Easy Chemistry Experiments You Can Do at Home

Key Takeaways

You can make slime at home with simple materials, making it fun for kids and adults.
Create a sparkly borax snowflake that is safe and easy enough for kids to make.
Discover the fun of a Mentos and Diet Soda fountain with a spectacular explosive reaction.

Looking for fun, educational activities to do at home? This list of easy chemistry experiments and science activities will allow you to perform experiments with materials you likely already have in your kitchen cupboards.

Slime

You don't need esoteric chemicals and a lab to have a good time with chemistry. Your average fourth-grader can make slime, and it doesn't get any less fun when you're older, so this is a good at-home experiment for kids and adults alike.

Borax Snowflake

Borax crystal snowflakes are safe and easy to grow — Anne Helmenstine

Making a sparkly borax snowflake is a crystal-growing project that's safe and easy enough for kids. You can make shapes other than snowflakes, and you can color the crystals. If you use these as Christmas decorations and store them, the borax is a natural insecticide and will help keep your long-term storage area pest-free. If they develop a white precipitant, lightly rinse them but don't dissolve too much crystal.

Mentos and Diet Soda Fountain

This is a backyard activity best accompanied by a garden hose. The Mentos fountain is more spectacular than a baking soda volcano. If you make the volcano and find the eruption to be disappointing, substitute these ingredients.

Penny Chemistry

You can clean pennies, coat them with verdigris, and plate them with copper. This project demonstrates several chemical processes, yet the materials are easy to find and the science is safe enough for kids.

Invisible Ink

Invisible inks either react with another chemical to become visible or else weaken the structure of the paper so the message appears if you hold it over a heat source. But we're not talking about fire here; the heat of a normal light bulb is all that's required to darken the lettering. This baking soda recipe is nice because if you don't want to use a light bulb to reveal the message, you can just swab the paper with grape juice instead.

Colored Fire

Fire is fun. Colored fire is even better. These additives are safe. They won't, in general, produce smoke that is any better or worse for you than normal wood smoke. Depending on what you add, the ashes will have a different elemental composition from a normal wood fire, but if you're burning trash or printed material, you have a similar result. This is suitable for a home fire or campfire, plus most chemicals are found around the house (even of non-chemists).

Seven-Layer Density Column

Make a density column with many liquid layers. Heavier liquids sink to the bottom, while lighter (less dense) liquids float on top. This is an easy, fun, colorful science project that illustrates the concepts of density and miscibility.

Homemade Ice Cream in a Plastic Bag

Science experiments can taste good! Whether you're learning about freezing point depression or not, the ice cream is a delicious result either way. This cooking chemistry project potentially uses no dishes, so cleanup can be very easy.

Hot Ice (Sodium Acetate)

Got vinegar and baking soda? If so, you can make "hot ice," or sodium acetate, and then cause it to instantly crystallize from a liquid into "ice." The reaction generates heat, so the ice is hot. It happens so quickly that you can form crystal towers as you pour the liquid into a dish.

Burning Money

The "burning money trick" is a magic trick using chemistry. You can set a bill on fire, yet it won't burn. Are you brave enough to try it? All you need is a real bill.

Coffee Filter Chromatography

Exploring separation chemistry with coffee filter chromatography is a snap. A coffee filter works well, though if you don't drink coffee you can substitute a paper towel. You can also devise a project comparing the separation you get using different brands of paper towels. Leaves from outdoors can provide pigments. Frozen spinach is another good choice.

Baking Soda and Vinegar Foam Fight

The foam fight is a natural extension of the baking soda volcano. This easy chemistry experiment is a lot of fun and a little messy, but quick enough to clean up as long as you don't add food coloring to the foam.
