Chemistry is so much fun, and we have tons of cool chemistry experiments to share with you. Like our awesome physics experiments, we decided we needed to put together a list of fun chemistry projects kids can do at home or in the classroom. Check out these examples of easy chemical reactions below!


Chemistry is cool and we have the coolest chemistry activities for kids to share with you. Just like our awesome physics activities, we decided we needed to put together a chemistry experiments checklist for you. Don't miss a single experiment because each one is totally unique and yes, very cool too. We love homemade science.


Here you will find over 30 simple chemistry experiments for kindergarten, preschoolers, and elementary kids to enjoy at home or in the classroom. The only difficulty will be deciding which science experiment you want to try.

Below you will find a fun mixture {no pun intended} of chemistry activities that include chemical reactions, mixing saturated solutions, acid, and bases, exploring the solubility of both solids and liquids, growing crystals, making slime, and so much more!

Our science experiments are designed with you, the parent or teacher, in mind!  Easy to set up, and quick to do, most activities take only 15 to 30 minutes to complete, and are heaps of fun. 

Plus, our supply lists usually contain only free or cheap materials you can source from home. Any of these chemistry experiments below would be great for chemistry at home.


Let’s keep it basic for our younger or junior scientists! Chemistry is all about the way different materials are put together, and what they are made up of, think atoms and molecules.

It’s also about how these materials act under different conditions. Chemistry is often a base for physics so you will see some overlap.

What might you experiment with in chemistry? Classically we think of a mad scientist and lots of bubbling beakers, and yes there is a chemical reaction between bases and acids to enjoy! However, chemistry also involves matter, chromatography, solutions, and the list goes on.

Science encourages curiosity and asking questions. These simple chemistry experiments below will also encourage problem-solving skills and observation skills. Even the youngest of kids can enjoy a simple science experiment.

Take for example our very first baking soda science experiment. So simple to set up, but so lovely to watch the amazement on my son’s face.

That’s the best part of science for kids. It surrounds them, and it’s in every new experience they encounter! Whether you are exploring kitchen science or science in the backyard, each day is filled with an amazing new ideas and concepts just waiting to be discovered.

Encourage your kids above all to never stop questioning and by all means, try to answer those questions as best as possible or show them how you can find out the answers together. As parents, we don’t have to know everything!  But we do need to make sure we help our kids find the answers they are looking for.

Can you do cool chemistry experiments at home? You bet! Is it hard? Nope!

What do you need to get started? Simply get up, walk into the kitchen, and start rummaging through cupboards.  You are sure to find some or all of the supplies you will need for these chemistry projects below.

Why not make up your own DIY science kit from inexpensive items from the grocery store or the dollar store, and items you may already have at home. Fill a plastic tote with supplies and you will have a science kit filled with learning opportunities that are sure to keep them busy all year long.

Check out our list of must-have simple supplies for a science kit and a slime kit.

These science experiments at home work well with multiple age groups from preschool to elementary and beyond. Our activities have also been readily used with special needs groups in high school and young adult programs. Provide more or less adult supervision depending on your kids’ abilities!

Read on to find out our favorite chemistry experiments you can do in the classroom or at home, that are totally doable and make sense for kids in grades K-5! You can also review our lists for specific grades below.


Want to turn one of these fun chemistry experiments into a science project? Then you will want to check out these helpful resources.


We have divided our chemistry experiments below into states of matter, chemical reactions, acids and bases, chromatography, solutions, polymers, and crystals. You’ll find that some experiments also explore concepts in physics.


Explore solids, liquids, and gasses through various simple science experiments. Plus look for a fantastic free printable pack to go along with your states of matter lesson plans.


A chemical reaction is a process where two or more substances react together to form a new chemical substance. This might look like a gas formed, cooking or baking, milk souring, etc.

Sometimes a physical change occurs, like our popcorn experiment or melting crayons, rather than a chemical change. However, these experiments below are all great examples of chemical change, where a new substance is formed.

Can chemical reactions happen safely at home or in the classroom? Absolutely! This is one of the most fun parts of chemistry for kids, and you will find lots of ideas below for safe chemical reactions you can do with your junior scientists.

Acids and bases are important for many chemical processes in everyday life. An acid has hydrogen ions and can donate protons. Acids taste sour and have a pH from 0 to 7. Vinegar and citric acid are examples of acids.

Bases are molecules that can accept hydrogen ions. They have a pH higher than seven and can taste bitter. Sodium bicarbonate or baking soda and ammonia are examples of bases. Learn more about the pH scale.

Vinegar and baking soda experiments are classic acid-base reactions. You’ll also find experiments that just use an acid such as vinegar or lemon juice. We have so many fun variations that your kids will love to try! Check out these acid-base chemistry experiments below.

Chromatography is a technique that involves the separation of a mixture into its parts so you can see each one individually.

This marker and paper chromatography lab uses chromatography to separate the pigments in a black marker.

Or set up a leaf chromatography experiment to find the hidden pigments in the leaves in your backyard!

A solution is a mixture of 2 or more solutes dissolved in a solvent up to its solubility limit. It most often refers to liquids, but solutions, gases, and solids are also possible.

A solution will have its components evenly distributed throughout the mixture.

Chemistry experiments involving solutions are great for kids. Gather liquids you commonly find in your kitchen, oil, water, detergent, etc., and explore what dissolves.

A polymer is a huge molecule made up of many smaller molecules layered together in repeating patterns called monomers. Putty, slime, and cornstarch are all examples of polymers. Learn more about the science of slime polymers.

Making slime is great for at-home chemistry and is also tons of hands-on fun! It’s also a classic middle school science demonstration for the classroom. Here are a few of our favorite slime recipes to get you started.

A crystal is a solid material with a highly ordered internal structure of atoms, molecules, or ions held together by chemical bonds.

Grow crystals and observe them by mixing up a super-saturated solution and leaving it for several days to let the crystals form.

Simple to grow and taste-safe, a sugar crystals experiment is more accessible for younger kids, but you can also try growing borax crystals for older kids.

Check out our fun theme variations of growing crystals too!
