When the leaves start to turn colors and temperatures start to drop, it’s time for fall science experiments. These autumn science experiments are perfect for elementary!

Fall science activities are the perfect way to celebrate the turning of the season when it’s too early to do Halloween STEM activities but it’s too late to do back to school STEM activities!
Of course, you can also do fall science projects right after Halloween before you do Thanksgiving STEM activities and science experiments.
Round out your year of STEM activities with this complete list of science experiments for fall.
And check out this list of fall science experiments for kindergarten!

What is a Fall Science Project?
A fall science experiment is no different from any other science experiment, except that a fall theme is used when exploring the science experiment.
A science experiment for fall includes fall themes, like apples, pumpkins, acorns, corn, cranberries, leaves, hay, and other staples of fall.
Many common science experiments can be done with a fall twist, simply by changing the colors of the experiment, adding fall elements instead of the traditional science elements, or by using fall themes to illustrate each scientific concept.
Fall science activities are just as easy to do in the classroom as at home, and both science teachers and parents and grandparents can have fun with science using fall themes.

WHY DO SCIENCE EXPERIMENTS FOR FALL WITH KIDS?

There are a lot of reasons to keep science experiments topical, like these autumn science experiments.
One of the biggest reasons is that during the fall, you have access to fall-like materials, including leaves, acorns, pinecones, candy corn, and other commonly used supplies for fall science experiments.
It’s easier to do these fall science experiments when the supplies are easier to get. Additionally, kids are more interested in science when it’s relatebale to them.
A lot of science experiments can get theoretical, which may make the concepts difficult for children to grasp.

When normal themes are brought into the mix, kids are better able to grasp how and why science concepts work, which makes them score higher on science tests and exams.

How to Do Fall Science Activities with a Group

If you’re doing these science experiments for fall in a group setting, you’ll want to adapt the instructions slightly, and make sure to follow these important tips:
Stay organized
If you’re not organized when you teach a hands-on science experiment, kids will get off track quickly, and you may never regain control of that class.
To prevent this, make sure you have everything laid out for each group of kids ahead of time, so that there is minimal distribution and clean-up time.
Have a science worksheet for every child
In a group setting, it will be harder for kids to record their data. If you use a science worksheet ( we have a free one), then kids will easily be able to keep track of their progress and thoughts without you having to hold their hands every step of the way.

Know the lesson well
Kids love to poke holes in adults’ words, so make sure you know everything there is to know about the topic before presenting it to the group.
Keep explanations short
The longer you spend explaining the project, the more kids will get bored and lost. Explain the science quickly and simply so the children understand before they get bored.
Plan for things to take longer
Things always take longer in a group. Usually, adding additional kids will double the expected experiment time, so be prepared for that.
