A Farm School Lesson in Science, Math, Nutrition, and History
When pumpkin season rolls around, we love showing kids how even the “scraps” of a harvest can become something nourishing and delicious. This simple activity turns sticky handfuls of seeds into a crunchy fall snack — while sneaking in lessons about science, math, nutrition, and history along the way. 🌾
Choosing the Right Pumpkins
Not all pumpkins are created the same when it comes to seeds or puree! Large carving pumpkins (like the kind we decorate for Halloween) have big seeds and they can be a little tougher in general. BUT this is what we used today and most of our kiddos seemed to enjoy them. If you’d like something more tender you can use pie pumpkins such as Sugar Pie, Baby Bear, or New England Pie. Their seeds are tender and crisp beautifully in the oven.
If you want to grow your own next year, try a hulless variety (They naturally don’t have an outside to their seed) like Kakai or Lady Godiva — their shell-free green pepitas roast up perfectly every time.
🌱🍂 COOKING & DIRECTIONS
1️⃣ PREHEAT
Set oven to 325°F.
Warm air is the start of the science! This moderate heat helps water inside the seeds evaporate slowly, giving them time to dry and crisp evenly without burning.
👉 Did You Know? Roasting at too high a temperature can make the outside brown before the inside has finished drying.
2️⃣ SCOOP & RINSE
Scoop out the seeds, remove the stringy pulp, and rinse in a colander.
This part is messy — and fun! Rinsing separates the seeds from the sticky pumpkin fibers.
👉 Kids ask the BEST questions! Why do we need to clean the seeds?
Why it matters: That slimy coating holds extra moisture and sugars that can make seeds steam instead of roast. Removing it helps them toast more evenly. AND most of the kid loved the slimy consistency in their hands.
3️⃣ PAT & DRY
We skimmed them from the water with a slotted spoon — a surprising fine-motor workout! Each time the spoon went back in, the floating seeds slipped away, turning it into a playful “who can scoop the most?” challenge.
Pat with a towel and let air dry for 24 hours.
Patting and air-drying is the secret to crunch! The drier the seeds, the faster they roast and the crispier they get.
👉 Science Link: Water must evaporate before the seeds can brown. If they start too wet, they’ll soften instead of snap.
4️⃣ SEASON & TOSS
Coat seeds evenly to help heat transfer across the shell. The oil creates that irresistible golden sheen, and the salt adds flavor while pulling a little more moisture to the surface.
🌿 Flavor Twists — Choose Your Favorite!
Start with the Base Mix (for every 1 cup of seeds):
1 teaspoon oil (olive, avocado, butter, or coconut)
½ teaspoon salt
Then pick a flavor idea below — or invent your own!
🍂 Ranch
Add:
¼ teaspoon garlic powder
¼ teaspoon dried dill
A pinch of onion powder
Smells like ranch dressing — crispy and savory!
🍊 Chili Lime
Add:
¼ teaspoon chili powder
Zest (grated peel) from ½ a lime
After baking, squeeze a little fresh lime juice over the warm seeds for a tangy, zippy finish.
🍬 Cinnamon Sugar
Add:
½ teaspoon cinnamon before roasting
After baking, while seeds are still warm, sprinkle with 1 teaspoon sugar and toss to coat for a sweet, cozy crunch.
👉 Try This:
Let kids smell each spice before adding it and guess which one will smell the strongest after roasting — then taste and see who was right!
🧡 Create Your OWN Flavor!
Mix and match your favorite seasonings to make a brand-new recipe.
When you find something you like give it a fun name and write your OWN recipe.
(TIP: Mommas I know it’s hard but let them use their imagination, get messy, and be creative!)

5️⃣ SPREAD OUT
Spread in a single layer on a parchment-lined baking sheet.
Crowded seeds trap steam — spacing gives each one room to crisp on all sides.
6️⃣ ROAST
Bake 20-25 minutes, stirring halfway through.
Gentle, even roasting keeps seeds from burning. Stirring moves cooler seeds from edges to center for even color and crunch.
👉 Observation Idea: Watch for color change and listen for quiet popping sounds — that’s steam escaping! its funny the first class we heard the snap crackle pop the second it was totally silent.
7️⃣ COOL & CRUNCH
Remove when golden and toasty. Cool completely before eating.
Seeds continue to crisp as they cool — the final bit of moisture leaves, and the shell hardens.
👉 Science in Action: As hot air meets cool air, the seed structure sets. Test one warm vs. one cooled — which is crunchier?
🔬 SCIENCE LESSONS
🌱 Discovering the Science of Seeds
Every seed carries everything needed to grow a whole new plant. Before roasting, we pause to appreciate that each one could have become next year’s pumpkin!
Try This: Save 3–5 raw seeds to plant in spring. (If the pumpkin came from a mix of varieties, your new pumpkins might surprise you — you never know what colors or shapes you’ll get!)
👉 Talk About It:
What does a seed need to grow?
How do warmth & water start germination?
Why won’t roasted seeds sprout afterward?
