What is a Chemistry Experiment?

Wikipedia defies chemistry as:

The branch of science that deals with the identification of the substances of which matter is composed; the investigation of their properties and the ways in which they interact, combine, and change; and the use of these processes to form new substances.

Because chemistry is involved with matter, investigating matter, and learning about interactions between materials, chemistry science can be just about anything!

A chemistry experiment should help kids learn about the world and matter specifically. Chemistry is all about exploring the world and learning about how things interact with each other.

These fall chemistry experiments focus on chemistry with fun fall themes, which makes it a bit more fun for kids who might be a bit more reluctant to explore science and chemistry!

Before high school, chemistry is more of an exploration and less math, so it’s the fun part!

If you like these chemistry experiments, you’ll also love our creative STEM activities and science experiments for kids!

And we have fun lists of science experiments for elementary and science experiments for middle school, too!

How to Do Chemistry Experiments with Kids

Don’t miss this list of fall STEM activities for kids, or these fall STEM challenges for middle school!

A chemistry experiment for a child should allow them to find out what happens when things interact, mix, and change.

Because chemistry is so hands on, most kids love it!

The most important thing to remember is that children need to be taught good lab safety practices, even with these relatively safe chemistry activities.

These fall chemistry experiments are perfect for kids exploring chemistry in elementary or middle school!

Middle school and elementary students will love these hands-on chemistry experiments for the classroom (but you can also do them at home!).

Now on to the list of fall chemistry experiments for kids!

Chemistry Experiments for Kids with a Fall Theme!

fall chemistry experiments for middle school

If you want to explore the chemistry of how substances can change when mixed with other chemicals, try making fall leaf slime!

Make an exothermic reaction using yeast and hydrogen peroxide!

Lern about how chemistry can change the molecular bond of subtances when you make fluffy apple slime.

The dancing popcorn experiment shows children how states of matter can be influenced by chemical reactions and how byproducts can be created when certain chemicals mix.

Explore chemical reactions inside of a pumpkin when kids make a pumpkin volcano.

Kids can learn about solutions, mixtures, and states of matter when they make salt crystals!

We have tutorials for salt crystal leaves, salt crystal apples, salt crystal pumpkins, and salt crystal feathers!

We may have gone a bit overboard on the salt crystals, but my kids love them!

In the how to make butter experiment, kids can learn how motion and shaking can change the state of a liquid to another state and cause molecules to bond or separate.

If you love fall, and you love chemistry, you'll love these fall chemistry experiments for kids!

Try the leaf chromatography experiment and learn how chemists use chromatography paper to identify chemicals and concentrations of materials in a solution.

Chromatography is one way that chemistry scientists prove that a substance is what it says it is!

Make a fall lava lamp and explore chemical reactions.

The fall mad scientist’s lab is another fun twist on the classic baking soda and vinegar reaction.

Make boiling slime and discover how adding different substances to a classic mixture can change the reaction!
