55 Best Science Experiments for High School Labs and Science Fairs

Fire up the Bunsen burners!

WeAreTeachers Staff

The cool thing about high school science experiments and projects is that kids are old enough to tackle some pretty amazing concepts. Some science experiments for high school are just advanced versions of simpler projects they did when they were younger, with detailed calculations or fewer instructions. Other projects involve fire, chemicals, or other materials they couldn’t use before.

Many of these science experiments for high school are intended for classroom labs, but most can be adapted to become science fair projects too. Just consider variables that you can change up, like materials or other parameters. That changes a classroom lab into a true scientific method experiment!

(Just a heads up, WeAreTeachers may collect a share of sales from the links on this page. We only recommend items our team loves!)

110 Awesome Chemistry Experiments For All Ages

Chemistry experiments are a great way to get kids excited about studying chemistry even at a young age. I mean, what child doesn’t think about creating bubbling potions or sending secret messages?

The study of chemistry has a scary connotation for many people. Chemistry has this stigma of being only for really, really smart students who want a career in the sciences. The truth is that, like all science, chemistry is everywhere.

In fact, chemistry experiments for kids can be bubbly and full of fungi! Check out the video below of our Making Peeps Blow Up a Balloon chemistry activity.

It is in the way water freezes into ice . It is in the way apples turn brown when you leave their flesh exposed to the air. Chemistry is in the way sugar dissolves in water .

How does chemistry apply to our bodies? Check out our version of the egg with vinegar experiment . We added a little twist that makes an excellent connection between chemistry and our dental health. We have a 25+ page printable pack to go with it for just $2.95 .

Showing how chemistry is involved in everyday life can take that scary factor out of studying chemistry for students. When it comes time to study chemistry, they will be more excited about jumping in.

Chemistry experiments for children in K-12. 100 different chemistry experiments divided into 3 age/grade ranges. Many are ideal when teaching multiple grades at one time in your homeschool, classroom, or co-op.

Chemistry Experiments For All Ages

I wanted to create a resource for you to be able to find the perfect chemistry experiments for your students no matter their age or interests. This post contains 100 chemistry experiments for students from preschool age through high school. I have divided them into 3 age ranges.

Here are a few disclaimers to my divisions of the experiments.

I realize that all students are different and are ready for different levels of experiments. For instance, some students in the elementary age group might be ready for more advanced experiments found in the Middle and High School section, while others need something more basic like those experiments found in the Preschool and Primary section.

Some may question why I put certain experiments in certain sections. First, I looked at the level of maturity I felt needed to conduct the experiment and if parental help was necessary. Next, I looked at the level of understanding the child would need to learn from the experiment.

Some experiments could teach something at different levels or could be done with parental help or independently and still be successful. When this was the case, I put the experiment in the lowest recommended age level.

With all that being said, these are just guidelines. Feel free to try experiments in sections that differ from your students’ age range if you think they would work.

Easy Chemistry Experiments for Kids

October 19, 2021 By Emma Vanstone 1 Comment

When I think back to my own childhood and school days, I don’t remember any chemistry experiments until secondary school, which is a shame because there are so many wonderfully visual easy chemistry experiments for kids that can be done at home or in school with young children.

I’ve put together a collection of my favourite examples, do let us know if you try any.

  Please remember young children should be supervised at all times.

Chemistry Experiments for Kids in the Kitchen

Exploding sandwich bags .

I did struggle a little when we tried this as the reaction happens so fast, but  Steve Spangler has a nifty method where he traps the vinegar in a second smaller bag, which you then have to burst to get the reaction started.

Exploding sandwich bags. Two sealable packs with food colouring, baking soda and vinegar inside for a chemistry experiment.

Inspiration laboratories add a twist by adding some colour and making  firework pictures at the same time.

Blow Up a Balloon

This is a super simple demonstration or experiment that has never failed me, and all you need is a container with a small neck, a balloon and either an alka seltzer or effervescent vitamin tablet. The alka seltzer or vitamin tablet react with water to release bubbles of carbon dioxide filling the jar and then blowing up the balloon.

Blow up a balloon with alka seltzer

Find out how to blow up a balloon with lemon juice and baking soda.

Colourful Milk

Make a lovely, colourful display using milk, food colouring and vinegar.

Oil, Food Colouring and Water Exploration Table

This oil, water and food colouring exploration table is brilliant for even very young children. For older children try a more structured approach, they could measure the amount of vinegar and baking soda needed to make the reaction spill over the top of the beaker, or try dropping tiny amounts of coloured water into the oil.

Density Rainbow Jar

Learn about the tricky concept of density and make a beautiful demonstration density jar .

