What Are the Parts of a Pumpkin?
On the Outside
Stem: The wooden handle that connected the pumpkin to its mother vine.Skin (Rind): The tough, waxy orange jacket that protects the pumpkin.Ribs: The bumpy stripes running down the outside from top to bottom.
On the Inside
Flesh: The thick orange wall that people cook into delicious pumpkin pie!Pulp (Strings): The wet, gooey tangles that hold and protect the seeds.Seeds: Smooth white seeds ready to grow into new pumpkin plants next year!
Fun Science Fact: A pumpkin is actually a fruit because it grows from a flower and holds seeds inside!
Plant Growth
The 5 Pumpkin Life Cycle Stages
1
Seed
Rests in warm, moist soil.
2
Sprout
Tiny green leaves push up toward sunlight.
3
Vine & Flower
Long green vines grow big yellow flowers.
4
Green Gourd
A baby green pumpkin starts growing big!
5
Orange Pumpkin
Ripe, sweet, and ready for harvest!
What do pumpkin plants need to grow? Sunlight, fresh water, good soil, and warm air!
Detective Work
Our 4 Pumpkin Lab Steps
Step 1
Feel & Look

Share with Your Buddy
Scientist Talk Time!
Question 1: The Touch Test
How did the skin feel compared to the gooey pulp inside? Use words like smooth, bumpy, sticky, or slimy !

[1] Seed • [2] Sprout • [3] Vine & Flower • [4] Green Gourd • [5] Ripe Pumpkin.
Part 6 Kid-Friendly Model Answer: "A pumpkin plant needs sunlight for energy and warmth, and water to drink through its roots so its vines can grow long and make big pumpkins."
Skip-Counting Connection: If a pair counted 8 piles of 10 seeds, guide them to count: 10, 20, 30, 40, 50, 60, 70, 80! If 3 extra loose seeds remain, the total is 83 seeds.

Measurement Math
How Do We Measure a Round Pumpkin?
1. All the Way Around
Wrap a piece of yarn around the widest belly of your pumpkin. Cut the yarn, then measure it on a ruler!
Circumference (Inches)
2. How Tall?
Stand a ruler straight up next to your pumpkin from the flat bottom to the top shoulder.
Height (Inches)
3. How Heavy?
Place your pumpkin on our classroom balance or digital scale. How many pounds is it?
Weight (Pounds)
Mathematician Tip: Always make a guess (estimate) first before you measure! Estimate → Measure
Water Experiment
The Great Pumpkin Splash: Sink or Float?
Make Your Prediction
Pumpkins are heavy and solid on the outside. When we drop one into a big tub of water, what will happen?
Will it sink to the bottom like a rock, or float on top like a boat?
The Big Surprise!
It floats! Even giant 500-pound pumpkins bob in the water like corks!
Why? Inside the pumpkin is a giant pocket of air! The air acts like a swimming life vest!
Science Secret: Objects with lots of trapped air float on top of water!
History & Story
The Three Sisters: Three Best Friends
Sister Corn
The Tall Pole
Corn stalks grow tall and straight up into the sunshine, giving bean vines a strong pole to climb.
Sister Bean
The Soil Feeder
Bean roots make healthy plant food in the dirt to feed all three sister plants so they stay green.
Sister Squash
The Big Umbrella
Big prickly pumpkin leaves spread across the soil like a giant umbrella to block weeds and keep dirt moist!
Indigenous farmers planted all three seeds together in the same mound of earth so they could help each other grow!

Look closely at the pumpkin in the water tub. Check one:
It SUNK to the bottom
It FLOATED on top like a boat!

Teacher Tips for 2nd Grade:
Yarn Tape Technique: Give each student a 30-inch piece of brightly colored yarn. Show them how to pinch the spot where the yarn loops around, cut with safety scissors, and lay the yarn flat against a standard 12-inch ruler.
Sensory Tub: Fill a clear plastic storage container half-full with lukewarm water. Place a plastic towel underneath to catch splashes when testing the pumpkin.

The Very First Jack-o'-Lantern
Long Ago in Ireland
Hundreds of years ago, people in Ireland did not have pumpkins! Instead, they carved spooky faces into tough white turnips and potatoes to light up dark paths.
Turnips were small, hard to scoop, and smelled funny!
A Brand New Pumpkin!
When Irish families moved to America, they discovered big, bright orange pumpkins growing in harvest fields!
Pumpkins were rounder, bigger, softer, and glowed bright like golden lanterns in the night!
Story Connection: Families brought an old tradition to a new home and found a better fruit!

Cool Things People Make from Gourds!
West Africa
Gourd Shaker (Shekere)
Dried gourds are wrapped in beads. When musicians shake them, they make wonderful joyful rattles!

South America
Warm Tea Cups
Small hollowed gourds are dried smooth and used like cozy teacups to drink warm herbal tea with friends.
All around our planet, people have used gourds for music, delicious snacks, and art!
Super Size
Super Giant Champion Pumpkins!
Heavy as a Car!
Did you know some pumpkins grow so huge that farmers need a crane to lift them? The biggest pumpkin in the world weighed over 2,700 pounds!
That is heavier than a baby elephant!
How Do They Grow So Big?
• They drink up to 100 gallons of water every day!
• Farmers build shade tents so their skin does not crack.
• Farmers pick off baby pumpkins so all the plant food goes to one champion!
You are going to write a step-by-step guide explaining how to grow a giant pumpkin!

The Mystery of the Carved Turnip
A long time ago across the ocean in Ireland, families did not have bright orange pumpkins. When autumn came, people celebrated the harvest by carving faces into hard white turnips and potatoes ! They placed small burning coals or candles inside the turnips to light up dark country roads at night.
Later, when Irish families moved to America, they discovered big, beautiful orange pumpkins growing across farm fields. Pumpkins were much rounder, bigger, and far easier to scoop out than hard turnips. When placed in a window with a candle, the pumpkins glowed with a warm, friendly golden light. Everyone loved carving pumpkins, and that is how the jack-o'-lantern tradition became famous!
Story Questions
