Pumpkin Science Experiment Classics and More!
“I can smell autumn dancing in the breeze. The sweet chill of pumpkin, and crisp sunburnt leaves.” – Ann Drake, Author
It’s Fall and that means it’s pumpkin season! That time of year when we are surrounded by all things pumpkin. We eat them, drink them, carve them, and decorate with them. Many of us look forward to the abundance of pumpkin spiced options — employing those lattes, cookies, breads, pie, and delicious smelling candles to help us get into that cozy feeling of the season.
Yet there truly is more to a pumpkin than meets the pie. At Stratford our young students are immersed in engaging science experiments centered all around pumpkins because pumpkins just so happen to be the perfect vegetable to get children excited about the wonders of science and nature. So this year, go out and get your happiness-inducing pumpkins and whimsical looking gourds, and prepare to explore the fascinating science of a pumpkin with your child.
Shopping for Pumpkins
We all love to look for the “perfect” pumpkin whether that means round and robust, tall and cylindrical, or the one that has a personality all its own. Take your child with you to the pumpkin patch or the store to pick out their favorite pumpkins and gourds. If you have options, select a colorful variety of shapes and sizes. Get a big one, a little one, and liven it up with some gourds of varying colors and textures.
Exploring Your Pumpkins
Once you get your pumpkin haul home, lay out your pumpkins on a table and have your child get out their lab coat (an old t-shirt or apron will do), measuring tape, and magnifying glass. It’s time to start our science exploration.
Starting with a standard looking pumpkin, let’s talk about the differences that we can see on the outside first.
• What does the pumpkin look and feel like?
• How would your child describe the texture of the shell of their pumpkin? Is it bumpy or is it smooth?
• Encourage your child to use their senses and write down all of the things they can see, hear, feel, and smell.
• Shake up the pumpkin. Does it make a sound?
• Get a measuring tape and have your child measure the height and circumference of their pumpkin.
• Does the pumpkin have a stem? What color is the stem? Is the texture of the stem the same as the pumpkin’s shell?
• Let’s compare the pumpkin to one of the other gourds. What color is the gourd? Is the gourd texture and shape similar or different from the pumpkin?
Looking at all of these details and answering all of these questions is called “scientific observation” and it is one of the primary ways that scientists research their subject. Your child is now an official Squash Scientist.
Next, let’s pick one of our larger pumpkins and have a parent cut it open so our Squash Scientist can see all of the amazing things that are inside of the pumpkin. There’s a whole other world to observe inside. Have your child get their hands in there and feel the pulp and seeds of the pumpkin. Talk about what that feels like. Does the inside of the pumpkin feel like the outside? How is it different or similar?
Once your child has gotten a good sense of what the pumpkin feels like inside, you can properly identify the anatomy of a pumpkin together. Have your child draw their pumpkin, color it, and label it.
Identify the following parts of a pumpkin:
2. Shell (or Skin)
6. Fibrous Strands (note: that this is the part that we cook and eat!)
The Math Inside
When you are done with the identification process, it’s time to count the seeds! Have your child remove and count all the pumpkin seeds and put those aside. Don’t forget to have them write down their findings. Later, you can roast your pumpkin seeds for a tasty snack or dry them and have your child create a pumpkin seed shaker using a recycled plastic water bottle or can.
The Life Cycle of a Pumpkin
If you have a garden or space to plant, be sure to save a few seeds to try growing your own pumpkin later. Speaking of growing a pumpkin, let’s take a good look at a pumpkin seed and talk about the life cycle of a pumpkin. What does it take to turn that little seed into a fully grown pumpkin? Once you add the essential elements of light, water, and nutrient rich soil, the seed is unlocked.
Wanting more pumpkin science?
Talk about the science of cooking the pumpkin. Make some pumpkin soup or pie! Observe what happens when an adult heats up the fibrous strands in a pan? What texture is the soup or pie after it is finished cooking or baking? And most importantly, what does it taste like?
Looking for something more explosive?
Create a pumpkin volcano with your child using warm water, baking soda, dish soap and vinegar. You can find plenty of fun tutorials on Google and YouTube.
And for older children who are ready to move on and learn all about the concept of xylem and phloem you can check out how farmers grow those giant pumpkins.
As we combine “Science’ and ‘Fall’ together, we fascinate children with a wonderful list of pumpkin science experiments. These experiments also build a bridge between science and art activities that teach a variety of simple and complex scientific concepts to the young scientists in our homes and in school. For the inquisitive kids of all ages, these easy and cool experiments offer a great time to explore pumpkin science in a fun and exciting way.
