science experiments with pumpkins


Every science experiment with pumpkins should include all parts of the scientific method to be a true science experiment, rather than just a demonstration.

Science demonstrations are a fun way to introduce a concept, but children should go through the scientific process on their own after watching the demonstration.

The more variables and tests children run the better!

Your science experiments should include:

  • Question or hypothesis
  • Testing
  • Analysis
  • Recording of results
  • Re-testing if necessary

Including these science elements will make every science experiment full of learning, critical thinking, logic, and fun!

Use our science experiment worksheet to get started recording the information from your pumpkin science activities.

Exciting Pumpkin Science Experiments for Kids

This list of pumpkin experiments will help kids learn about chemistry, biology, physics, properties of matter, states of liquid, density, and a whole lot more!

These pumpkin science activities are designed with kids from preschool to fifth grade in mind! Use the easiest activities for preschoolers, and the more advanced lessons for older kids.

Try the experiments one at a time, or do several in one day for a pumpkin science palooza!
