In the STEAM Spotlight
Cardboard City
Get ready to design, build, and explore in Cardboard City—a hands-on engineering adventure where kids use real cardboard tools to create an immersive, crawl-through city of their own! Throughout the week, children collaborate to cut, color, decorate, and even remodel their cardboard structures, transforming recycled materials into roads, buildings, bridges, and more. This open-ended STEAM activity encourages problem-solving, teamwork, creativity, and spatial awareness. Whether your child loves construction, design, or imaginative play, Cardboard City is a perfect blend of art, architecture, and kid-powered innovation.
In Cardboard City, children use donated cardboard boxes to create an expansive, interactive city filled with tunnels, rooms, and creative designs they can crawl through and color. As the week progresses, more rooms and tunnels are added, making the city grow and evolve based on the children’s ideas and teamwork. This dynamic activity encourages fine motor skills, spatial reasoning, and imaginative play, while teaching concepts of urban planning and construction using eco-friendly materials.
In the weeks leading up to the activity, families donate cardboard boxes of all sizes to help fuel the build. As the week unfolds, new tunnels, rooms, and interactive spaces are added daily, allowing the city to evolve alongside the children's ideas. Kids are encouraged to revisit and redesign different parts of the city, building collaboration and iteration into the experience. By the end of the week, Cardboard City becomes a vibrant, child-made world full of creativity and connection.

Exploring STEAM Stations
The Three Little Pigs STEAM Adventure
We explored the classic tale of The Three Little Pigs to learn about building strong and safe houses. Through hands-on building and a little pretend wolf, the children discovered how different materials affect a structure’s strength.
First, we built the hay house using soft, golden hay gathered by the teacher and the kids. The hay was light and fluffy, easy to stack but very loose, so it didn’t hold together tightly. When the big bad wolf came, we turned on the hairdryer, and the kids squealed and laughed with delight as the hay blew everywhere in a hilarious fluffy storm.
Next, we carefully constructed the stick house with wooden sticks, using playdough as mortar to hold the pieces together. The sticks made the house a bit stronger and more solid than hay, but still not very sturdy. When the wolf tried to blow it down again with the hairdryer, the kids responded with lots of playful howling and giggling as some sticks fell while others stayed in place.
Finally, we built the stone house using heavy stones stacked tightly together. This house was solid and steady, and no matter how hard the hairdryer blew, it didn’t move at all. The children clapped excitedly when the wolf couldn’t break down the stone house, proud to see how strong and safe it was. Through this activity, the kids learned that the materials and how a building is put together affect how strong and safe it can be. It was a hands-on way to discover important ideas about structure, stability, and protection.
3 Little Pigs Building Challenge
After our storytelling, the kids donned their smocks and gathered around the table, each with a cup of shaving cream and a pile of sticks. Their mission? To build a house so strong that no wolf could blow it down, protecting their tiny critters inside. With sticky hands and bright eyes, they experimented with shapes and designs, thinking hard about what would keep their homes safe. The room buzzed with excitement and creativity as the little builders brought their ideas to life—turning a favorite story into an unforgettable STEAM adventure.
Poke Bin Building Challenge
The poke bin includes soft, colorful sections of pool noodles and plastic toothpicks that children can connect to build various shapes and structures. Kids carefully insert the toothpicks into the noodles to create towers, bridges, or any design their imagination leads them to. This activity encourages fine motor development and spatial reasoning as they figure out how pieces fit together and balance. The lightweight materials make it easy to experiment and rebuild, supporting open-ended play and hands-on exploration.
3D House Painting
Print out the house template on sturdy cardstock and assemble it using tape to create a 3D paper house. Older children can practice their cutting and assembly skills by completing the project themselves, while younger children may need some adult assistance. Kids can personalize their houses by spraying them with vibrant liquid watercolors or painting the exterior with regular paint. This hands-on art and engineering activity encourages creativity, fine motor skills, and color exploration.

Little Builders, Exploring Tools
Inside the classroom, children used plastic building tools—like kid-sized hammers, screwdrivers, wrenches, and saws—to design and build their own creative structures. From pretend repairs on shelves to constructing imaginary walls and bridges, kids moved around the room working together, using their tools with focus and enthusiasm. This hands-on play encouraged teamwork, fine motor development, and early engineering skills, all through active exploration. The classroom buzzed with imagination as students proudly “fixed” and “built” everything in sight, taking ownership of their learning environment.
Once their indoor work was complete, we brought the tools outside for a special renovation mission on the playground. Children used their tools to “repair” play equipment, “reinforce” fences, and even “install” new parts using loose parts and natural materials they found. It was a joyful blend of role-play, construction, and outdoor exploration. By taking their work beyond the classroom, students practiced problem-solving and collaboration in a larger, more open-ended space. This tool-based activity gave them a sense of responsibility, creativity, and confidence in both indoor and outdoor learning environments.
