#Watching “Pumpkin Jack” Come to Life in Our Classroom
Every fall, after the excitement of Halloween, our classroom welcomes a very special guest: Pumpkin Jack!
Inspired by Pumpkin Jack, the wonderful story by Will Hubbell, we set our carved pumpkin in a clear container to see what happens as the seasons change. What begins as a bright orange jack-o’-lantern slowly transforms over time — and our children become curious scientists, artists, and storytellers as they observe the process.
Science in Action
Each week, the children check on Pumpkin Jack. At first, they notice small changes — a little shriveling, a darker color, maybe even a few spots of mold. We will talk about what might be happening and why. As weeks go by, the pumpkin softens and sinks, teaching us about decomposition and how nature recycles everything back into the earth.
Through hands-on observation, children begin to understand big scientific ideas:
- How living things break down and return nutrients to the soil
- The role of weather, moisture, and insects in nature’s cycle
- Patience and curiosity as they watch slow changes over time
Language and Art Connections
Pumpkin Jack also inspires storytelling and creativity. The children might draw pictures of how he looks, make predictions about what might happen next, and may even dictate stories about “Jack’s adventures.” These activities encourage descriptive language, sequencing, and observation skills — all while making science feel magical.
A Lesson in Renewal
By springtime, something amazing happens — new green sprouts begin to appear where Pumpkin Jack once sat. The children are thrilled to see that Jack’s life continues in a new form! Together we plant the seedlings in our garden and talk about how the life cycle begins again.
Why We Love This Project
Watching Pumpkin Jack disintegrate over the school year connects children deeply to nature and helps them see the world as a living system full of wonder. It’s messy, beautiful, and full of discovery — just like early learning itself.
