Pumpkin Investigations

Fall is my favorite season of the year so I was excited to grab a pumpkin from our porch and sneak in some fall-themed STEM learning. This free pumpkin activity sheet is an easy way to practice math AND science!

Pumpkin Investigations

To get ready, I printed an activity sheet (below) for Middle Brother (age 5) and grabbed a few supplies:

  • A pumpkin (we used a small one but any size would work),
  • Unifix cubes,
  • Scale,
  • Bucket of water,
  • Piece of yarn (long enough to wrap around the pumpkin),
  • Ruler,
  • and a couple of crayons

Then I invited Middle Brother over to join me. I explained that we were going to use one of our pumpkins to practice some math and science. First up, we would find out how tall our pumpkin was.

I invited him to guess how many Unifix cubes he would need to reach from the top to the bottom. Then he jumped in and started building a stack, counting the cubes when he was finished.

Next up was weight so we placed our pumpkin on the scale and discovered that it weighed just half a pound. (Middle Brother couldn’t believe it because he tops the scale at nearly 50 pounds now!)

When he was ready, we grabbed the yarn and he wrapped it around the belly of the pumpkin. I helped him snip the ends so it was just the right diameter.

Then he stretched the yarn along the edge of a ruler to find its length.

Middle Brother’s favorite part came when he tested whether the pumpkin would sink or float. He was stunned to discover that his guess was wrong – our little pumpkin happily rested at the top of our bucket.

Our pumpkin investigation was such a fun way to sneak in some STEM learning! I hope your kids love it too.
