Easy Fall Science

I love fall or autumn, and especially fall science activities. The season is changing with beautiful leaves. There are acorns and nature to explore! The smells are fantastic! Crisp fall air, apple orchards, harvesting, and more!

Our favorite fall themes include leaves, apples, and pumpkins! We love heading out to the orchards and pumpkin patches as well as wagon rides. There is always so much to explore!

There are so many opportunities to experience fall themes with easy fall science experiments and hands-on activities. Fall science is a great way to learn about the many parts of fall we enjoy so much!

Many of these science experiments below are favorite science experiments with a fun fall twist!

These fall science activities also incorporate a great deal of sensory play and provide sensory stimulation for our younger kiddos. Easy enough to do with even the youngest child. Add in the scientific method (read more below) for older kiddos! Great fall science activities for preschoolers to elementary!

Using The Scientific Method For Kids

The scientific method is a process or method of research. A problem is identified, information about the problem is gathered, a hypothesis or question is formulated from the information, and the hypothesis is tested with an experiment to prove or disprove its validity. Sounds heavy…

What in the world does that mean?!? The scientific method should simply be used as a guide to help lead the process. It’s not set in stone!

You don’t need to try and solve the world’s biggest science questions! The scientific method is all about studying and learning things right around you.

As kids develop practices that involve creating, gathering data evaluating, analyzing, and communicating, they can apply these critical thinking skills to any situation. Click here to learn more about the scientific method and how to use it.

Even though the scientific method feels like it is just for big kids…

This method can be used with kids of all ages! Have a casual conversation with younger kiddos or do a more formal notebook entry with older kiddos!

Helpful Science Resources To Get You Started

Here are a few resources that will help you introduce science more effectively to your kiddos or students and feel confident yourself when presenting materials. You’ll find helpful free printables throughout.

Explore Nature For Fall Science Too!

Simply getting outside and going on a fall-themed scavenger hunt is a terrific way to start off a fall science lesson. You can collect samples to add to a fall-themed discovery table. We made these simple Fall discovery bottles when we were hanging out in our backyard.

Great Questions To Ask

Encourage kids to explore, learn and make observations by asking good questions.

  • What do you see?
  • What do you hear?
  • What do you feel?
  • What do you smell?
  • Even what do you taste? {like our apple 5 senses taste test}
  • What is happening?
  • What would happen if…?