Image of a density column made with honey, golden syrup, washing up liquid, coloured water and oil

Simple Density Jar

If you don’t want to make as many layers as we have, why not try this smaller version and try to find an object to float on each layer.

Lemon Volcanoes

This lemon volcano from Babble Dabble Do is a great alternative to the traditional volcano and handy as the lemon already contains the acid.

Clean coins

Did you know you can clean coins with vinegar ?

coins, some cleaned with vinegar and some dirty

Colourful Chemistry Experiments

Make your own ph indicator.

Test ph of vinegar and baking soda with a red cabbage indicator . What do you think might happen if you blow into the indicator?

Dissolving Skittles

Watching the colour dissolve from skittles or M & Ms dissolve into water is a lovely, quick, visual activity.

Chemistry Experiments for Kids Outside

Giant bubbles.

Who doesn’t love a giant bubble ? Red Ted Art makes bubble making look easy in this great video. Remember the mixture gets better the longer you leave it, so allow plenty of time.

Make a Square Bubble

All you need to make a square bubble is a square frame.

Coke and Mento Reaction

The infamous coke and mento reaction is super easy and very impressive to watch. Try comparing the size of the geyser using diet and full sugar cola, or using different types of fizzy drinks.

Can you design something which allows the mentos to drop in as soon as you remove the lid?

Coke and Mento reaction. Image shows coke flying into the air!

Elephants Toothpaste

Fun at Home with Kids makes elephants toothpaste   look super simple, but do be careful with the hydrogen peroxide and take appropriate precautions.

Film Canister Rockets

Film canister rockets are easy, inexpensive and great fun. All you need is a film canister, effervescent vitamin tablet and some water. Experiment with different amounts of water and tablets to find the most explosive combination.

Chemistry Separation Methods

Bicycle centrifuge.

Did you know you can use bike wheels as a very basic centrifuge ?

Stone and Gravel Filter

Learn about filters by making a filter with stones , gravel and sand.

Filter Paper Chromatography

Take on the role of detective with some fun filter paper chromatography .

Top 10 Chemistry Experiments You Don't Want to Miss

May 03, 2021 3 min read

A few years back we shared a series about how to teach the different areas of science at home, which you can find here:

The posts in the series have remained some of our most popular posts and so we thought we would help you all out by sharing our favorite experiments for each discipline!

So far we have shared our favorite biology , earth science , and astronomy experiments. Today, we are going to share ten of our favorites for chemistry.

And without further ado, here are our top 10 chemistry experiments!

Top 10 Chemistry Experiments

Don't miss these top ten favorite chemistry experiments from Elemental Science.

1. Explore marker chromatography.

This STEAM activity versatile enough to do with what you have on hand and definitely delivers the "WOW" factor.

It's a great project for   decorating a tree, making   beautiful butterflies, or for making a scientific version of a   tie-dye t-shirt. Whatever you decide to do with your marker chromatography artwork, the process is the same.

2. Test which one freezes first. 

Winter is a great time to explore the principles of chemistry through experimentation! Although, with a freezer you can enjoy this experiment year-round.

This simple experiment will help your students to see   how salt changes the freezing point of water .

3. Make a bioplastic in your kitchen.

This chemistry experiment shares how to make a simple bioplastic in your microwave!! What is a bioplastic you ask? It's a plasticky material made from biological chemicals.

Now, we can't exactly make a completely hard bioplastic in our microwave. However, we will make a super cool gel-like bioplastic using cornstarch and a few other items.

4. Polishing silver with chemistry.

I know you are thinking - silver polish can't possibly be a super fun chemistry experiment. But, the directions in this post contain the best possible homemade silver polish.

Uncle Cecil and President Lincoln of Sassafras Science fame tried hundreds of experiments just to make sure. This silver-polishing, scientific magic trick will make an afternoon chore into a super fun chemistry experiment.

5. Experiment with Borax.

Borax is an old-school laundry booster that many of the slime recipes use. But what do you do with the rest of the box when you are done? 

You could get all retro and add it to your next load of laundry, but what fun is that? Today, we are going to share with you three chemistry experiments that use Borax - ones that you will want to do over and over again until the whole box is gone!

6. Do a kitchen acid test.

A kitchen acid test is always fun because of the color changes.  But more than that, this hands-on science activity is a great way to show your kids a bit about the chemistry of acids and bases!

7. Send a secret message.

You use chemistry to be like a spy and send a secret message ! This  kitchen science activity is one you can use over and over again.

8. Explode fireworks in your kitchen.

There is a lot of chemistry behind fireworks - the colors alone are due to different chemicals!

