Science, Math, and…Pumpkins?

Pumpkins aren’t just great for Jack-O-Lanterns, they’re learning tools, too. This fall, spend a little time exploring pumpkins together with your kids — You might be surprised at how many ways you can apply math and science to this favorite fall fruit!

Exploring Pumpkins
Before carving this year’s Jack-O-Lanterns, measure your pumpkins together. Measurements can include weight, height, and circumference. Pumpkins are also great for lessons in buoyancy. You can even estimate and then count the number of seeds inside the pumpkin for practice counting high numbers.

Pumpkin Buoyancy:
Do you think your pumpkin will float if you place it in a bathtub filled with water? Do you think that it will float after you’ve carved it? Experiment by filling the bathtub or sink with water and placing the pumpkin in the water when it’s whole and again after it’s been carved. Was there any difference?

This just seemed like a fun photo to share with you for this topic!

Pumpkin Weight:
How much does your pumpkin weight before carving? How much does it weigh after you’ve carved it? How did the pumpkin’s weight change?

Pumpkin Measurements:
How tall is your pumpkin at its tallest point? How tall is your pumpkin if you don’t count the stem? What is your pumpkin’s circumference? Will those measurements change when you carve your pumpkin? Why or why not?

Pumpkin Seeds:
Do all pumpkins have seeds inside? How many seeds do you think your pumpkin will have inside of it? After cutting your pumpkin open (so that you can see the seeds) has your guess changed? How many seeds are really inside the pumpkin? Was your guess greater than or less than the number of seeds inside your pumpkin?

For Bonus Points: Can you find 3 ways to use the seeds from your pumpkin? A hint: you can eat them!
