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. Be sure you understand lab safety considerations before you start.

by Theodore Gray

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.

Chemistry Simulations 

The Interactive Library is about “real interactivity”! The database contains hundreds of activities that make use of sophisticated java, vrml and shockwave programs. For those who can’t afford the mess.

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.



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.

Compounds and Mixtures

NIOSH Pocket Guide to Chemical Hazards
The National Institute of Occupational Safety and Health provides this database of chemicals. Use it to keep you and your family safe when experimenting with chemicals.






Element Games
Online and off you can play these games to help you remember the elements.

Elements at Walmart (31)
It’s amazing how many elements you can buy in reasonably pure form at Walmart: My list currently contains 31 elements. (When I say “Walmart” I really mean any combination of grocery store, hardware store, and pharmacy.

Homemade Hydrogen
There is a world of difference between watching someone use a special aparatus to make hydrogen in front of the class or on television, and doing it yourself using nothing you don’t already have at home right now.

The Structure of Metal
At the atomic heart of metal is a crystalline structure-tightly packed atoms arranged in orderly rows. This feature explores this heart and reveals what it is that gives metal its special characteristics and how metal behaves under the stress of heat and outside forces.


Periodic Tables

Chemical Elements
My name is Yinon Bentor, and I created Chemical Elements.com as my 8th grade science project several years ago. Since then, I have continued to update the site in my free time, and the site is now very different from the original design.

Comic Book Periodic Table of the Elements
Come meet Metal Men and the lovely Platinum and other superheros of the Table of Elements.

The Elements, by Tom Lehrer
Sing along with Professor Tom Lehrer as he sings the elements of the periodic table in this Flash animation.

The Periodic Table
Acrobat Files of the Periodic Table arranged in different formats. You are welcome photocopy these and distribute to students.

The Periodic Table
The Periodic Table is nature’s rosetta stone. To chemists the periodic table reveals the organizing principles of matter, which is to say, the organizing principles of chemistry. At a fundamental level, all of chemistry is contained in the periodic table.

Printable Periodic Table of Elements
Includes the Atomic Number, Atomic mass, Symbol, Name, Electronegativity, Density, Ionization energy, Boiling point, Melting point, Electron Configuration, Oxidation States, Ground State Level, Covalent radius, and Van der Waals radius. If you typically work with a different set of properties, you can download the spreadsheet and add in your own numbers.

The WebElements Scholar Edition
A high quality source of information on the WWW about the periodic table for students. You will find many pictures showing element structures and periodic properties.

The Wooden Periodic Table Table
A real table with cups under each block of wood, holding the actual element. Loads of information about each element, too, should you want to collect your own.


Free Chemistry Lessons

So you’re asking, what is CHEMISTRY? Well…here’s our best definition. Chemistry is the study of MATTER and the changes that take place with that matter.

Chemistry 11
Jeremy Schneider made a concerted effort to use the textbook as little as possible (just in case it changed again in the future). Thus, most of these lessons do not require a textbook. Any Nelson references that do appear can usually be substituted for with another basic chemistry text.

This tutorial begins with the fundamentals and gives expert help with the most difficult phases of understanding your first course in chemistry.

Coursera Chemistry Courses
These courses change constantly, and are in many languages from all over the world, so select your language preference. For teens, look first for general concepts courses, and work your way from there. When I looked there was a Forensic Science course being offered.

Creative Chemistry
Chemistry puzzles, interactive revision quizzes, molecular models, and the Sc1 Tune-up Garage to help improve your GCSE science investigations. Everything you need for your Chemistry Club.

General Chemistry Online
For self-motivated teens, this is a free complete chemistry course right on the web.

MIT courses, but suitable for teens.