And although, you can't explode actual fireworks in your kitchen, but you can learn about them and then do a simple chemistry experiment to see fireworks in your kitchen !

9. Play with dry ice.

Dry ice is a fun way to explore the states of matter. It's one of those materials that appear to boil in room temperature water, sending out billows of white, wispy smoke.

This post shares three  chemistry activities with dry ice from our lab to yours that you can use to explore this amazing material.

10. Mix up a batch of crazy colors.

This chemistry experiment is part color-change , part stink-up-the-kitchen and it requires a bit of preparation, but it is totally worth it! It's one of the best ways to show the difference between acids and bases.

Wrapping it Up

There are loads more options for chemistry experiments out there that we love - in fact, we probably could have done a post with 100 experiments! But these are the ten we don't want you to miss.  If you want more chemistry experiments, check out our   Chemistry Pinterest board .

Interesting High School Chemistry Demonstrations

High school science students can be hard to impress, but here's a list of cool and exciting chemistry demonstrations to capture student interest and illustrate chemistry concepts.

Sodium in Water Chemistry Demonstration

Getty Images / Andy Crawford and Tim Ridley 

Sodium reacts vigorously with water to form sodium hydroxide . A lot of heat/energy is released! A very small amount of sodium (or other alkali metal) produces bubbling and heat. If you have the resources and space, a larger amount in an outdoor body of water forms a memorable explosion. You can tell people the alkali metals are highly reactive, but the message is driven home by this demo.

Leidenfrost Effect Demonstrations

The Leidenfrost Effect occurs when a liquid droplet encounters a surface much hotter than its boiling point , producing a layer of vapor that insulates the liquid from boiling. The simplest way to demonstrate the effect is by sprinkling water on a hot pan or burner, causing the droplets to skitter away. However, there are fascinating demonstrations involving​ liquid nitrogen or molten lead.

Sulfur Hexafluoride Demonstrations

Sulfur hexafluoride is an odorless and colorless gas. Although students know fluorine is extremely reactive and usually quite toxic, the fluorine is safely bound to sulfur in this compound, making it safe enough to handle and even to inhale. Two noteworthy chemistry demonstrations illustrate the heavy density of sulfur hexafluoride relative to air. If you pour sulfur hexafluoride into a container, you can float light objects on it, much like you would float them on water except the sulfur hexafluoride layer is completely invisible. Another demonstration produces the opposite effect from inhaling helium . If you inhale sulfur hexafluoride and speak, your voice will seem much deeper.

Burning Money Demonstration

Most high school chemistry demonstrations are hands-off for students, but this is one they can try at home. In this demonstration, 'paper' currency is dipped in a solution of water and alcohol and set alight. The water absorbed by the fibers of the bill protects it from ignition.

Oscillating Clock Color Changes

The Briggs-Rauscher oscillating clock (clear-amber-blue) may be the best-known color change demo, but there are several colors of clock reactions , mostly involving acid-base reactions to produce the colors.

Supercooled Water

Supercooling occurs when a liquid is chilled below its freezing point , yet remains a liquid. When you do this to water, you can cause it to change to ice under controlled conditions. This makes for a great demonstration that students can try at home, too.

Colored Fire Chem Demos

A colored fire rainbow is an interesting take on the classic flame test, used to identify metal salts based on the color of their emission spectra. This fire rainbow uses chemicals readily available to most students, so they can replicate the rainbow themselves. This demo leaves a lasting impression.

Nitrogen Vapor Chem Demo

All you need is iodine and ammonia to make nitrogen triiodide. This unstable material decomposes with a very loud 'pop', releasing a cloud of violet iodine vapor. Other reactions produce violet smoke without the explosion.

50 Chemistry Projects That Will Amaze Kids!

February 26, 2019 by Ana Dziengel 5 Comments

Chemistry projects feel like magic , do they not? If you think about some of your favorite science projects, the ones you love to try with your kids or the ones that amazed YOU as a kid, more likely than not most of them involved chemistry.

Now I know a lot of us associate chemistry with lab coats, beakers and specialty ingredients but the reality is there are so many chemistry projects you can do using very simple, easy to find ingredients, often found in your own pantry. And since these types of simple chemistry projects use relatively safe ingredients, they are perfect to try with younger kids, ie. preschool and elementary aged children! In fact I think it’s so important for young kids to have a positive association with chemistry from a young age that fosters a love of this branch of science.

When most children are finally exposed to chemistry in school, it is at the high school level where the subject turns complex quickly; hopefully giving kids a chance to have fun at young age mixing up concoctions and watching chemical reactions will help carry their interest through the more complicated days of study ahead.

