—experimenting, refining, reworking
- Imagination—picturing what doesn’t yet exist
That’s the same process I follow in my own design practice. Each project—especially the playful, sculptural ones—goes through dozens of iterations. I sketch, rethink, adjust. Some ideas lean sculptural, some more natural, others interactive. A few seemed brilliant until they defied physics. But that’s the nature of inquiry. You try. You learn. You build something better.
That’s what a STEM-infused play space can offer, too—not a fixed route or single solution, but an invitation to engage with the world like both an engineer and an artist.
Toward the Future of Play
Designing great play spaces is about more than safety standards and aesthetics. It’s about shaping environments that ignite both curiosity and creativity. That means making room for experimentation—not just execution.
- What if more playgrounds felt like ecosystems?
- What if kids could invent new climbing routes every week?
- What if water, sand, sound, and light were tools for investigation—not just background features?
The heart of STEM in play isn’t a math quiz or a robotic arm. It’s a mud pie. A set of tracks in the snow. A fort that falls down and gets rebuilt, better and braver than before.
At Mischief & Wilde, we believe that’s where the future of play is headed—toward spaces that don’t just entertain but engage. Spaces that inspire children to ask big questions, and give them the tools to find their own answers.
Let’s build spaces where discovery leads the way.