🌻 Roasting in Action: Kitchen Science
When we roast seeds, heat and moisture work together in a little kitchen science experiment.
The water inside turns to steam and pushes against the shell — that’s what makes it crisp and toasty!
💡 Did You Know?
Fresh pumpkin seeds can be nearly half water inside.
As they roast, that water evaporates — the same process that dries puddles after rain.
The pops and sizzles you hear? That’s steam escaping!
🧪 Observing the Science (Ages 3–13)
👧 Ages 3–6:
Use your senses like a scientist!
👀 Do they darken or puff up?
👂 Hear any pops or cracks?
👃 Smell toasty or nutty?
✋ Feel smooth, warm, or crunchy after cooling?
👩🔬 Ages 6–13:
Weigh or measure a cup of seeds before roasting.
Roast, cool, and weigh again.
Discuss what changed — did they get lighter? Why? (Hint: water left!)
Older kids can calculate the percentage of water lost.
💧 Why Pumpkin Seeds Float
When rinsing, notice how pumpkin seeds float — they’re less dense than water!
Tiny air pockets inside their shells act like life jackets, while heavier pumpkin pulp sinks.
🌱 Every Seed Is Unique:
Thick and mature = extra crunchy when roasted.
Thin or flat = younger, less developed.
Curved or misshapen = nature’s reminder that no two seeds are alike.
➗ MATH CONNECTIONS
🧮 Pumpkin Seed Geometry
👧 Ages 4–6:
Count handfuls or scoops together.
Arrange seeds in rows and columns (like a grid) and count by 2s or 5s.
👩🔬 Ages 7–13:
Measure the pan’s length and width to find its area (L × W).
Estimate how many seeds fit if each takes about ½ inch of space.
Compare your prediction to the real number and find the difference.
🧂 Ratios & Measurement in Cooking
Cooking is one of the best ways to make math real!
For every 1 cup of seeds, use 1 teaspoon oil and ½ teaspoon salt.
Talk about fractions and ratios while measuring.
Count seeds, track oven time, or graph color changes.
Little hands can scoop and stir, while older ones calculate and record.
🥕 NUTRITION ON THE FARM
Pumpkin seeds (pepitas) are packed with goodness straight from nature:
🌾 Protein for strong muscles
⚡ Magnesium & zinc for steady energy and focus
💚 Healthy fats for the heart and brain
🌿 Fiber for healthy digestion
But nutrition isn’t just about what’s in the food — it’s also about how we prepare it.
When we roast pumpkin seeds ourselves, we:
Skip preservatives and extra salt that often hide in packaged snacks.
Choose real ingredients — just seeds, oil, and simple seasonings.
Preserve nutrients that can be lost in commercial processing.
Model self-sufficiency — showing kids how easy and satisfying it is to make something from the garden.
👉 Why We Bother:
Making it ourselves connects us to the harvest. We waste less, eat better, and remind our kids that good food doesn’t need packaging — just curiosity, time, and care.
Homemade snacks like these give our bodies real fuel — nothing wasted, everything gained.
📜 HISTORY & GEOGRAPHY CONNECTIONS
🌎 How the Pumpkin Traveled the World
A Story of Seeds, Sailors, and Shared Harvests LINK FOR PRINTABLE VERSION
Long ago — before there were grocery stores or airplanes — people had to grow everything they ate. In the warm valleys of North and Central America, pumpkins thrived. Their vines crept across the ground, and their golden fruits ripened in the sun. Families roasted the seeds over campfires, cooked the flesh in stews, and even dried thin pumpkin strips to eat during the winter. Every part was precious. Nothing was wasted. 🌾
When explorers and sailors began sailing across the oceans in the 1400s and 1500s, they carried more than maps and courage — they carried curiosity. As they met new people in faraway lands, they discovered foods they’d never seen before: corn, tomatoes, cocoa, peppers… and pumpkins!
The sailors packed seeds carefully into pouches and barrels, knowing they were carrying a living gift. Across stormy seas the seeds sailed, tucked away in ships that smelled of salt, spice, and adventure.
When they reached Europe, farmers planted them in their own soil — and to everyone’s delight, the seeds sprouted! Pumpkins began growing in gardens in France, Italy, and Spain. They looked a little different in each place, but they all carried the same sweetness and strength of the American soil they came from.
As trade continued, the seeds traveled farther — to Africa, Asia, and beyond — following the winds of the Columbian Exchange, a great swapping of plants, animals, and ideas that forever changed how people ate. In some countries, pumpkins were turned into soups and curries; in others, into sweets and breads. The pumpkin had become a world traveler — connecting people through flavor, curiosity, and gratitude.
🌍 Farm School Reflection
Just like those early farmers, we save seeds from our pumpkins, dry them carefully, and plant them again in the spring. Each seed tells a story of where it’s been — and where it might grow next.
👉 Try This: On a map, mark where pumpkins started (North America) and trace their journey across the oceans. Talk about what foods we might share if we could send a care package to another country. What would represent “home” to you?
💬 FARM REFLECTIONS & SUSTAINABILITY