This post is a GIANT compilation of  chemistry projects that would be great for the science fair, classroom demos, or at home science with your kids.

Before we get started let’s talk a little bit about what chemistry is and for parents I also included a section covering How to Do Chemistry Projects at Home. If you are a classroom teacher you can skip this section and head right to the projects here.

What is chemistry?

Chemistry is the branch of science that studies matter (anything that has mass and takes up space) and its properties, and how different substances (especially molecules and their atoms) interact, combine, and change to form new substances.

Here are some important definitions to know when working on chemistry projects:

While most people think of chemistry purely in terms of chemical reactions, chemistry also covers the study of the states of matter as well as the density of substances.

The five branches of chemistry are:

Read more about what each branch covers here.

How to Do Chemistry Projects at Home

Many chemistry projects can be done at home using simple materials and are a great way to foster a love of science in kids! I wholeheartedly believe that a wow factor in a project engages and inspires kids to learn more. If you want to try chemistry projects at home here are some suggestions and precautions:

Safety First

Even though most of the projects in this list use safe, easy to find materials they should be used with safety precautions and under adult supervision. Why? Sometimes the chemical reaction that ensues can irritate the skin or eye, can be harmful if swallowed, or is just plain sticky or  messy and adults should be on hand to supervise use . Also be advised that there are a few projects on this list that do use materials that are unsafe for kids to handle. These projects are meant to be demonstrations only and are labeled  accordingly.

Managing Messes

Chemistry Projects for Kids

The following chemistry projects for kids are sorted by topic: Chemical Reactions, Acids and Bases, Carbon Reactions, Chromatography, Colloids & Solutions, Polymers,  and Crystals.

Please note that many if these projects could fit in two or more categories in this post as they demonstrate various scientific and chemical processes. I only classified them once on this list.

Chemistry Projects with Chemical Reactions 

What is a chemical reaction.

Chemical reactions occur when the chemical bonds in a substance are either destroyed or created. In other words the bonds in a molecule are broken during a chemical reaction and the atoms rearranged to create new molecules. Interestingly enough the number of original atoms does not change during the reaction, they are simply reconfigured.

An easy way to explain chemical reactions to kids is to use this analogy: Atoms are like letters, molecules are like words. Chemistry is like taking apart words and rearranging the letters to form a new word.

Read more about chemical reactions here.

Chemical Reactions Projects:

1. milk painting, 2. citrus battery, 3. elephant toothpaste.

<span data-mce-type=”bookmark” style=”display: inline-block; width: 0px; overflow: hidden; line-height: 0;” class=”mce_SELRES_start”></span>

4. Density Lava Lamps

To make a density lava lamp fill a plastic bottle with the following liquids: Clear corn syrup, water with a few drops of food coloring, and  layer of vegetable oil. Be sure to leave a space at the top of the bottle. Wait until the liquids settle then add in a tablet of extra strength alka seltzer. Watch as the alka seltzer and water react and bubble up through the oil layer.   To see this in a  step by step video check out this video (Pssst this is one of our students!!!)

5. Plastic Milk   and Curds & Whey Experiment

6 . color mixing.

Pour water into three clear plastic cups, then add blue, red, and yellow food coloring to each. Have an additional cup full of uncolored water available as well. Give your child an empty ice cube tray and pipettes and let them create different colors by mixing different ratios of two different primary colors in each ice cube compartment. The secondary colors are new colors created from two primary colors. This is a simple visual of how chemical reactions work.

7. Chemistry Clock

8. blow balloons with yeast and sugar, 9. shiny pennies.

Acids are corrosive and sour tasting. Liquids such as vinegar, lemon juice, and tomato juice are acids. Pennies are made from copper which tarnishes (turns dark) when exposed to oxygen over time. Placing the copper pennies in an acid will clean the copper oxide off them and make them shiny again.

Learn about Acids and Bases

Most liquids are either an acid or a base. Liquids with lots of hydrogen ions in them are considered acids. Liquids with many hydroxide ions are bases. Scientists use a scale called the ph scale to measure how acidic or basic a liquid is. The more hydrogen ions in a liquid the more acidic it is and ranks low on the ph scale. The more hydroxide ions in a liquid the more basic it is and ranks high on the ph scale.  You can see what that looks like here.

When acids and bases are mixed chemical reactions occur and the solution becomes neutralized.

Acid and Bases Projects:

1. baking soda & vinegar volcano, 2. lemon volcano, 3. the colorful cabbage juice science experiment   and acid base experiment with cabbage, 4. dancing rice, 5. green eggs & ham, 6. bubbly citric acid brew , 7. baking soda vs baking powder science experiment, 8. exploding bags, 9. rainbow rubber eggs , 10. surprise eggs  , 11. rainbow wizard’s brew, chemistry projects with fire (carbon reactions).

