Chemistry Experiments For Kids

*This post contains affiliate links. Things you buy through our links may earn us a commission.

Fun, simple chemistry experiments and easy projects kids to teens in high school can do at home using household materials to create really cool chemical reactions.

Since chemistry is a process, not just a collection of facts, homeschool children should be encouraged to do what real chemists do: make predictions, design and modify experiments, make observations, and draw reasonable conclusions. No liability for personal injury or damage to property or facilities will be assumed by A2Z Home’s Cool in connection with these activities and experiments. Be sure you understand lab safety considerations before you start.

Household Chemistry

by Theodore Gray
Read Inside

In his highly anticipated sequel to The Elements, Theodore Gray demonstrates how the elements of the periodic table combine to form the molecules that make up our world.

Everything physical is made up of the elements and the infinite variety of molecules they form when they combine with each other. In Molecules, Theodore Gray takes the next step in the grand story that began with the periodic table in his best-selling book, The Elements: A Visual Exploration of Every Known Atom in the Universe. Here, he explores through fascinating stories and trademark stunning photography the most interesting, essential, useful, and beautiful of the millions of chemical structures that make up every material in the world.

Acids and Bases

Acid Rain Experiments
Start with learning how to measure the pH of common substances, and then move on to determining the amount of acid in soil and streams. Teachers Guide.

Alka-Seltzer Student Science Experiments
The familiar fizzing you hear when you drop an Alka-Seltzer tablet into a glass of water is the result of a chemical reaction. It’s also the perfect tool for demonstrating some very nifty science principles; things like the factors affecting the rates of chemical reactions, or the colors produced by a chemical reaction. The following are some science experiments appropriate for in-school or at-home use.

Cabbage Juice – pH indicator
Make your own acid/base indicator by boiling red cabbage. Use the juice to pH-test different fluids.


Crystal Ornament
Whether it’s Christmas time or not, Borax crystals are easy to create and lovely to look at.

Charcoal Crystal Garden
Colorful, small, delicate crystals grow on a charcoal or brick surface. You can also use pieces of sponge, coal, or crumbled cork to grow the crystals on. Crystals are formed because the porous materials they grow on draw up the solution by capillary action.

Mrs. Stewart’s Bluing Original Magic Salt Crystal Garden
Mrs. Stewart’s Bluing is a colloidal suspension of extremely minute particles of blue powder (Ferric Hexacyanoferrate). You can order bluing or the whole kit on this website, if you wish.

Hot and Cold

Dry Ice Experiments
ERock-it Science Director John McChesney presents several homeschool science experiments showing the fascinating properties of Dry Ice. This video also includes one of John’s crazy stories, “Seven Dungeons,” in which Jack and Jill must use dry ice to escape from their nemesis, “The Evil Mr. Fred.” Rock-it Science is a nonprofit serving the Silicon Valley area.

The demonstrations in this chapter present special hazards, since most involve very hot or extremely cold substances, volatile chemicals, fragile glassware, high-pressure gases or evacuated containers.

Steel Wool Generating Heat
Chemical reactions occur every day all around us. A chemical reaction is a process where one type of substance is chemically converted to another substance.

Household Chemistry

Better hair Through Chemistry
I realized that a little bit of understanding could reduce the number of Bad Hair Days I experience. Scientific knowledge and a few chemical concoctions will get me through the week and a half until I get my hair back into acceptable shape.

The Chemistry of Dyeing: Reactive Dyes
How does tie-dying work anyways? Why does the dye stick permanently to cotton material? For big and little kids.

Creative Chemistry
There are full-colour worksheets and teaching notes for fun activities suitable for a chemistry club, and around three hundred pages of question sheets and practical guides for GCSE and A Level Chemistry.

The Exploratorium Science Snacks about Chemistry
Bubbles, making a fog chamber, why milk makes some people sick, how taste works, and more.

Gak Recipe
A visco-elastic substance, rather like putty, that is fun to make and play with. Oobleck and Glorax recipes included. Resources for getting large quantities of the chemicals.

How to make fun glycerin soap
You can quickly and easily make a set of fun and cute or elegant glycerin soaps. I am a chemistry teacher so I make them for my students to use to wash their hands after labs. Since I am using them in school I don’t add any fragrance but I will explain how and when you can do that.

Read Inside

For students, DIY hobbyists, and science buffs, who can no longer get real chemistry sets, this one-of-a-kind guide explains how to set up and use a home chemistry lab, with step-by-step instructions for conducting experiments in basic chemistry — not just to make pretty colors and stinky smells, but to learn how to do real lab work.



Make Stuff
Formulas for lotions, potions, concoctions and remedies you can make at home.

Potential Hazards in Your Home
A lesson plan for a high school-level experiment identifying household chemicals and understanding their possible effects.

Soap Chemistry
To understand what is needed to achieve effective cleaning, it is helpful to have a basic knowledge of soap and detergent chemistry.

Stain Removal From Washable Fabrics
Sharon Stevens explains practical household uses of chemicals to remove stains from various sources.