Carbon is the most important element for life. Chemicals that contain carbon are called organic compounds.  Carbon has two main forms: The first is in the hard form of diamonds and graphite, and the second is the impure form found in charcoal, coal and soot.

SAFTEY WARNING: Carbon reactions are always fascinating to watch however the presence of fire means that these experiments must be supervised by adults at all times!  

Carbon Reactions Projects:

1. smoking fingers, 2. fire snake, 3. silver egg, 4. invisible ink, chromatography.

Chromatography is the process of separating mixtures. We usually think of it in terms of color hence the prefix -chroma, however in chemistry is means simply a method of separating mixtures by letting them slowly move past each other. It applies to both liquids and gasses.  This is wonderful in-depth explanation of chromatography.

Chromatography Projects:

1. chromatography  .

In this project you will separate the color black into other colors. Fold a coffee filter in half. Fold in half two more times until you have a triangular shape. Color the tip of the coffee filter with washable black marker. Get a good coat of ink on the filter. Add a small amount of water to a plastic cup. Place the black tip of the coffee filter in the cup Wait and observe. Come back to the filter after an hour or two and see what happens to the ink. As the coffee filter absorbs water through capillary action, the black ink moves through the filter and is separated by the water into other colors. You should see blue, green and even red as the water separates the ink.

2. Chromatography Flowers

3. chromatography art, 4. chromatography bags, colloids and solutions/solubility.

Colloids and Solutions are two types of homogenous mixtures.

If you want a more in-depth primer on solutions and colloids hop over here .

Colloid Projects:

1. colloid examples, 2.  oobleck  , 3. make butter , 4. gelatin streaking, solutions/solubility projects:, 5. ice sculptures , 6. ice cream in a bag.

A printable of the science facts at play here

7. Skittles Science

8. magical water blossoms  <span data-mce-type=”bookmark” style=”display: inline-block; width: 0px; overflow: hidden; line-height: 0;” class=”mce_selres_start”></span>, 9. diffusion art, 10. paint solubility  , 11. bleeding blossoms  .

A polymer is a substance made up of a long chain of molecules.  Polymers are typically flexible materials like plastic or gum.

The classic polymer kids LOVE to make is slime! Glue is already a polymer but when combined with sodium tetraborate (borax ) the protein molecules of the glue and the borate ions crosslink, making it harder for the molecules to move and forming the gooey, sticky, substance we know as slime.

Other polymers you are probably familiar with are plastic bags, balloons, instant snow, and even the powdery substance found in diapers that expands when wet.

Polymer Projects:

1. best basic slime  .

Bonus: Get the Science Behind Slime printable here

2. Heat Sensitive Slime

3. diy bouncy balls, 4. magic plastic bag experiment, 5. instant terrariums, 6. how to make paper, 7. skewer through balloon , 8. dry erase figure   and dry erase drawings, 9. recycled plastic flowers.

Crystals are a type of material that is formed by patterns of repeating molecules. There are four types of chemical bonds in crystals and therefore four categories of crystals. These are: Covalent, Molecular, Metallic, and Ionic Crystals. You can grow crystals by mixing up a super saturated solution (usually with a type of salt and water) and letting it settle over time so crystals will form. Check out the various types of easy to grow crystal below and go here to read more about the science of crystals .

Crystals Projects:

1. classic borax crystals , 2. overnight crystal garden, 3. egg geodes, 4. crystal wind catchers, 5. crystal landscapes, 6. candy geodes , 7. salt crystals, conclusion & more.

Alright you guys, do you feel like you have some good project ideas for exploring chemistry with kids? Many of these will make greats science fair projects. Be sure to start with them as a topic then start asking questions, form a hypotheses, and do some experiments.

Now I have to admit that I really fell in love with chemistry projects as an adult. Working with kids in camp, after school, and with my own kids at home I’ve had the chance to try fun chemistry projects and discovered that I love watching chemical reactions AND the reactions on the faces of kids and bystanders during demonstration or project!

If you have kids who fall in love with this branch of science please do check out the incredible book series Elements , Molecules , and Reactions by Theodore Gray (see the series in our Amazon science ideas list here ) The books are stunning, informative, easy to understand and, wait for it…funny!

Another valuable resource for kids who love chemistry is Mel Science’s Chemistry subscription box. They send you a starter kit for free with all the materials you’ll need and then each month you get a new chemistry experiment delivered to your door! This is great product because a lot of specialty chemistry ingredients are hard to find and these kits simplify getting the materials you need! Check it out here:
